  1. The speaker spec that determines the power requirement of the amplifier, is the sensitivity of the speaker. That is to say, how much sound a given speaker will produce when fed ONE Watt measured from 1 meter away directly in front of the speaker. For instance, a speaker rated at 85dB is considered a low efficiency speaker and needs a larger amp than one rated at 95dB which is considered a medium efficiency speaker and requires fewer Watts to achieve the same volume level as the one rated at 85dB. A 105dB or greater speaker is a high efficiency speaker and an amp of 10 Watts can run you out of an average sized room, it's so loud. When I was a teen, a buddy of mine's dad had a pair of Klipshorns. We hooked a 6 transistor radio to the thing one day and it played so loud we had to turn it down! The radio put out about 100 milliWatts (1/10th of a Watt)! Another consideration is room size. If you have an average size modern living room of approximately 10 ft X 12 ft (3 meters X 3.66 meters) then even a very inefficient speaker of 85dB@1Watt/1 meter should not need more than 100 Watts/channel to literally raise the roof! Of course, bigger rooms require more power to get the same volume levels (or trade-in your speakers for a more efficient pair and keep your 100 Watt/channel amp. (see the relationship?) The speaker's watt rating is the maximum power that the speaker's voice coils can handle before they get too hot and damage the speaker. That does not mean that you couldn't use a speaker rated at 250 Watts max with an 500 Watt amplifier. It is unlikely that you would ever use anywhere near the 250 Watt rating of your speaker, much less the 500 Watts of your amp! Most people never use more than a few watts of whatever sized amplifier, anyway, except on loud crescendos and very deep bass like a large pipe organ. That's where the power is needed. On power Vs volume: In order to double the volume of a 50 Watt amplifier, you'd need to increase the power to a 500 Watt amplifier! That's the relationship.
  2. Integrated Amp / Stereo Receiver

    Like I said, I'm going by a glowing review for both the pre-amp and the amp in a British Hi-Fi publication known for their honesty and good advice and by the fact that I reviewed an Emotiva preamp (not this one) a number of years ago and found it excellent in every way. I have no experience with either component I wrote about, above. What did you find wrong with the sound of the A-300?
  3. Integrated Amp / Stereo Receiver

    This would have to be used because H-K doesn't make this any more, but the Harman-Kardon HK-900 is a magnificent integrated amp. It has both MC and MM phono stages, a built-in 24/192 DAC, and DSP equalization for matching main speakers with sub-woofers and dialing the system in for the room. It is true dual mono with separate toroidal transformers for each channel and puts out 150 Watts/channel into 8Ω and 300W/c into 4Ω. But, I just read a review in the British Mag Hi-Fi Choice for two pieces of equipment from Emotiva and they rave about the performance/sound quality of these really inexpensive pieces. They are the BasX PT-100 which is a full pre-amp with a built-in 24/192 DAC, MC and MM phono inputs and a very good FM tuner. It's $300* and it looks well made with a CNC front panel, vacuum fluorescent display and a remote. Next is the BasX A-300 power amp. 150 WPC @8Ω and 300 WPC @4Ω! Again the cost is just $300* HiFi Choice gave both units their highest accolades while puzzling why other comparable performing components cost so much more! I reviewed an early Emotiva Preamp several years ago and found it to be beautifully made, with the highest quality components, and magnificent sound. If I hadn't already sprung for an HK-900, I would have bought the review unit! * Yes, those prices are correct. Go to Emotiva,com and check them out for yourself. Look under the BasX components for the full dope on these bargain pieces and a look at the entire line. the price/performance ratio is simply amazing for this US based company.
  4. I don't know what Ontario Law is, but this doesn't just smell fishy, it IS fishy. First thing to do is look through all the paperwork that came with this amp when you got it (you did keep it all, did you not?). Look for the warranty info. Read the warranty thoroughly. It should say that the amp is guaranteed to be free of defects in both parts and workmanship for some period of time (you say it's 2 years). If the warranty is for 2 years, and you bought the amp in 2017, then it's still in warranty, and the manufacturer is obligated to repair or replace the unit at no cost to you as long as that course of action is clearly stipulated in the warranty paperwork that came with the unit. If you find that have fulfilled all of your warranty responsibilities (such as filling-out and mailing the enclosed warranty card [if any]). Then call the manufacturer and threaten him with going to the Better Business Bureau and complaining (I believe that Canada has those). If your local newspaper or broadcast media has a consumer help line or column, threaten the manufacturer with that as well. In my experience, most high-end equipment makers are quite small and can't afford any negative publicity. Most honest companies will bend-over backwards to correct a problem when threatened that way. If that doesn't work, and you are sure that you are legally in the clear with your warranty demands, then threaten a lawsuit. But if you are wrong about what your rights are in this case, and don't really know where you stand, legally (believe me, the manufacturer knows his!) don't play this last card, as it could backfire. KNOW YOUR RIGHTS THOROUGHLY before threatening any legal action!

    I wouldn't worry too much about THAT! 2020 will be here soon enough and I'll bet he doesn't even run again (and if he does, he will lose big time). The Dems will sweep both houses in 2018 and that'll put a further hitch in Donny's get-along! Hell Even the republicans don't like him or support him all that much. We need to drop this line of discussion before Chris puts the ky-bosh on us!

    It's not the amount of tax US citizens pay that bothers me so much, but it's rather that we don't get anything back from our taxes. Niggardly SSI, no paid health care, no paid maternity leave, no livable unemployment insurance; hell, we can't even afford to keep our own infrastructure properly maintained. All we get for our taxes are endless military misadventures, paying corrupt and otherwise useless politicians, and servicing the largest national debt in the history of the world.

