Here I get very positive result to power the USB card with linear PS and save a USB cable,   USB3.0 card (NEC chip) is moved out from PC with PCI-express extension cable powered by 5V Salas reflektor shunt regulator with remote sense.   Normally USB 3.0 board needs both 5v and 12v supply...

I am another victim of the weak usb connector(as a portable user I have to plug in/out lots of times), even worse, I bought this from online as it was out of stock in north america, and they removed the S/N sticker (hate to send back for repair as it might take months), so not sure how can I get...

It saves the cost of NOS tubes, so mostly Hugo to passive speaker now.

I doubt, probably at least 90-92db, mine are 16ohm with 97db and volume knob is blur-green color.

You need to solder the speaker cable one side to the RCA male plug, just mark the speaker minus side to the outer and plus to the inner of the plug, cardas plug can host pretty thick cable. There are instructions on youtubes as well.

It works great with hi efficient speaker, I am using Hugo to directly drive lowther pm2a using RCA jack and kimber kable 4tc, it excels my single end with avvt2a3.

It's actually made by Everpro, same vendor for JPLAY JCAT USB card.

Not sure if anyone has experience with active optical usb3.0 cable, for example from corning and everpro, corning has copper wire with fiber to power the USB at the other end, hopefully these can be tweaked to get both side isolated.

I noticed this when driving speaker directly with regular volume, it only exists when there is no music playing, originally thought was my setup with jriver+jplay in dual PC mode.

Any idea chance of groupbuy?

Both DAC are directly connected to mothaudio Si2A3 with AVVT 2A3, it may due to the signature of the amplifier, while kind of understanding now why lots of review claim Lampi is super on DSD (dont get chance to hear it).

Got around 300 hours on Hugo, PCM wise it's super, with DSD64 my DIY DAC with 8xDSD1794 and passive I/V has more natural sound even though it is bit noisy, Hugo is very quiet while sounds more processed.

Finally I am a new happy owner with Hugo directly driving my Lowther Azurahorn( another cost saving as I use tube gear and NOS are getting more expensive), I was wrong for the difference between Jriver live-converted dsd128 and native redbook, they are almost same after Hugo (it must be the...

Kind of interesting, to my ear dsd128 generated by Jriver sounds better than redbook directly into Hugo, anyone has same feeling? Mot sure how lampizator implemented in the black DSD box while original prototype was like a TI 179x chip, and I've heard with DSD only FIR is enabled in the 179x...
