Audiogabby,
Right on!! Symphonic Line amps DO have an awesome, grain-less midrange. I can say that w/ confidence thru my personal experience. Also, the Symphonic Line amp I have has a lot of "soul". From my communications w/ other Symphonic Line amp owners, I can inform you that this seems to be the case w/ many other of their products. I have also heard the Kraft 250 stereo & it too has an awesome midrange & has the same "house" sound.
If you are looking to spend some megabucks (I think you indicated so!) then also consider the Gryphon Antilleon Signature Stereo power amp. This beast weighs 90kgs & is 150W/ch pure class-A operation. Retails in the USA for $25,000! I heard this amp recently & it too has an effortless, natural & grain-free midrange. Plenty of bass slam too. Very musically satisfying. The cost was the only disadvantage to me.
There are other Gryphon products that might meet your budget if the above mentioned one is (well)over.
Also, consider the Swiss make - Goldmund. Also very, very expensive but is reputed to be simply excellent bar none. People tell me that once they finish dicking around w/ various other amps during their life-time in this audio hobby, they finally come to rest once they own a Goldmund! People tell me that their amps are ones to "graduate" too. I have no personal experience tho' only relating what I have been told by many others. IMHO. YMMV.