    Like I said, many European countries actually GET something in return for their tax dollars, we Americans do not! We can't even get decent single-payer health care for our tax dollars. Everything that either party proposes has the insurance companies involved, and believe me, as long as that's the case, health insurance will remain inadequate in this country.
  8. Schiit Saga vs Freya

    Here's the important question: you say that you hear it when the volume is advanced to maximum and you put your ear close to the speaker. Do you hear the hum (at all!) when playing music at your normal listening level, and from your normal listening position. If the answer to that Q is yes, then it warrants further investigation. If, on the other hand, you don't hear it at normal listening levels from your normal listening position, then it is purely academic and I say, forget it and go back to listening to music.
  9. Next upgrade...Eames style lounge chair?

    For optimum listening, you don't want a headrest! Maybe a neck rest , but you want your ears clear of any encumbrance
  10. Next upgrade...Eames style lounge chair?

    My experience with an Eames chair exactly!
  11. Next upgrade...Eames style lounge chair?

    I've got an Eames-style chair, but I don't find it very comfortable. The arm rests are too low and one tends to slip down and out of it because when one sits in it, the chair rocks forward on its pedestal. I keep it for guests and never use it myself. Oh, it's beautiful, no doubt about that and in a photograph from Architectural Digest, in a setting of a modern glass-walled house with other modern furniture (like Maies Van der Rhoe's "Barcelona Chair") it looks great. If you want a listening chair, buy a listening chair. You want something without a full-width headrest and without wings. If you think about it in terms of your ears, I think you'll see why I say that. Ideally, I'd like to have one of those "home theater" chairs, but the ones I've seen are only available in pairs and I want a single because I live alone.

    This is way off topic, but I was answering a another posters Q about why prices for audio gear are so different between the US and GB. If you look further, you will find that while our Federal income tax may be fairly low among the nations of the world (I know that some countries have taxes that are much higher than the U.S.). But, as I said, when one adds-in all the other taxes that we Americans are privileged to pay, the picture becomes somewhat different. The great American Supreme Court Chief Justice Oliver Wendell Holmes once said "I don't mind paying taxes, It's how I help buy civilization." Well, maybe in his day that was true, but in this day and time, all it buys is more government waste, mismanagement, continuous warfare (the US has had troops deployed CONTINUOUSLY for more than 30 years) and misguided entitlements. I say, if we're going to be the world's police then let the rest of the world help pay for it! Then, perhaps, we can get "all those things ( I ) claim that we don't have the money for"! Now, Let's get back to the RMAF Reader Reports.
  13. Does Gungnir have same glitch that Yggi has?

    The biggest measured difference between the Yggy and the Gumbi is, AFAICS, is the ultimate signal to noise ratio. the Yggy is -121 dB and the Gumbi is around -117 dB. I too believe that I would have been just as happy with a Gumbi as I am with the Yggy.

    We don't have a VAT in this country (but it gets discussed in Congress every now and again). Individual states can have a sales tax, and it varies from state to state with some having no sales tax and others having a considerable one. The highest sales tax in the country is in Illinois with 10.25% (Chicago) and States like Delaware, New Hampshire Montana and Oregon have no sales tax. But the tax is never folded-in to the advertised price of goods, because the tax is regional and not fixed. People who live in states bordering those states with no tax, often will travel to the adjacent state to save money on big purchases. I live in Northern Nevada. Our sales tax is around 7.6%. If I went to Oregon to purchase my new $30,000 car, I would save almost $4000 in sales tax alone. Not an inconsiderable amount! One could buy a nice pair of speakers or perhaps a new amplifier with the money saved! We also have, on top of state sales tax, a state income tax which also varies from state to state. Here in Nevada, for instance, we have no state income tax, but in adjacent California it's about 12% of one's total yearly income. Then of course there's the federal income tax which is on a sliding scale and dependent on ones income group or "bracket". The highest tax bracket is, I believe, about 39%, but most Americans pay far less than that. A lot of Europeans think that we Americans are under-taxed compared to many European nations. This is a gross misconception. We Americans with sales tax, state and federal income taxes, excise taxes on luxury goods, property taxes, yearly vehicle registration taxes, etc, run easily to well over 50% of our income. The main difference between many European countries and the U.S.A. is that most Europeans actually get something back for the money they pay in taxes, such as decent medical insurance, state paid maternity leave, decent pensions and unemployment payments that are a large percentage of their working wages. We do not. We have an infrastructure that's falling apart because there's no money to fix it, underfunded national pensions (called Social Security) which is a joke, inadequate public schools (we once had the world's best public education system) and on and on. Why, with such high taxes, are we so far behind the rest of first world? Because we have to pay for being the world's police. Our defense budget and our entitlements takes up so much of our money, that there is little left for anything else, and so we have to borrow money from other nations just to make ends meet. The result is that the United States is the largest debtor nation in the history of the world! End of soap-box rant.

    Don't British prices often include VAT? Isn't that around 20%? Just asking, but if that is the case, then that would explain the delta between the US and British prices in dollars. For years, it was SOP for audio goods to cost in pounds sterling what they cost in dollars in the USA, and this was when a pound was as much as $2.00 meaning the stuff costed you Brits twice what it costed we Yanks. Luckily, I don't see that kind of delta any more as the pound sterling and the dollar have moved closer together.
