McCormack DNA-125 stereo power amplifier. This amp has been modded by Bob Backert of RHB Sound Dezign with upgraded signal path caps (Black Gate) and power supply. Cost of the mod was $500.00 alone. This is, bar none, the best sounding amp I have ever owned. The amp looks good except for a few blemishes here and there. Nothing big or really noticeable but I'm being overly cautious in my description just in case you see something I miss. Rear lettering has aged in a few places. The amp performs and sounds amazing. Original box & packing materials included. Local pick up is welcome and encouraged. I will ship at buyer's expense.

Price is $1000 to Polk Forum members in good standing with at least 100 posts. Price is $1200 to anyone else.

    Damn I want this. Terrible timing though, I’m in the middle of moving, and will have to move again 6 months after this one, so the stereo is on the back burner for awhile. I’m sure you will be able to get rid of it pretty easily

    I’d like to see it stay in the family here on the forum.
