Single ended Power amp recommendation

Well I am stoked. I remember when I had the Sophia 845 driving my Montana.--Whith that combo- as you go thru your collection you are looking for something that will highlight what you got.---Now with the CJs in all triode and the new speakers---anything--/-- everything sounds great.---There seems to be NO-Horn-sound. I say this because I listened only to my Lowthers for the last 10 weeks.---The Q's are just amazing to me. That sealed bass cabinet puts out some serious "hurt" in bass wacks. Double bass, bowed, sounds down right menacing. I'm not the usual audophile. I don't hear all the different speaker/amps, combos. I run a Placette passive; all Syn.Reas.active-x cables. I use Celtic Silver speaker wire. I have Audiomecca's Enkainthus as the dac.-----I thought I would miss how the Lowthers do vocals.---Not a bit.----There are just so many things I love about these speakers.---One of them is I feel happy with my same old stuff driving them.---I now don't plan to buy this amp/those cables.---As I was thinking before the speakers got here.---As to how they sound compared to:---Well I only know they put my old Montanas to shame--even in the bass dept.---As I'm listening to familar stuff I hear so much more 'into' the recording-- seems all instruments have a more correct or a 'live' tone. I was listening to Elton John's Tiny Dancer. I had never noticed but you can hear the organ synthesizer playing through the whole song. Sometims at a low level; With these speakers you never loose track of it. There is just this magic with just about any kind of music.--Not just Jazz; or vocals. Old swing music ---I swear; anything shines. ------I guess you could say I like the speakers----

I thought I'd add that the speakers remind me a little of the Placette.---In that the Placette is small and light ---with a powerful wallop. The speakers are just like that.---They are light. Even the bass cabinet is light--but w/ a wallop. The top cabinet---the same thing.----My Montanas weighed 200 lbs--So I guess I used to think big bass--big cabinet. Even rap/ dance music sound great.---The R&D guys got all the right thing together.Altho the bass is there; it never lags or stands out---unless that is the way the music has been mixed--(Such as Dance music and rap--which I normally wouldn't even listen to.)

I had a pair of Quartettes for a short while before trading up to the older model of the J2001 (twin). The Quartettes do certain things that few speakers outside of big horn systems and old Western Electric 755-based systems can do. In particular, they hve a sense of energy, vibrancy and astonishing focus. This is a fun speaker that makes most others sound constipated by comparison.

But, they do have a somewhat lumpy bass response, light-weight upper bass and prominent midrange that can be problematic with orchestral music. These things can be addressed to some degree with proper matching equipment and set-up. The Quartettes are the most demanding speakers I know of in that respect. They are particularly sensitive to proper toe-in. Too little toe-in and some of that incredible focus is lost; too much and the stage collapses.
While they are rated at being something like 95-96 db efficient, they are apparently a very difficult load because so many amps I heard them with cannot control the woofer, making the response very uneven.

I know that Vincenzo, the designer, insists on tube amplification, but I've heard this speaker work quite well with the Hovland solid state amp.
