Once again, agree with @sander99. What I'm doing is an unconventional/alternate use of the Impulcifier capabilities to experiment with some different ideas. Read up on Ambiophonics and the discussion (perhaps 'cult' isn't too far from the truth) to better understand why I was interested in...

Yes, @sander99 is basically correct - just use Impulcifier to perform a normal binaural measurement of the FC channel. Then run the analysis as normal, and Impulcifier will generate a hrir.wav with only FC-left and FC-right elements being non-zero. Pull these 2 channels out into a normal stereo...

Yes, this is the debate that seems to rage any time ambiophonics gets discussed. It's tough to argue with - 'authorial intent' and all that. OTOH, on the right recordings ambiophonics can be absolutely mind-blowing - it was definitely the most jaw-dropping audio experience I've had since the...

Yeah, 20-degree is generally the recommendation. The math for XTC gets ill-conditioned at the separation gets smaller, and the wider you get the more the 'tonal inaccuracies' of 2-channel creep in. My inference is that the ideal is to be centered, but that doesn't work mathematically. I started...

Hi, New user coming up to speed. First, major props (and thanks) for implementing this. I've had this idea in my head ever since reading about the Realizer some years ago and have had my Sound Professionals mics stting around for a few years, but never got off my butt to do anything. This...

I have a couple questions on the mechanics of this unit that hopefully someone that has one can answer.   - when you apply power via the outlet, does it come up in standby or can it start playing directly? - if the answer to the above is that it comes up in standby,is there any remote support...

Somewhat OT, but for anyone that ordered this over the 'net rather than from a dealer, did it come double-boxed or was it just in the NAD box? I'm having to ship my unit, and while the standard packaging seems solid I'm wondering whether double-boxing would be worthwhile. The main problem being...

I haven't been paying attention to the portable scene at all for a while, so am looking for advice. I have a 30G Cowon X5L that has seen sporadic use over the last ~5 years and is still working ok, but I'm starting to notice decreased battery life and I'm getting a bit uneasy about the HD - I...

Quote:   I don't know for certain, but I'd assume that any volume setting above 0dB is going to apply digital gain to the incoming stream, and will result in clipping if the signal is maxed out. A way to test this theory would be to try apply volume control through your playback software...

Quote: The M51 apparently uses some form extended descriptor in the driver which isn't currently handled by ALSA. There isn't too much info, but you can dig through the thread on the slimdevices forum if you're interested in more info.  It's disappointing as running from the SBT via USB was...

I believe the HiFace2 is xmos based and supports linux.  IMHO I'd try the Touch /w EDO app native to see what you think before introducing an external usb->spdif link. Maybe I'm being cynical, or maybe I'm just not as thrilled by  'the chase of perfection' as I used to be, but I'm suspicious of...

Finally got a new source (new Aspire One netbook with a real-ish cpu rather than Atom which makes for a pretty nice poor-mans-ultrabook), and had a chance to try out the USB interface a bit. IMHO JRiver over USB even straight out of the box on an un-optimized PC seems to be an improvement over...

I got the O2/ODAC combo from JDS last week. I've only had a chance to do some brief sporadic listening over some HD280s, but my impression is that it is a substantially better combo than the Sparrow I used to have (Rev A I think - the upgraded version). I found the HD280s to be rather 'blah' on...

This was hotly debated in the speaker world when driver testing first rose to prominence. I sit a bit in the middle. Mathmatically, xnor is correct - that for any given impulse response measurement, it's possible to correct it to a near-ideal impulse.  However, I do think it's critical to...

Quote:   Very cool. Inspired by folks reporting that the Smyth Realizer actually really does work well, I picked up a set of in-ear binaural mics a while back with the intent of doing very much what you describe above. Additionally I wanted to experiment with HRTFs and...

Quote: I tried the 'audiophile desktop' style setup and didn't really like it. I found that with the computer there it was a constant distraction and I ended up dicking around on the computer rather than just listening.  I was hoping that the M51 would be supported by the SB Touch EDO mod...

Quote:   I'm still in the camp that is dubious that the M51 actually supports I2S-on-hdmi, but Channel Islands has an upcoming USB device that is multi-purpose. It has a built-in Wolfson DAC, spdif out, plus I2S out on either the HDMI connector or via the old Audio Alchemy mini-din. $695...

NAD M51 fits the criteria.

I'm using the M51 in our main TV system with an HDMI feed from our DirecTV box or from an Oppo dvd player. I haven't noticed any sync issues to this point.  I have had lockups and something in the chain - possibly the M51 - doesn't handle lo-def / standard-def resolutions, but at least it...

  Quote:   It's not reading the redbook layer - it's reading the DSD layer and doing an on-the-fly conversion to 88.2k PCM.  The redbook layer would in fact come through at 44.1.

  Quote:   This is how the Oppo players handle SACD as well - as 88k pcm. Assuming the Marantz is an SACD player, maybe this isn't all that surprising.  On the other hand, when I've had my HDMI lockups, I think the display has shown 88.2k despite the original source being 48k, so I...

  Quote: Interesting - missed this. I remain a bit skeptical due to the wording and the lack of specific compatibility info, but they are clearly using the term I2S though, so who knows.      

  Quote: I've had a few lockups with the M51 using HDMI as well. In my case my signal chain is  DirectTV hd box -> wireless HDMI sender -> M51 ->TV.  I believe that my lockups have been when I've power cycled the wireless HDMI sender while the M51 is on and set to the HDMI input. It seems...

I picked up an M51 a couple weeks ago, and unfortunately am struggling to find time to really listen due to ongoing reno work in the house.  I originally listened to it via a Stax 3050 set that I picked up, and was relatively impressed; not having heard the Stax with anything else though, it was...

I don't have a lot of content to contribute, but I just picked up a second hand SRS-3050 set (SR-303 and SRM-323II).  Not much seat time on them yet - hooked up directly to my new NAD M51 dac, and sounding pretty good. Maybe missing a bit of propulsive energy in percussion (e.g Rodrigo y...
