    Odyssey Khartago and Stratos Stereo Amps

    A friend whose opinion I really respect pointed me towards these little jewels the other day. They seem to have to have garnered lots of good, albeit, informal reviews, and they are certainly priced right!

    Along with opinions for folks familiar with them, I was wondering what difference the "enhancements" might make. In particular, the main "enhancement" over the base models seems to have something to do with the power source.

    Specs are reproduced below - thanks for any comments.

    -Paul

    P.S. Is it just me or does the idle Power Consumption seem incredibly high for a solid state device?

    Are they Class A?

    That would account at least somewhat for the very high power consumption at idle.

    Hi Paul - These amps are a true "hidden" gem in hi end audio. They are respected by many in the industry. I'm not sure about the differences between the upgrades. I've been told to get them "with all the upgrades."

    I heard an integrated system with preamp, amp, and speakers

    The total was fantastic. A real quality system. Cost was very reasonable.

    Paul, I have had the base

    Paul, I have had the base model Stratos in my office system for several years. It is a very nice amp at any price as far as I am concerned. And, it is bullet-proof. One of my hobbies is designing and building loudspeakers and I can attest to it remaining stable into a 2ohm load. I do crazy things, sometimes.

    Hi Paul,

    The amps run in Class-A mode for the first 7-8 watts or so. Hence the idle power use. Unless you have low-efficiency loudspeakers and play very loud, you should normally not go outside Class A reach.

    The base model already has quite a large bank of capacitors in its power supply (at least double of what is recommended for 400VA).

    When in Class-A mode and not playing music, all the idle current gets dissipated into heat, but if you play music the dissipation gets less, and the energy is used to amplify. At that point, the capacitors in the power supply just deliver a static current, and as long as they have enough capacity to flatten the power-ripple after rectifying, all is OK. The base-model has quite enough capacity for that!

    The extra capacitor capacity (and VA's) start to make sense when playing demanding music; lots of changes or very extreme changes in dynamics, especially at higher volumes. Personally I would say that the base model should be more than adequate for that as well.

    As for the "better" components in the upgraded models... That is a tricky one. Some people believe those to provide better sound. I am not sure of that. But I am quite sure the "better" components (especially capacitors) just last longer.

    Hope this helps, and I apologize for stating the obvious (if I did).

    Peter

    Appreciate all the info!

    Thanks guys, it seems like the Khartago or Stratus might be a good fit here. I am thinking that the preamp they have might be a good fit too.

    Peter, I am driving a set of Maggies:

    Sensitivity: 86dB/500Hz /2.83v
    Impedance: 4 Ohm

    That would almost guarantee that they would not be in Class-A mode often, I think. Does it also mean that the extra microFarad's would be of great benefit?

    Also, with the NAD gear I virtually never turn anything off, though I do put them in standby. (Things break when you turn them off! - but with 30 watts of heat pumping out 24/7... in Texas... would turning them off be a big deal?

    Most of our electronics takes about a hour to warm up and stabilize from a complete power off cycle, so I am assuming this is also so with the Odyssey gear?

    It's like feeding the elephant, one question leads to another. I think I will also call these guys today. They didn't reply to e-mail in a couple days.

    Hey Paul,

    Even though the Maggies might not be the most efficient speakers around I believe they will be driven in Class-A mode longer than you think, unless you crank 'em up to party-levels on a regular basis :-)

    As for the extra Farads when going outside of Class-A... Like I said, the basic model already has more than is normally used (there are calculations for that). Honestly? I doubt you will be ever able to hear any difference. But I am sure others will disagree with me.

    I know I will probably get some feedback on this too, but I am not a believer in warm-up. Usually it takes just a few minutes for electrical stuff to reach their operating temperature. The properties of the electrical components do not change with temperature. Loudspeakers do, however. They move around :-)

    the only time I take caution about temperature is when I get really cold equipment into a warm room. Then I usually let it get to room temperature before turning it on.

