First Watt is on my list of things to buy. That said, I have a Nakamichi and a Threshold, both designed by Nelson Pass. Both very uniquely wonderful in what they do. Neither is best suited for my high efficiency speakers though. I'm sure they'd sound great but not a "best" match. As a lover of high efficiency in speakers, I took a different approach. I paired my speakers with a Decware SE34I.5. A massive 6 watts/channel that gets plenty loud but is wonderful at all listening levels. I have not yet heard the First Watt J-2. Wondering if you have had a chance to sample Decware and compare? I like both engineers approach and the Decware t-shirt sums things up well, "If the first watt sucks, why continue?"
