  1. MQA is Vaporware

    I think what actually happens is that most music is recorded at 24/44.1 or 24/48 and possibly Mastered in 88 or 96. Not the same as being recorded in those high resolutions.
  2. Professional reviews and my personal review. FYI, the Kiis are an active stand mount speaker employing DSP, and 6 drivers each (tweeter, mid, 2 rear, and 2 side firing woofers), and each driver has its own amp, D/A and A/D converter. The side and rear woofers employ DSP controlled timing so that there is virtually no side and rear firing behind the speaker. The rear and side reflections are almost all cancelled out. Everything left is fired forward in a "cardoid" pattern, so room interaction is much reduced. The whole setup is also time aligned, so sound from each driver arrives at the same time to your ears. And because of DSP control of the woofers to prevent over firing and distortion, the system can play full range from 20- 25kh, with an extremely small rolloff at the bottom. The system can also be adjusted for non symmetric or close to the wall and corner placement. More info and measurements in some of these published reviews: https://www.stereophile.com/content/kii-audio-three-loudspeaker http://www.audioxpress.com/files/attachment/2609 https://medium.com/@conscienta/kii-three-review-a-revolutionary-speaker-759c15b014cf https://www.soundonsound.com/reviews/kii-audio-three http://kiiaudio.com/en/component/phocadownload/category/1-revies.html?download=7:studiomagazin-kii-three-review-english http://tapeop.com/reviews/gear/120/kii-three-active-monitors/ https://bobmaccsblog.wordpress.com/2016/10/10/kii-three-speaker-review/ I've had the Kiis in my small listening room for about 2 months now. Am very pleased and don't miss the Devore Nines, as good as they were. I listen in a small room. I started looking for something different b/c I wanted a system with actual low bass output (without a big rolloff below 30hz), and something with more realistic dynamics than what I had (read, "will play back orchestral music, with it's big dynamics, more like the real thing"). And something that with those attributes, that could still sound good in my small room. I was also looking to integrate and simplify - reduce the number of boxes and cables. Obviously, I also had to think the setup sounded good in general, and didn't just tick off those attributes on paper. Larger conventional speakers and subs weren't the solution - too big and overload my room, even with full room treatments. I've used solutions like TACT and Lyngdorf in the past - they pretty much worked, but I didn't want to go in that direction. Plus, it wouldn't really get me the dynamics I was after. That led me to audition the Kiis. I did a pretty extensive audition at a dealer (no dealer where I live and no possibility of home audition, unlike in other places), listening to all types of music, including tracks I think are hard to reproduce well. I ordered them on the spot. So how do the Kiis sound? The basic words to describe them are "clarity, coherence, and balance ". The sound is very clear and detailed without sounding forced. Lows, mids and highs sound balanced, without special emphasis, and are well blended and coherent. You really can hear every detail: Every nuance of what your favorite bass player is playing. Every little tap on the cymbals and tone change of your favorite jazz drummer. Those lyrics you never could make out because the singer mumbled? Turns out with the Kii you understand them - the singer wasn't mumbling. Quiet sounds amidst louder ones all around in the mix? Yep, those details you never heard before are audible. There's also very good soundstage/depth, and placement of instruments in space is clear and rock solid. I listen to a fair amount of orchestral music. One of the pieces I used to audition the Kii's was Mahler's 6th symphony - which I'd heard performed live just a few hours before. The Kiis can produce a very loud, clean, full frequency playback of this piece, with startingly real dynamics and a decent soundstage/depth - even in my small space. I don't think there are many (any) other systems that could. The clarity of the Kii's is very different from pretty much any conventional setup. The cardoid bass and precise timing control lessen unwanted reflections and improve the timing of what reaches your ears so that at first it seems something is missing. But then you realize that's what's missing is a kind of distortion/fuzz caused by room reflections and a lack of precise timing between the drivers in conventional setups. It's a kind of fake upper-bass/midrange "warmth" that shouldn't be there. I'd guess there's a fair number of listeners who are used to that kind of fuzz and think it is part of a "natural sounding" sound. I respectfully disagree. You've just trained yourself to think that's how playback is "supposed" to sound. The Kiis will tell you when you are listening to a substandard recording. They sound like the real thing, but they won't make your music sound nice if the recording doesn't on it's own. And yes, due to their DSP controls, they sound the same placed in the corner as they do more out in the room. Okay, lots of praise, but how good are they, really? I'd say this system, for a similar cost, is about two orders of magnitude better than my previous conventional one. Could it be beat? Well of course, it isn't perfect. You could spend 15-20k or more and get speakers with 3K custom made tweeters that would give you a little more high frequency extension and a little more decay. The Kii's are good at that, but I won't say they can't be improved on. The bass from the Kiis goes very low, as low as most subs, and is done well. They successfully playback low organ notes or low bass produced electronically in modern recordings. More than enough bass for almost anyone. But, in the end they are small speakers and won't give you the same physical impact as a 15-18 inch woofer powered by hundreds of watts. If that's a must for you, look elsewhere. And no, they probably don't have enough output to play loudly at full response in a large room or in one with double height ceilings. They will play plenty loud in most rooms, but not in all. So yeah, you could spend three times the cost on speakers, a DAC, subs, amplification, and cables and get something that would be as good or better than the Kiis in some areas. But you wouldn't get that amazing clarity....Oh, wait, you could add a box like a DEQX and approach it. But you get the point. I think for the money they are an amazing value. In a small to medium size room, or in an otherwise challenging listening space - you can't come close to beating them for the money. Every system has its tradeoffs. Decide if the ones made by Kii make sense for you.
  3. You are aware that the mR has USB cleanup circuitry similar to the Regen built into it?
  4. One problem I see at ASR is that they confuse "taking a measurement" with arriving at a scientifically proven conclusion. They don't seem to understand the difference. Another is that many posters there seem to revel in being nasty jerks. I tried to point out that there is a difference between measuring something - what the posters there insist, for some reason, is the same as a scientific proof - and coming to a scientifically valid conclusion. For that effort I was repeatedly insulted there, and won't go back. I won't be surprised if this post also gets me some defensive and nasty replies from some of the people that post there....
  5. MQA is Vaporware

