I have an Esoteric Audio E7054. Same as the Diamond D7054. These amps retailed for a little over 900 dollars when new.
This amp is rated for 50 watts rms x 4 and 200 watts rms x 2 when bridged. Definitley in the top bracket as far as Audiophile amps go.
I'm selling it for 260 shipped. 240 with local So Cal pickup.
It is missing the plexiglass cover for the eq. and there are some marks on it, which are shown in the pictures. The last one on Elitecaraudio sold for 350 dollars plus shipping. You could buy this amp, use it for as long as you want, then sell it for the same amount , or more in the future.
