Considering the speakers, you are not in the esoteric price range. Not trashing them as I am really amazed at their price point. ( I have D5.1's in my shop powered by a V3) Really, don't know how they do it.
So the amp is not that critical. Look for a solution with the best internal DAC and streaming software. Unfortunately some very nice integrated amps have $5 DACs in them. Even the Moon internal DAC I would not write home about. To go external DAC and maybe IOTA integrated? If going to better speakers, the Hegel, Atoll, AudioLabs integrated are all exceptional. I put them a notch over Rega, Naim, Linn, Cambridge, Marantz etc. Ones I have heard. I have not heard a PS since the first generation when I lived in Boulder. PS does seem to make some very good electronics, but I just get a bade taste with the snake oil they also push.
My desk is a PC as server and streamer. I run JDS Atom+ DAC and preamp/phones into a Schiit REKER driving my Vifa/Dayton 4 inch mains and an 8 inch sub. Once I tuned enough JRiver parameters, I have eliminated the vocal sibilance I am so sensitive too. It plays more than loud enough with all of 2 Watts. I tried my ELAC's on it and sorry, as good as they are, they were no match for the Vifa XT-25 tweeters. Electronics under $350! I really want to hear an Aries II in the system. Now, I only listen to headphones occasionally at night. That is not my primary listening, but the $109 JDS seems fine. I also have an Asgard. Can't tell the difference.
If I were buying a desktop from scratch, I might start with Sonas Faber Lumina IIs, go for the bigger 12W Schiit amp, Probably a JDS Element DAC, maybe WiiM streamer. All that way less than the above mentioned prestige brands and I would match the sound any day. Maybe the RME DAC instead of the JDS. Not sure it is smoother sounding, but the feature set is worth the price.
