Dynaudio Heritage + Gold Note IS-1000 Deluxe

I would seriously consider the underrated Mimas. I'm using it w my Wilson SabrinaX 87dB sensitivity and love it.  It is class AB with tubes in the preamp. 280W into 4 ohms. You could even roll different tubes if want to. There is one on-sale right now below your budget, even has DAC and phono modules included. 14 days return.

@grislybutter I had the tdai3400. You could look up my sold ad on usmart. Even with RoomPerfect or whatever the name is, it won't sound as sweet and natural as Aesthetix Mimas. 

The bass of the Lyngdorf doesn't sound natural to my ears. That's after almost a dozen emails exchanged with Lyngdorf. 

@quattr0 I know Darko loves it, but I never heard it myself. Good to know!

Two more cents: the Sugden's power is Class A, and comparable to that of the Pass Int-25. Just sayin'.

I had the smaller Lyngdorf 2170 with the Contour 20s for a while. Not enough power. Ran out of juice quick. Same amp sounded amazing with Tekton DIs. Maybe the more powerful 3400 would have enough.
