PS Audio DAC output

Hi. The direct input is the shortest path on my integrated, the signal goes to an exclusive volume pot, then straight to the power amp (Yes, I still have volume control!). The whole preamp section is bypassed, even the normal volume pot, cause the pots are not the same.

Dear, Steve.

As a transport, I have two options:

1) An Asus notebook connected to DAC via USB.
2) I also have a Squeezebox Touch, via S/PDIF coax.

Between them, I prefer the notebook via USB. The Squeezebox+S/PDIF sounds a bit lean...

I Only hear redbook files.

Hi. My integrated is a Sansui AU alpha 707MR

Yes, sound is also fatiguing if I use the preamp inputs.

I think I figured it out. I changed the sampling rate from 96khz to 192khz and the sound became smooth and "liquid". Since it is now late at night, I have heard in very, very low volume, so tomorrow I will check in a comfortable level. Still, it seemed to make a good difference. I hope I'm not mistaken.

Dear, pmotz. Do not worry, I appreciate your help. If you want to look at the schematic, the service manual is here: https://www.hifiengine.com/manual_library/sansui/au-a707mr.shtml

My (adorable) speakers are Harbeth Super HL5 Plus.

Solved! The problem was in AC power...

Fixed and sounding fantastic now. Running Squeezebox Touch as transport > Oyaide coax cable > PS Audio DLIII DAC. Smooth, full, articulated, zero fatigue. Goosebumps! Just amazing. Thanks.
