Amp for JBL 4312 SE

As displayname suggests above, the MastersounD Dueventi is a great product for the JBL. I have 4311 here and the previous owner was also using a Dueventi to run them. I’ve done the same here and it is a marvelous pairing.

The Dueventi pairs well with the tweeter and also is a smoother presentation, which eliminated some of the bloat that the JBL have in the bass.

Another 'pro' for the Dueventi is the stock voicing.  Somehow they got it right with the stock JJ 12au7 and EH el34 tubes.  This means when the time comes to retube, you can do the entire amp for right around $100.  I've had clients try to roll in NOS tubes and they've reported back very challenging work to best the stock configuration.

Any recommendations as far as tube amps go? Or is Solid state best for this speaker. Room about 14 x 14 high ceilings and no room treatment.

Aragon 4004 will do it.

D,
Finished basement, set up area is about 14x14 with drop ceiling. Very tight budget that's why I went QSC. I am looking to get more punch out of the 12" woofers. 

Thanks for your response!

What are you thinking about for the budget and new direction? And how big is your room? 
I currently am running JBL Studio 580s with a Mastersound Duventi, and the Duventi gives my JBLs excellent base authority and really helped tame the top end which was an issue in my room. 
The power ratings on the 4312 SE and 580 are the same at 6ohms and 90db, but designs are significantly different, so it's hard to say if they'd be a good match with the Duventi. However, the 4312 SE state they are rated to perform down to 10 watts, so it could be a good fit.
