Hello everyone,

does anyone know the Bulk Pure Enhanced Technology from Teac or Esoteric?

For example: Teac NT-505

Thx

See if @Henry_McLeod @Johannes_van_Leent have experimented with it from Windows.

I haven’t I’m afraid. I’ve used the NT-505’s streaming interface exclusively, and in the few minutes I used the USB input it was into a Linux (ROCK) powered machine to confirm it would connect as DSD512 which it did.

Until now I haven’t. If I remember well, I have only Teac HR Audio Player and Lumin streamer once or twice (once to check the firmware version of my NT-505). Both did operate (checked only a few minutes), but nowadays I use ROON (and Qobus and Tidal within ROON), ROON ROCK. Mostly I use the streamer, but the USB connection to Roon Rock operates correctly.

Any new takers on this tech? It’s a bit dubious, as i still need to utilise a Windows PC (i think) as the USB host.
I tried the tech about a year ago, on my then guest Soulnote D-2.
My take away was that it was good, but i got similar results from a low latency isochronousUSB transfer (std, only set latency lower).

My host was, and is still, a headless/fanless Win 11 Roon Core and Minim2 server. It has got an SOtM txUSB Ultra PCIe card, separately powered by a linear 9V PSU.

I recently bought the Soulnote and intend to re-visit this tech/method. I have had significant and important improvements with a dedicated Diretta link to the same USB input on the Soulnote, so i figure there are still things to optimize for USB transfers!
