  1. Now that I'm back to building the music room (and finishing the walk out lower level) I have prewired the ceiling for 5.1.4 for one particular reason....Abbey Road Atmos mix. :) I am soo looking forward to setting up the system in a room designed for mch (i.e wider than Ohio room, so equidistant rears are comfortably at about 100 degrees). Great mch article Bluesman. We need all the mch support we can get. From Beck's Sea Change to Jared's great Budapest recordings. :0
  2. The is a nice series to show here on AS. Gets me thinking about volume controls and the plethora of places we can often find them in the computer audio signal path. Software players have them; dacs can have them; preamps, of course, are the classic place they exist...and even some power amplifiers have them (gain switches, etc). There are philosophies that each support a different place to do them correctly. For example, digital attenuation with upsampled material, throwing away "unnecessary bits" that do little or no harm! Bypass this or that volume control...are we really bypassing, or
  3. Chris, the discussion with Mytek's Michal was wonderful! I miss seeing him; during those early DSD years of 2010-2013 I was smitten with his early products and reviewed them ad nauseum (including running three stereo192DSD's in multichannel!!). If it wasn't for Michal's kind and generous nature, along with his special way of explaining technology I would likely never have gotten into DSD the way I did. Thanks for the interview; I need to look him up if we ever get to socialize in person again.

    HQ Player

    That dac is a sleeper. I heard it with mods that Dan Wright (modwright) did and it blew my mind. I should have grabbed it

    HQ Player

    In real-time. Offline with HQP Pro is the only solution currently.

    Could I implore you guys to please tell us the source file format when comparing upsampled PCM to remodulated DSD. It is much more a news item if DSD files have been down converted to Very high PCM and yet still have better timbre than when remodulated at, say, DSD256 In other words, I don’t find it unusual at all when R2R dacs present pcm files upsampled to very high PCM better than when PCM files are converted to anything DSD. My $.02
  7. ?? NativeDSD lowered the pricing for DSD64 almost a year ago (Nov 2019). Any "jacking" is due to exchange rates, not the site. As with any other music site, the higher rates cost more.
  8. Hols, thanks. I have always preferred PCM files staying PCM (and DSD staying DSD) with my Holo dac, for example. So your conclusion that even higher resolution 1411.2 sounds great with red book fits my expectations. I’d be very surprised, however, to hear that DSD to 1411.2 PCM ( an inherently lossy conversion) upsampling withstands and is superior to DSD remodulation. Looking forward to more experiments. 😀
  9. Hols, sorry to be so dense here, but are you saying that, with the endgame being PCM 1411.2k, any source files, even DSD files? IOW, you are saying DSD64 to PCM 1411.2k is better than DSD64 to DSD256 (using EC modulators), not to mention the cpu savings?
  10. NAA (Network audio adapter) is an HQPlayer audio daemon (application) that resides on a different box than the hard-working HQPlayer. Its intent is to isolate the dac interface from all that heavy lifting, and thereby reduce noise. All that runs on the NAA box is the DAC interface (driver). In the case of the Extreme, and the fact that, currently, HQPlayer V4 only occupies one of the Extreme cpus, the thinking is to install NAA on the OTHER cpu....thereby virtually creating a networked HQPlayer-to-NAA environment.
  11. Sorry I didn’t look up your previous posting experience. I will do a search to find out more about your NAA (OS, etc) edit: your build post doesn’t say whether your NAA is also Linux-based, like your non-Extreme server build
  12. Hols, what is your NAA computer? And will you report back when you do the NAA daemon on the other Extreme cpu instead? Also, does anyone have HQP V3 on an Extreme and can compare to a reinstall of V4 (being that V3 runs on both cpus and V4 runs, currently, on only one)? I realize auditory memory can be fleeting, especially after the time it takes to reinstall V4.
  13. Of course the final result (whether it be PCM to PCM, PCM to DSD, DSD to DSD or DSD to PCM) will be very dependent on the dac architecture. Over simplified, the Chord dacs will sound best converting everything to PCM, so even 384k or 768k will likely sound better than going to DSD256. My Holo dac is a dual architecture and when I had it set up optimally (prior to my cross country move 2 yrs ago) I commented that recordings sounded best when left in their format (DSD, PCM) and then upsampled/filtered within that limitation. YMMV
  14. I assume you meant “PCM 1536 with DSD256”. This idea that super high PCM might sound nearly as good and be more cpu-friendly is an interesting one. The real test is starting with DSD recordings cuz I think we mostly agree that PCM To PCM or DSD to DSD is normally ideal.
  15. +1 !! Every one of these albums are part of my life's soundtrack growing up, yet my interview with Ken would have lasted five minutes (think Paul being interviewed by Chris Farley ) not knowing the kinds of things you asked. Brilliant job.
