Hi Charles.
The Franks are exceptional amps....but the choice of speakers, Soliloquy 6.2 with its impedance curve is a perfect match - better than the match of the wavelengths for example.
Then speaker positioning, room tuning, trying out numerous power cables, interconnects, speaker cables, digital cables and of course tubes - the ACME's are great - and the TS brown base black glass are so musical and revealing!
I have spent much more - Wavelengths, Devore speakers, Elrod cabling - and have less organic, musicality because (I suspect) the sum of the parts were less complementary.
Cheers,
P
