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.

Twas 20 years ago I heard the Theil 3.6 with the VT-100 MKI and it was absolutely awesome playing Bonnie Rait, the ARC sure drove their relatively difficult load - good enough I remember it 20 years later.
I was very impressed Pubul57 at how the mkIII drove his 3.7's. One hell of an amp.
ARC and Thiel are a match made in heaven. I have spoken often of the time I heard that match.
After reading all this I think you should really get a pair of NOLA speakers and the Prima Luna mono blocks with rolled NOS input tubes. You may even want to try rolling the outputs depending on whether you overshot the warmth target you are aiming for. It is clear that's what will do it and you even know from personal experience what the sound of that combination is. Why fight it?
I forgot to add that you should recable with an entire loom (all cabling) with Cardas Golden Refs or similar Cardas copper cables. Everything will be nice and "toasty." I am quite serious, I think you will love it. For inputs use 50-60s Mullard Blackburn longplates if you can get them. For 6SN7s I would think Sylvania 60s Green lable GTBs will be a good choice but there are many other excellent choices, just picked a reasonable one.
