Lots of great choices in that price range used that can drive efficient speakers. Assuming that the D1s impedance curve is reasonably flat, w an 8 ohm, 90 dB speaker, you could use OTLs or transformer coupled. I can only tell you the amps that I have used and enjoyed that fall into that range include VAC Ren 30/30, Atma-sphere M60, Joule VZN-80, and Doshi/Lectron JH-50. You could go higher up the food chain (of all but the Jh-50) than I had. I will say that the Joule is probably the warmest in my system and the Atma the quickest. Music Reference RM-9 is reputed to be a great amp also but I've never heard it. Since your current rig is v high power you way want to consider higher wattage models from these line-ups, like the Ren 70/70 (or monoblocked 30/30s) Atma M-1 or Joule VZN-100 monos. Be forewarned, the OTLs do run hot, the Joules very hot!!! so if you have kids or pets, that may be an issue. With the exception of the Joules, all of these typically are in high demand on the used market, so you could try one and move it along if it didn't work for you.
Tube amp decision - Thoughts
Looking for a synergistic connection. I have, IMO, a very good setup. But I believe I errored in one important aspect. I always wanted a ruler flat response. I believe I achieved that. Great recordings sound great. But the majority of recordings seem to sound a bit thin in our system. Not to others audiophile types but I have to admit now that impact has got to be part of the quotient for greater enjoyment.
I have a pair of rather efficient Tyler Acoustic Decades. They sound very accurate as they're reputed to be and most folks run tube amps with them, perhaps to warm them up a bit.
My system consists of a Pass labs X350.5 which has played stellar through Dynaudio, MBL and AV123 Line Arrays.
An Allnic L3000 preamp really makes this system sing in 3D.
Sources are a VPI Scoutmaster and a modified Oppo BDP83SE backed by a BDP95 in stock form. A lot of attention has been paid to my AC.
It's all well and good but my family and I feel that it lacks impact and warmth with a lot of "modern" CD's or streamed FLAC files. I have Def Techs in our TV room which having built-in subs are pretty fun to listen to if not so transparent and refined. But it did drive home a weakness (perceived)in our 2 channel setup.
Having visited many audio shows, my wife and I always seemed to love the rooms with Prima Luna Dialogue amps playing in them. Of course they are generally partnered with NOLA speakers. That seemes to be an amazingingly synergistic combination. Rogue Audio amps as well seemed to captivate us. But there are a lot of great tube amps out there. Thus the post.
I'm going to build a pair of LS-9 line arrays. I owned the LS6's and sold them some time ago. These are also tube friendly speakers.
So given a $5500 dollar budget new or used, where to go?
Thanks for your responses.
