Need Amp Recommendation


I'm auditioning Rockport Miras which I like, but the upperbass/lower midrange could use some weight. I'm driving them with Theta Citadels, but for fun I grabbed a VTL ST-250 from another system and tried it. It provided the midrange weight I seeked, but it suffered in other ways (highs a little closed in, bass not as tight).

Wondering if anyone has any suggestions for a SS amp with great midrange, or a tubed amp that would do better than the VTL ST-150.

Thanks.

I've owned VTL gear, & respect their products, but if you're not using tube-friendly speakers, like Merlins perhaps, you're gonna go broke, or crazy, trying to use a tube power amp with speakers that are power hungry.

I could suggest used C-J SS amps, like the MF2500A (which has plenty of power, and is very "musical"), but I don't know those speakers.
Are your Citadels originals or 1.5s? If originals, you may want to contact Theta and discuss the 1.5 upgrade, it is supposed to be significant. Just another option.
My Citadels are 1.5s. The preamp I'm using at the moment is an ARC REF 3. I don't find it overly tubey. In fact, it has leaner midbass than my mid-fi home theater processor (Denon's $6k flagship pre/pro).

I was wondering if swapping the preamp for something with more lush midrange might be a solution.

Sources are CDs (fed into Benchmark DAC) or analog LPs (VPI Scoutmaster).

SS amps with great midrange are my Parasound Halo JC1s ..