    I get your point about stuff breaking when you turn them on and off on a regular basis. I have that experience too :-) But usually that is with stuff that has moving parts, at least for me. Luckily, amps do not move :-)

    Peter

    P.S. Seems this amp offers quite some bang for the buck... I am sure you will be very happy with whichever one you choose.

    On another note...

    Hi Paul,

    The primary function for capacitors in a power-supply is turn varying DC into steady DC (see the pictures here http://www.kpsec.freeuk.com/acdc.htm). They do that by storing "power".

    In order for that to function, they must store more than is asked. Basically this is a form of buffering. By increasing the "buffer" size you create a reserve.

    It is believed that if you add even more buffer-space than is needed for creating steady DC, you use that for extra current to be drawn by the amplifier itself, which is indeed the case. What makes the difference between audiophile capacitors and normal capacitors is the speed at which they release the stored energy.

    Again, I believe audiophile capacitors are usually of a better quality than the regular ones, and might be a good investment in the long run. But, do they truly offer a sonic improvement? Does a musical signal require faster release of the stored power to be amplified correctly?

    Peter

    Khartago with all the trimmings....

    Well, I ordered a stereo Khartago amp last December with "all the trimmings" and it arrived on our doorstep yesterday.

    The first impression was that it was packed really well - with some custom styrofoam inserts, and encased in one tough cardboard box. Instead of just tape across the top, the box is also stapled top and bottom for security.

    And once you pick up the box, you know why. That machine has got be heavier than 35 pounds! The aluminum faceplate is attractive and solid, with a very unassuming tiny LED set in the center to let you know it is on. Sitting on the bottom shelf of a Salamander 5 shelf rack, it is barely noticeable.

    The rear panel is clean and exceptionally well labeled. I was tickled to death that it also has my name engraved on a plate on the back. The speaker terminals are "WRT" terminals and very solid. The z-bannanas on my Nordost Flatline MK II cables fit in them snugly and make excellent contacts.

    The input plugs, for whatever reason, appear reversed. with the left input on the right and vice versa. They are color coded, so there is no problem plugging the interconnect cables in correctly, but you do have to look. It is of no consequence, but I bashfully admit I initially reversed the polarity.

    The top cover is very flexible, and well ventilated with largish holes. I assume there is some clever design behind that, but you don't want to put any weight on the top of this guy- he needs to stand alone. He has a shelf of his own here, and it is set too low for the cats to get on top of it.

    It's been running for a little over 24 hours now, and completely to my surprise, it doesn't put out nearly as much heat as I expected it to. Barely warm in fact.

    How does it sound? Well, that's the funny thing. Klaus warns that it needs to break in for up to six weeks, and until then it may have a bit of a "Jeckle and Hyde" nature. But I have been listening to it for the past couple hours, and well - I am more than impressed.

    It doesn't seem to add any coloration at all to the sound. I thought the T747 and the NAD BEE326 I was using were pretty neutral, and they are in absolute terms. But compared to this guy, they sound like they are muffled behind multiple layers of thick colored cotton. The music seems to hang invisible in space now, with a much wider and deeper soundstage. And absolute silence when nothing is playing.

    It grabs the Maggies with authority. It sounds like there is less bass, but there really isn't. It is just much better controlled, and that really gives me a thrill. The Maggies to seem to be playing easier - without a strain I didn't even know was there until it was missing. We had them playing far too loud for a little bit, without even realizing it.

    Obviously, this is a first impression, and I'll fill in more detail in a few weeks, after it has fully broken in. But initially at least, this is one fantastic amp.

    Photo of new simplified setup....

    This is the current main system setup. You can see the Khartago sitting there happily on the bottom shelf.


    The turntable is now upstairs, so the top shelf is empty and "cat territory."

    The Peachtree DAC*IT is hiding behind the little Touch on the second shelf from the top.

    The computer(s) and storage are upstairs in the office, where I can't hear them. There is a dedicated Apple network reaching this rack, delivered through an Apple Airport Express. A small 1000Base-T switch is hidden under the stand to provide the network distribution.

