Hello. I have super nice D300 for sale. I bought it locally from the second owner who got it from a friend of his. It's in spectacular condition. I can't find any visible flaws other than a few marks on the binding post nuts which is typical for these amps.

This amplifier has never been serviced or modified. Completely stock. I am an electronic tech by trade. I carefully removed the top cover to do a visual inspection. Everything looks great. All of the electrolytic capacitors look perfect. No bulging or leaking anywhere. This amp was used on a regular basis so the caps never had a chance to deteriorate like ones that sit for too long. Truly one of the finest D300s I've seen.

I've had 100s of amps and I can say this is one of my favorites. It has effortless power with 16 output devices per channel. It's rated at 160 WPC into 8 Ohms and 300 WPC into 4 Ohms but I believe that's very much underrated. This amplifier digs deep into the music and gives you magical imaging and sense of space. I experienced the music on a much more emotional level, more than most amps I've owned. It's truly a special amplifier.

I have the original box and packing for safe arrival. Let me know if you have any questions.
