This is the highly regarded DNA-1 power amp., underrated at 150 wpc, actually about 175 -180 according to Steve McCormack and many audio reviews. Output 50 amps peak per channel with a gain of 32.4 dB, one of the highest gain amps made at any price. This will drive low sensitivity speakers or power thirsty Magnepans at ease! This amp is in good condition, all lettering perfect with only a few small scuffs and miniscule scratches less than 1/4" and mostly on the top edge of the faceplate, barely noticeable, see the pics. Guaranteed to work otherwise sold as is because of age. Does not have original box or manual. I have sold lots of my personal equipment over the last 7 years on Audiogon but I only sell local hence the no reviews, I am not a reseller. Local pickup in Central FL only. CALL or text 813-263-4436 and thank you for your consideration.
