Hi Erik I did try various conditioners and regenerators over the last few years to isolate the LPA from main system without solving the issue.
Less is more?
I recently changed a Preamp+DAC (Ayon Stratus) to a Preamp+Streamer+DAC (Ayon S10 mk 2 Signature) and losing one box has produced good results.
The Stratos was fed by an Auralic Aries Streamer with LPS (Audioquest Cinnamon USB) and i had to apply (via Roon) a -3bd dip at 1-3Khz to take off a bright and edgy treble.
With the S-10 mk2, I don’t need any EQ and the system is detailed without any etch. All the frequency’s are now presented naturally. BTW - Who said WWP 6’s were bright? 😂
The Stratos and S-10 are not far apart in terms of quality and have a similar house sound so it seems logical to conclude that the removal of the external streamer has made this improvement.
I now have a much improved two box digital system rather than three and whilst this may partially limit my upgrade path, in the quest for better digital SQ, fewer components may be a philosophy worth considering?
