A great day! Day off, Payday and a new (22 year old) amplifier!
Adcom GFA-545 II, 100/100, samples on several sites measure above 125 watts per with 120 Volts AC Line.
So far I've played about 4 hours, mostly on the 2Pi Towers and know this will be my first keeper solid state amp since a Muse 100 in the late Eighties. More than 20 times the power of my DIY 6550 Single-Ended is a revelation: iron-fisted control of the bass which takes the bungee cord bass of the Alpha into JBL territory (only deeper) and imaging that astonished me from the first note.
There's little or no grain in the treble or else my ears are finally old enough not to hear it
The only negative is I never found myself thinking, as I often do with my tube amps, "that really sounds like a string being plucked", or some such reaction to a note or phrase. OTOH, the kick drum on "88 Basie Street" really sounds like a skin being thumped by a mallet and not just a ker-whump in the general direction of the percussion as it usually does.
Sunday I'll finally get to put the shunt resistor on the DE-250s and hear what the 4Pis sound like with the new horns. Stay tuned.