    I think if you check you will find most albums are made in 24.44.1 or 48 and not higher resolutions.
  6. MQA is Vaporware

    I and some others actually did get free upgrades to higher resolution versions of some albums when they became available.
  7. Don't have the time to look now. I'm going on vacation and am running out of time to do everything I need to before I leave. AFAIR, Harman did some tests showing that trained listeners could detect such things. I might have it confused with something else. But as noted as ASR, Amir himself says he passed such a test with hi-res. Years ago there was a "jitter test" published online with a file given various levels and also no added jitter. There were people who did testing with these files and succeeded in identifying quite low levels of jitter. As I recall, I could fairly reliably differentiate the file with 30 ns of added jitter, from the file with 100. The file with 100 wasn't hard to pick out. Below that it got difficult to hear for me. Oft quoted by people claiming to represent "science" is a figure that jitter below 50ns or 250ns is inaudible.
  8. Wow, Sal, have you lost your reading glasses? I've said nothing of the sort. You keep projecting onto my posts things I haven't written. Even when I agree with you and Amir you somehow find it objectionable. Please find one post of mine among the thousands here where I claim that one should only "trust their ears", and ignore everything else. If you want to debate me, please debate what I post, not some imagined version that exists only in your head.
  9. Sal, can you please stop just trying to score points? You are arguing and being insulting about claims I didn't make. You made a broad generalization about "subjectivists" being in denial. My response was that "objectivists" also exhibit this trait, and I gave a few examples: Look around the net where it is constantly claimed that "science proves" that listeners can't differentiate between hi-res and redbook, or between moderate and low levels of jitter. Yet, it has been shown that trained listeners can do both in properly conducted tests. So you and Amir are only confirming what I said, not the opposite. I'm not sure how we disagree here. In spite of this, when tests like this come up, many "objectivists" will repeatedly claim that "the test was flawed", because the results go against what they "know" must be true. So in that they are no different than the people you claim are in denial. Just surf a bit and you will find examples. Beyond that, I posted at ASR a request to Amir that he stop cherry picking my posts here, distorting what I said, and then using them to score debate points. Quite disrespectful, and even obnoxious behavior, IMO.
  10. Another major look at MQA by another pro.

    Yes, originally they talked of having an individual deblurring filter for each DAC. Apparently that isn't true anymore.
  11. Roon Vs jriver

    It all depends on how you interface with your collection and what you are looking for. JRiver is great with its UI built for a large screen. It's great if you conceive of your collection in folders and want to navigate it that way. It also does things like video, that Roon doesn't. If you know exactly what you want to listen to, use JRiver. Roon is a different user experience. It's for people who like to see relationships between different albums and artists. For people who like to recreate, in a sense, the experience of the LP cover and it's information. For people who like to have instant access to Internet info related to their music. And for people who like to do a bit more wandering in their collection, or have their playback UI "surprise" them by reminding them of something in the collection they haven't listened to in a while. And of course, it gives you full integration of Tidal into your library.
  12. Another major look at MQA by another pro.

    Sometimes the answer is obvious, no? Why keep asking. Use your brain.
  13. Another major look at MQA by another pro.

    Good way to put it. The anecdotal evidence by users who find upsampling MQA files to DXD rates -without the MQA processing - gives a sonic result indistinguishable from MQA unfolding and filtering is also an indication you are correct.
  14. Another major look at MQA by another pro.

    Not quite sure I understood you. Are you saying that in every instance you've measured the MQA version of an album has a different and higher DR measurement than the non MQA version? And meaning the MQA version is always a different master? What happens with the 2L files that are supposed to be files with MQA from the same master?
