Priced to sell! Nelson Pass PassDIY FirstWatt F5 PowerAmp (Class-A MONSTER, perfect for for K1000, or other power-hungry headphones or bookshelf speakers)
Will Ship To: Anywhere
I'm selling my FirstWatt F5 power amp. For the few who haven't seen this amp, here is a great review by 6moons, though there are MANY others.
I've had the pleasure of trying it with a few headphones including the Audeze LCD2 and Hifi-Man HE6, they sound AMAZING. That's not even to mention the fact that the on any system I've heard, the K1000 sounds the best with this amp. Currently, I'm using it to drive my Harbeth speakers and they're great.
The amp will push over 25 watts per channel in pure Class-A, more than enough for any bookshelf speakers in a large sized room.
The build is following the specs and suggested parts list by the designer with a few improvements of parts quality, including the PSU design, with an overspec 400VA transformer and HUGE heatsinks to try to tone down the heat produced by this beast (which is A LOT). The chassis I used is a heavy duty black steel chassis with huge aluminum heatsinks, originally made for Dun Mei Audio (the best chassis I found for a monster amp like this, at over $200 just for the case).
Please excuse the image quality, there is a bit of dust and my camera is highly reflective, the chassis has a few hairline scratches that can barely be seen in normal conditions.
Looking for a quick sale at this price considering the original is $3000 and mine is a better-than-spec custom!