    On top of the NAD T557 BRP sits a WD HD Live Media Hub with a gig of storage and an AppleTV. The WD Live is storing the most watched movies and programs locally, but also accesses Vortexbox storage upstairs to be able to play the entire library.

    The AppleTV is "jailbroken" and also accesses the same Vortexbox Storage upstairs and can play the same content. However, in the current version, MKV video files do not play acceptably well, and even some VOB files play poorly. iTunes videos and Netflix play exceptionally well from the AppleTV, and tellingly enough, they do not use any of the "jailbroken" functionality. The intention was to use just the AppleTV device, but that isn't possible yet.

    The NAD T557 plays Bluray and DVD disks exceeding well, and sounds very good as a CD player. The Touch and Peachtree DAC*IT easily sound better than CDs, but Bluray disks, most opera's in particular, sound very good on the T557 indeed.

    The T747 is now regulated only to "preamp" duties, because there are three HDMI sources feeding into it. (The T557, the Western Digital HD LIve Media Hub, and the Apple TV.) I am currently on the hunt for a Dac/Preamp with HDMI passthrough to replace the T747, but it's not as easy a task as it sounds. The Linn DS and NAD M51 series seem to be real possibilities though.

    Attempts to replace the NAD T557, the Apple TV, and the WD Live with a quiet PC running JRiver Media Center have so far met with only limited success. A PC quiet enough to exist out here in the living room does not seem to have enough processing power to run JRMC well. That's especially true when you ask it to do any video tasks.

    A unit that is utterly quiet, and can handle the music and video duties would be ideal, but so far remains out of reach.

    Dressing cables with this shelf is - ah - a challenge. All the power cables are routed separately from the audio/data cables, which are currently not really dressed at all, just hanging free behind the stand. The network switch is hidden underneath the stand with the power cables.

    The next step is to get the gear "floating" on the shelves.

    Stratos/Khartago

    Well, I think you will be pleased. Only a couple days of listening, but it seems to be a vast improvement with the 1.7s.

    I can only suggest the Strato's will be as good or better.

    Odyssey highly recommended ...

    I have a pair of Stratos Monos and I love them. They are the one thing in my system that I have absolutely no qualms that they are as good as I will ever need. I think odyssey gear is perhaps the best deal in audio right now (perhaps along with Magnepan 1.7s What I cannot emphasize enough is how great Klaus is to work with. He builds each piece to order and tries to customize it for you. (My Stratos amps, for example, are in smaller Khartago cases with the internal heat sinks.) Odyssey power amps are truely remarkable. Put them beside the big names that cost 5x more and they will not be outclassed. In my opinion you have to get into true exotica before you will find something that really outclasses Odyssey.

    I can vouch for the previous comments about their amps being very, very quiet. When the front end is turned off and the power amps are on (which is all the time, Klaus recommends they stay on continuously) there is practically no perceptible noise from my speakers, dead silence. For the price Odyssey cannot be touched by anything I have used. Anyone considering Odyssey but hesitating because they are relatively unknown should just take the plunge. You will be rewarded with a piece of gear that will be satisfying for a long, long time.

    Odyssey vs. W4S vs. Bryston

    I'm setting up my own amp shootout soon. I have the W4S SX-1000 monos. I ordered the Odyssey Stratos monos and a Bryston 4B SST2. I was going to use the Parasound A21 instead of the Bryston to keep all of the amps around $2500 but everyone I talked to and everything I read said "Try the Bryston, try the Bryston...". The winner stays and the loosers go back or sold on AudiogoN.

    Update...

    Wowzers....

    With a little over 150 hours of power on and playing time, the Odyssey impossibly keeps getting better and better. I just listened to Jeff Wayne's War of the Worlds tonight, and it was so much better than I had ever heard it, I had to listen to parts of it twice.

    This is an album I know very well indeed, and it has never sounded like this before. Even on "high end" equipment and systems well beyond my means. The only thing that changed here since the last listen was the amp

    I have put some borrowed rather high end gear into this system before, and it has never ever sounded as good as this Odyssey amp does.

