  1. Just received my 2nd Sablon Audio King power cord and updated review with the following: UPDATE (2/26/21): I have received my second Sablon Audio King power cord (20A IEC, from the wall to my TT-7). (Un)Surprisingly, adding the Sablon 20A King on TT7 PGI 240V is another first 3 seconds “I'm done here, no more listening tests needed” experience, even before burn in. There is a magic synergy going the wall to Sablon King to TT7 to Sablon King to Taiko Audio SGM Extreme. If you're investing in a Sound Application TT7, do yourself a favor and track down a Sablon King power cord to audition wi
  2. +1000 this. The amount of hard core engineering that goes into these factors is off the charts. I too find it amazing that folks extrapolate idealized abstractions to how things actually work at the physical layer. Abstractions are critical for operating at a higher level (network stacks, switches, kernels, etc), but we have to focus on the reality at the level of reality we're trying to manage/optimize. If you care about the ground and reference voltage plane and how noise (and self induced noise) on these planes impacts a D to A circuit, you have to operate at that level, no
  3. These days, I'm listening to a lot of 16fs 32 bit content (705/768kHz) as wav files. When files get bigger than 4GB, I'm splitting them into multiple parts. With players that support gapless playback (HQP, Roon, etc), this is no issue at all. The parts play as intended, even with the 4GB limitation With all this preprocessing, I appreciate being able to get content in as close to the mastering format as possible (less about information content, more about information quality after digital processing....basically the same reason the mastering system does processing in 32 bits)
  4. This is true. DAVE 5V draws 0.7-1A (or so). LPS 1.2 really shines at lower current draw. That being said, LPS 1.2 5V >> DAVE SMPS 5V (at least in my living room). A higher current capable device (ldovr, JS2, etc) could be higher performing still. For example, I thought the ldovr 3A 5V supply to perform better than the LPS 1.2
  5. Tom, this is awesome! Getting access to the 32 bit masters is a huge value add. Appreciate all the extra work to put an extra version out there for us.
  6. Remember that you have -15V as well, so you would need three supplies. These supplies have enough current for the job so they would work. How they would compare to other options is TBD (I've tied multiple supplies on the 5V rail, but I did not have a Farad to test...they all have a different characteristic sound)
  7. It is certainly worth trying (and shouldn't cause any issues). The IT does a great job of filtering noise, but it stunts current dynamics. With your modem, not really an issue, and it isn't impacting the Extreme (where it is an issue)
  8. Ultracap is awesome for being mains isolated. There is a huge win there. I have not tried it with DAVE, but I am tempted based on your report (thank you!) The 3A ldovr supply gave me an intriguing result when I tried it to power the 5V line on my DAVE (can't/won't say better or worse, but definitely had its own character). It would It does give you access to higher voltages as well (although I suspect the characteristics of what makes an optimal supply for 5V will be different that ±15V...the jury is still out for me on that one).
  9. @barrows is spot on. It is all about balancing tradeoffs, since there isn't an ideal (yet). The insidious thing is that a recipe/scheme that works astonishingly well for one person, may have marginal impact for another person. The trends and tendencies and levers are pretty clear, but getting to the right balance is very much dependent on your system, your home, your environment, and your ear/brain. For example, Rob has shared that when he got a new laptop, the balance and impact of toslink and USB changed for him. Not a surprise, but very easy to forget when we'
  10. All that depends on when Emile can get his USB card out for eval! With Taiko Audio Server, the Taiko network switch isn't going to matter very much any more.
  11. From my experience using the alpha release of TAS, above is spot on. Very clever and very thoughtful implementation, with meticulous and systematic attention to every detail. Emile and team are bringing the same focus to software as they do to hardware and system configuration.
  12. I had a nice lift powering my Matrix Audio XSPDIF 2 with a LPS 1.2. I miss that relaxed presentation, but I'm a sucker for transient timing (aka, more taps!). Slowly getting back to that place, but it is taking a lot of effort. Everyone should at least try the optical in on a Chord DAC, just to hear that baseline.

    When not crashing NAA or glitching during playback, @Nenon's experience is the same as mine. 4.9.0 was a significant step up in SQ with a dual CPU system, HQPD running on one CPU, NAA running on the other (I believe @Nenon is running a similar config) 4.9.2 (with the fix) gave up some of that, but not all of it I suspect it is not the bug but how data is being passed between processes? If there is a way to understand that and optimize it, that would be a huge step forward (the improvement with 4.9.0 was decidedly non trivial) If you're not hearing it in your test setu

    Great recipe! To pile on here, if you are able to try this (2 computers etc), you most definitely should. Booting off a USB stick makes it a very experiment to do (then undo). Delightful how many problems and annoyances simply go away when you have a stripped down end point that is optimized for one thing and one thing only.
  15. I have two ERX’s. I go ISP to fiber to “modem” (ONT) to Ethernet ERX1 to SFP fiber to ERX2 My home network and wifi is all in ERX2. My audio network is isolated on ERX1 (it’s own subnet) and I use a Sonore optivalModule to connect ERX1 to my server via fiber. Getting my audio network on its own subnet was a big deal. So was optically isolating wifi on a different ERX

    Well the magic is awesome! If helpful, happy to help figure out what is happening on my system so we can take advantage of this very welcome coincidence (I've heard similar reactions from several other people, but it may be very system dependent)

    Looking forward to listening to this later today! Most of the NAA magic of 4.9.0 was lost with 4.9.1, so very hopeful to hear it again!
  18. To add to that Ted, TAS allows you to choose your playback engine: the proprietary Taiko one or HQP (in case you want upsampling), similar to what you have with Roon. TAS is tuned and optimized to how Taiko has provisioned and configured the Extreme (and soon, their Evo server). I'm running the TAS alpha, and using HQP+NAA for the playback engine, so I can take advantage of upsampling for streaming content.
  19. One of the best values in audio is the (now discontinued) Chromecast Audio end point, with toslink to DAVE/Hugo2/etc. $50 to test the optical interface, and for most folks, as far as they will want to go (search for "Chromecast" here for details https://www.head-fi.org/showcase/audiowise-opto•dx-optical-isolation-bridge-for-dual-spdif.23757/reviews#item-review-22155 ) When I was still using mScaler, my preferred interface was Matrix Audio XSPDIF 2 (USB in, TOSLINK out) to mScaler. It was only when I started doing software upsampling that I went back to USB (alas, TOSLINK is limit

    This is fantastic! Any way to tweak buffer size to see where an optimum point might be? This is definitely a needle mover, and most appreciated!

    A very material upgrade for NAA users! (PCM guy as well, in case that makes a difference) @Miska any hints on what types of NAA optimizations could have this kind of impact? If there is any more that can be done in this same direction, yes please!
  23. Very much looking forward to hearing what you hear!
