Ditch the Spectral.... Try to get vintage EKSC 2a versions in monoblock iteration.. These are of the legendary Jon Iverson fame amps... Still to this day, few solid amps can touch them for the treble delicacy and bass slam... I believe eagle audio in Kansas still able to supply a freshly refurbished pair. I think configured in mono they are about 2 grand. Just try to get 2a version, they are best sounding ones among three version. We had comparo session awhile ago at my friend's set up here in NY and the stereo version of the 2a in my non humble opinion (and among very experiences music nuts who were present there) it handily bettered Spectral and Levinson amps that my friend had intended to purchase. Now a pair of EKCS are his summer amps , his winter amps being Tube Research Labs 400 (those are among top 5 amps), just to give you a point of reference. Short of custom designs, I doubt many solid state amps can better them in dynamics and slam, etc., regardless of price... Don't be tempted by the larger 7 versions, those look great but are not as good, although still better than Spectral I d say... Ditch the Spectral preamp, and try to audition the Croft 7R preamp with separate regulated power supply. The British pound/$ is favorable now so you should be able to get a decent deal from England. The US distributor overprices them by alot here, but Brit dealers will deal and provide units in US voltage...
