I never thought an amp should color the sound but be transparent. So knowing I could return it, I gave the A75 a try. Wow, the voicing works beautifully with my MoFi SourcePoint 10 (Master Edition), and I'm keeping the A75. I would give this a five-star rating, except that it doesn't have a trigger input, which would be great with my P75.

Much Better Than Expected
For the past 8 years I've been using a Nelson Pass First Watt M2X amplifier. This is the DIY version of the First Watt M2 amp. It's a Class A 25wpc product. Given that I built it myself it's a miracle it lasted as long as it did. It recently developed a problem which I was unable to resolve. I used this as an excuse to buy something new. The A75 provides a different listening experience. It's more detailed and produces tighter, cleaner bass. The sound is less warm than the M2X. However, it still sounds full and organic, though less so than the M2X. It does not sound lean or clinical in any way. I'm hearing a rich, natural sound with tighter bass. There's also an increased sense of air around the instruments. I listen to a lot of jazz. The A75 does full justice to instruments like piano, trumpet and saxophone. I've also noticed that vocals seem a little more prominent. I'm sure some of that is down to the increased power rating. But I also think the ability of this amp to provide a cleaner, musical sound is the larger reason. Another great benefit for me is that even at low volume the sound is very satisfying. I live in an apartment, so I have to be mindful of my neighbors. Thomas provided excellent customer service. The entire purchasing experience was painless and without drama. I'd certainly buy from him again.

A noticeable step up in sound quality.
You would think it is much more powerful than75WPC. The speakers I am using are 87db. This amp drives them to very loud volumes and the sound is still clean. The amp sounds great throughout the sound range, but the bass and the punch the drums have really grab your attention. I won't mention my old amp brand, but I feel like I have taken a noticeable step up in sound quality. I am very happy with my purchase.
