@john737 I have been at this digital game for 5 years now and no longer bother really with my legacy CDs or vinyl, I am 99% streaming.
But it has cost me $$$ to learn the following:
1. Buy a good streamer like Aurender or Innuos or Grimm etc
2. Buy a good DDC with internal or external LPS like a Singxer SU-6
3. Buy a good DAC with a proprietary USB input module alongside a host of other input types like BNC & AES, like a Denafrips or Holo Audio or Lampizator or Sonnet etc
4. Buy a good ethernet switch with a OCXO clock inside and which has an internal or external LPS, LHY, Melco and Nordost make good ones
5. Buy good digital cables like Shunyata or Furutech or AQ etc
The upshot is every link in the chain matters sonically and synergistically to one degree or another. Case in point, using fiber optic in the chain like I've done after getting a Lumin P1, which made a fascinating, VERY noticeable impact on clarity, separation and soundstage.
Finally, one last piece of advice - disregard anyone who chimes in on this thread with a "bits are bits" claim who has not spent serious time and money on optimizing their digital playback system... they don't know what they are talking about.
