Best midrange on a high current SS amplifier

You could give the Blue Circle BC26 a try.
It fits the bill, for everythi9ng your asking. I think you will find it works quite well.

Here is a review:

Thank you for your responses so far,

Essentially I need the imaging to match or beat a Classe DR-9 and the dynamics to match or beat a Bryston 4B NRB.

Budget is $2K on the used market, hopefully substantially less.

I can split amplification of the line source into two parts and biamp it (it is composed of smaller units) with one stereo amp per side - in which case I would need either 200 WPC into 1.5 ohms (about 50 WPC 8 ohm rating) or 150-200 WPC into 6 ohms (about 200-250 WPC 8 ohm rating).

My current setup:

Triamping with active crossover

Bass: Crown 5002VZ 2500 WPC at 4 ohms WOW bass. Not good for anything else unless you have the most laid back of speakers - due to thin "pro sound" high frequency heat. Grand imaging though.

Mid: 300hz to 5khz Classe DR-9 Great imaging, wonderfully full and nearly lush upper midrange (with good PC) lacks some dynamics. Images more specific and stable than with Bryston 4B NRB)

Bryston 4B NRB imaging not quite as good. More dynamic than DR-9.

Treble: Classe DR-9 smooth and extended, but a little thin clearly outclasses Bryston).
Bryston is smooth (with PC - stock cord is a joke) but heats the treble as output increases

I would try a Belles 150 Reference. I use a 150 HotRod to the drive my Maggie 1.6's without a problem.

Schussor - Sim Audio Moon W5. I see them go for $2500USD used all the time. Read the reviews on the internet. Email me if you have questions. I also own a Bryston 4B-ST and I had a pair of 7B-ST in my home for a week audition before I bought the moon.
