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.

I recently purchased a Primaluna Dialogue 1. A nice, feature laden, well built integrated that is fun. To get the warm full sound you must get out of the stock tubes. I fooled around with various tubes, a snap since this unit self-bias, plus accepts many different tubes so you can tailor your sound. The KT 90s will give you a big warm sound; but the tube I chose was a NOS Russian tube 6N3C-E also known as a 6P3S-E recommended by Jeff Day of 6 Moons and Positive Feedback, read his blog on this tube. It costs only $65.00 a matched quad from Jim McShane, one of the best tube guys in the business...also, I tube rolled the 12AU7s and settled on an RCA Clear Top Side Getter. The 12AX7s are now Sylvania Black Plate with gold pin 3 mica. Wow! Warm, full, detailed, great top end but no screechy violins, huge layered stage, wonderful tone, timber...almost lush, but not quite with my Tekton Lore, very dynamic as well. Read Joe's Tube Lore, it really helps in tube direction .
if you really like "ruler like response" I doubt you'd like tubes. tubelovers relish the "inaccuracy" presented by tube sound.
Desalvo55:
I will offer an alternative to amp replacement and throw out the notion of trading within Tyler Acoustics' line to the full-sized Woodmeres. Providing your room is large enough to utilize a speaker of that size, you might find that the relaxed, natural sound of the Woodmeres is just what the doctor ordered. I really like mine for many reasons, but the overall tonal sonics is a primary one.
Just throwing my two cents in here...
If you like the PrimaLuna sound, I would seriously consider the Dialogue Seven monoblocks provided you don't need balanced inputs. I have owned two of their integrateds (prologue two and dialogue two) and enjoyed them a lot. In my experience, the only thing that was missing was a bit of grunt and transparency, but with the sevens, you should likely have plenty of grunt and a couple of sets of Ceraballs from Finite Elemente will assist with the overall transparency as well. One other nice point is that you can work with Kevin Deal at Upscale Audio, whom I have dealt with a handful of times and he is always strait forward and does what he says he will do.
