In the $5k range for a Streamer I'd recommend the Lumin T2 or the Moon by SimAudio 280D. I currently own 280D and its a great Streaming DAC. I've been comparing it right now in my system against the Holo May KTE and the NAIM Uniti Atom. The Atom is for my office and headphone setup and does outperform the 280D by a little in musicality. It's more analog sounding and closer to vinyl. Of course both are beaten out by the May when it comes to detail retrieval but for under $4k both perform amazingly.
Also I had the Lumin U1 mini as well in my room and did enjoy it. When paired with the PS Audio DSD, it was the closest thing I have ever had in my room to the dCS Bartok in all out performance. Like so close that I decided not to pull the trigger on the dCS and wait for the new version from PS Audio before spending an extra $10k on the dCS.
So I'd recommend the following in this order only because I have had the units or their smaller sibling in my system and loved them. The Auralic I have not had but I hear great things from multiple dealers that its a great streamer.
- Lumin T2 Network Music Player - $4500
- Moon by SimAudio 280D - $3900 (More Digital and Refined) or the Naim ND5 XS2 Slim Chassis Network Player - $3999 (More Tube like sound)
- AURALiC Altair G1 Digital Preamp / Streamer / DAC - $3249
As far as the HiFi Rose; they are a new company as far as I can read and I'm not keen on buying something new right out of the gate. Who knows how long they will be in business and be able to support your gear. But it definitely looks Future-Fi in its concept with streaming Video and Audio. Something Apple should let the Mac Mini do.
