My RME ADi-2 fs (AKM4493) responded very favorably to an iFi iPower Elite. No doubt this is better still. RME DPS-2 Manual: https://rme-audio.de/downloads/dps2_e.pdf

Agreed. The 6DJ8 is the original noval tube type here, with the 6922 being a much improved (and longer life) version of it that was developed later. IIRC, a true 6922 should have a 10k hour heater life (the limiting factor for tube life). Other 6DJ8 variants like the cCA, 7308/E188CC...

I'm sorry to hear of your troubles, Mike. Across several tube systems, the only issue I've ever had was a coupling cap in my tube preamp went to the afterlife and this resulted in a completely covered warranty repair. But it was the first repair of that type that the NA head had seen. So, it...

RFI Mitigation. I'll do a thread on it eventually.

Correct, there's no decimation occurring in the Qutest. I.e. you're not losing bit depth going from 3v to 2v to 1v. RW has explained that he does the attenuation in the FPGA and that bit depth resolution at output is exactly the same for all 3 settings. I have used the 1v setting for years and...

In stock form, it is very sensitive to the quality of your local mains. I've heard it in 3 different grids across two US States and, with the OEM SMPS, the sound quality in stock form can vary quite greatly in my experience. It could sound slightly thin and etched. But not always. Late nights...

Answer: Plixir Elite BDC Power supply with Statement DC Cable or Ghent JSSG360 Gotham GAC4/1 UltraPro DC Cable. Audiowise SRC-DX. Dual-BNC into the Qutest with the HF and LF filters from Thor Labs, MiniCircuits, or Audiowise. HQP -> USB -> SRC-DX -> Dual BNC -> Qutest. Upsample to 705k/768k to...

Oh not trying to push you either direction. But early tube failures are just a bummer. That's all. 👍

Did PS Vane ever get the QC issues ironed out from a few years ago? I nearly bought a pair of ACME 845's, but a buddy had a tube go dead on his Cary amp (he bought from Grant and was taken care of), then Grant stopped carrying them altogether, and I honestly stopped paying attention to the...

I've compared recently to some Linlai Elite 845's: https://pinkfishmedia.net/forum/threads/linlai-elite-e-845-moly-plate-tube-review.290782/

Canare is the only maker of BNC->RCA adapters that are true 75r. And they have been discontinued IIRC. On a Laird 75r SDI BNC cable, the Canare RCAP adapters do indeed test out at 75r. As far as an RCA connector being true 75r, I'm not aware of one, though if it does exist, Canare would likely...

24 hour check-in: Getting really fun. There is a newfound ease and inner-illumination that absolutely rivals the best 300B amps I've heard (calling out Audio Note, Jadis, & Shindo here...). Any sense that you can localize the speakers at all in 3D space is gone. Even when you're looking right...

I have no understanding of what the physical drivers are here. Wouldn't even hazard a guess. But, yes, fun is being had.

I think you're close, but not fully correct. I have been watching this for over a decade and the dichotomy seems to be: A) Measurements are a proxy/replacement for what we hear. B) Measurements are to be considered, but are not a proxy/replacement for what we hear. Many objectivists at ASR and...

Reserving for future observations.
