Good amp plus an outboard DAC.
Good amps stand the test of time (DAC's perhaps not so much).
As the new version of the P3 is reviewed as being more detailed/brighter than the earlier version I listened to you might consider the new HEED that retails for $2K, or (per reviews) the Dayens that retails for $1K.
Listened to an earlier version of the HEED and really liked it (generally not a SS fan, or even a fan of some very popular tube PP amps as well).
Not up to date on DAC's (tried CAL/Bel Canto/Theta/Muse maybe 20 years ago) and know zip about HQ streaming.
This said the Sprout100 or the NAD (3045 might be a better match) should be fine/good to get the system up and running.
Only heard the original Sprout (the 100 model is said to be much improved).
Listened to the newer 3020, but with crappy speakers, so???