    The sound can only be accurately described in negatives, if that makes any sense. What isn't there is any noise, grain, flatness, distortion, coloration, and the like. You do have that automatic feeling that you are listening to an amplifier.

    How it gets better than this in terms of amps, I can not even imagine. I am supremely happy with this guy. Now to get a preamp to match.

    If you are looking for a new amp, do yourself a big favor - call Klaus and have a chat. You ears and your wallet will thank you.

    Stratos monos

    Paul,
    I'm a little behind you in the process. I received my Stratos Monos on Wednesday and after a few QC issues I have them up and running. I will take a listen and post some initial impressions over the weekend.
    Warm regards,

    Cyclops

    Hey guys .. got off the phone with Klaus just a short while ago and I ordered a Cyclops Extreme/SE. I'm sure you know it's an integrated (Khartago amp with a volume control and just 1 input). I have to wait about 3 weeks or so. Looking forward to hearing more of your experience with break-in while I wait. Paul, from your posts it sounds like the amp is a good match with your Maggies. Frank, I hope you feel the same. Needless to say I'm encouraged.

    After about 100 hours and

    After about 100 hours and from memory, the Stratos sounds smoother and less edgy than the W4S. The W4S bass has more wallop but may not be as deep. Soundstage seems about the same, the Stratos may be a touch more three dimensional. The Bryston will be here tomorrow.

    The Odysseys will continue to change...

    From what I remember (I have a set of stratos monos and my dad has a stratos stereo extreme) the Odysseys took months to really come into their own. As good as they are now, I'd bet yours will continue to get better.

    300 Hours of Power On Time / 200 play hours

    Listening to Tracy Chapman's eponymous first album from 1982. This Odyssey amp use continues to get better and better.

    At about 200 hours we noticed the bass dropped out, but was back the very next day clearer and more detailed than every. Just as Klaus predicted it would do. Still, the level of sound from it just gets better and better and better.

    What I am noticing today is that while the amp sounds more powerful, I think that is because the mid bass is presenting with more control. Soundstage is still the same, but imaging is more forward today. Flutes especially are coming through with the breathy percussive impact that a very good flautist can achieve.

    On the standard tracks I am using to measure the amp, things are sounding better, and in accordance with what I a described hearing above.

    Klaus and crew are quite simply miracle workers. Every day I wonder how it is possible this keeps getting better. This amp has to be one of the great audiophile bargains of all time - right up there with the Maggie 1.7s.

    700 Hours of Power On / ~600 hours of playing time

    Was listening to a television program from Netflix on Friday evening, and Karen and I both noticed how really good the theme music sounded. Finally realized that it wasn't the themes sound, but that something had snapped into a laser like focus with the Amp.

    Just spent the last few hours listening, and wow....

    Eveything just sounds right with the amp now. The bass is there, with an authority I have never heard before. Just balanced perfectly, not even a hint of grain a wide and deep soundstage. We realized we were playing it louder than we usually do with no distress. It is shocking how well this amp just snapped into focus.

    It has always sounded right, but now - well - it simply sounds like it isn't there at all. There is no sense of strain, no sense of anything being missed, and apparently, not enough distortion to distress us, even when we are listening to things too loudly.

    Pink Floyd's Atom Heart Mother sounded flat out spooky. The Breakfast track - well - you would have sworn you were in the kitchen.

    The OST from The Chronicals of Narnia: The Lion, The Witch, and The Wardrobe sends chills down my back. Wunderkind by Alanis Morriset is reproducing the grittiness and fullness of her voice, without it sounding annoying. That takes doing...

    The song is quite appropriate for this amp tonight - Wunderkind indeed.

    Now I can hardly wait for the matching Cadela pre-amp to get here. I have no idea how it can possibly improve on what I am hearing. I think I could happily listen to this forever. Or at least, a very long time.

    Really good stuff.

    I've been researching this amp and just decided to check here for anything and found this thread and your excellent time-based review.

    Thanks!

    Looks like a keeper.

    I'm looking at the Cyclops - thoughts on that?

    Track 2 on Atom Heart is awesome isn't it?
