@tcutter I have some thoughts on this subject. Over the years I’ve used these streamers:
Auralic Aries
Sonore microRendu
Aurender N10
Innuos Zen MK3
Innuos Zenith (latest)
Lumin U1 Mini
Lumin U1 with X1 supply
Lumin U2 mini
Lumin U2
Playback Design MPS-X
Direct PC over USB
Servers have been: Roon Core hosted on NUCS(ROCK OS and Windows OS), Windows machines of various classes, Roon hosted on Innuos, Nucleus One (latest), Melco basic one (forget the model)
DACS have been: Meitner MA1v2, Meitner MA3, MSB Discrete, Chord Cutest, TT2, DAVE, Mojo2, Bricasti M3, M1, M21, Denafrips Terminator II anniversary, Moon 791,Playback Designs MPD-8
SACD Players: Luxman D08u, D03X, Marantz SA-10, Accuphase DP-770 (latest)
Switches/gadgets: Various Netgear, SFP cages, USB reclockers, Ethernet filters, linear power supplies, $$$ eth cables, Melco S100/2 (latest)
What I’ve noticed, in terms of rank from biggest to least, impacts on sound quality (1 being most important):
1) speaker room integration (a sufficiently capable speaker is assumed)
2) Amplifier
3) Preamplifier
4) DAC
5) Streamer
6) Cables
7) Network accessories
These are digital only observations. Vinyl will have its own set of tradeoffs.
My latest digital front end, Accuphase DP-770 SACD player with USB input option and fed by a cheapie $300 ifi Zen Stream 3 seems to leave nothing off the table in terms of resolution, transparency, functionality, ease of use, audio performance, etc. I’m reasonably sure to improve on say noise floor to get blacker blacks, would require a huge outlay for say something like high end Aurender or Lumin. But to me I see no value in that play whatsoever. The DAC’s noise and jitter rejection over its USB port is significant to the point that I see zero reason to invest any further on improving streaming. The SQ is very close to the primary purpose, which is playing CDs and SACDs. In a sense I’m both shocked—and not, at this result. I think the USB implementation DAC side, is super critical and pays dividends in the end. I am using a Wyred4Sound USB Reclocker on the iFI and feeding the iFI LAN port with my Melco S/100 which hilariously cost a few X more than the streamer, so these accoutrements might have something to do with it.
In any case I think uber $$$ streamers are fine and should cause no harm, but this latest experience has proven to me that they are NOT necessarily required to unlock glorious sound.
As always YMMV :)
