Hmmmm,
I don't know anything about streaming.
Do you have the same source in LP, CD, HiRez Stream?
Is the LP more involving than the CD?
IOW, can you isolate the Streamer from the System Sound?
Have you considered a Tube Preamp?
Which DACs are known to be sweet/rich/relaxed?
Problem
System is nicely transparant and detailed, but tends to get bright and harsh with certain (rock) recordings and at higher volume levels.
Objective
Nudge the system towards a sweeter, richer, more relaxed presentation.
Proposed solution / first step
Upgrade to a (tube based) DAC, budget $25-40k.
Current chain
On my radar
Lampizator Pacific (or Golden Gate 2 since I heard it's more "tube-like")
Aries Cerat Kassandra 2 Ref or Sig
— What other DACs should I consider?
— Do you think upgrading to another (tube based) DAC will achieve that sweeter, richer, more relaxed presentation?
