  1. View Classified Matrix Audio X-SPDIF 2 and Lifatec Silflex glass SPDIF cable For sale is a Matrix Audio X-SPDIF 2 digital to digital converter (supply your own power supply), with a Lifatec Silflex glass SPIDF cable. Outstanding SQ, esp. when powered well. Along with my NUC and tX-Ultra, this was part of my reference chain before I moved to the Taiko Audio SGM Extreme. $350, buyer pays shipping (CONUS please), I'll take care of PayPal fees. Please see photos and PM with questions (what is pictured is what is for sale)

  3. If helpful, if someone were willing to loan me an appropriate ADC, I'm happy to devote an afternoon to capturing files from these tests (both direct from laptop, and from an optimized source) I would then ask one of the civilians in the house to rename the files and load them for playback, and report whether I can hear differences between them. As a bonus, I'm doing a lot with upsampling for signal reconstruction. It would be interesting to have quality ADC captures of 1fs content vs 16fs content and see what the ADC shows us. (note: this is an OS X house, so I'd ap
  4. I would suggest that whomever does the digital capture compares the captured files to confirm that they are hearing a similar difference to what they hear in their system. If they do not, then that needs to be solved for before doing any blinded survey. I appreciate the spirit of this test and interested to see the outcome, but best to not have the interpretation devolve into a debate about whether the results apply to the capture methodology, vs whether the results apply to the cables under test. (bias disclosure: I've done tests with friends with Lush^2 cables in my living ro
  5. 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
  6. +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
  7. 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)
  8. 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
  9. 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.
  10. 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)
  11. 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)
  12. 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).
  13. @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'
  14. 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.
