First Watt Amps

The F1 and F2 are both current source amps, i.e. the work best with crossoverless speakers, as for example Fostex and Lowther drivers. Both F1 and F2 are limited to 100 pieces.

The Aleph is a "standard" (if you can say standard for any of Nelson Pass' creations) voltage source and should work with most (efficient) speakers. There was a couple of recent review posted on Asylum and Audiogon on the Aleph. No production limitation on the Aleph as far as I know.

There is a new F3, which uses JFET output devices.

Best is to contact Mark at Reno Hifi. He does the official distribution of the First Watt amps, and is great to deal with. Highly recommended.

Restock is right. The F1 and F2 are for single-driver speakers only, the Aleph J is for "normal" speakers. The F3 looks verrrry interrrresting, but it's not out yet AFAIK. I posted the recent review of the Aleph J, and it punches way above its weight class. It's not quite the equal of my super-tweak SET amp at ten times the price, and that's one hell of a compliment to the little Aleph. It's the best small solid-state amp I've ever heard, and the only one I've found that keeps this SET addict wanting to listen for hours.

I bought mine through Reno Hi-Fi, and I second the nomination of Mark as one of the good guys.

And now for something completely different... Fascinating man, fascinating designs.

Thank you all for the kind information you gave me. I am interested in this product and sooner or later I will give it a try. I use Aleph mono amps for quite a while now and I never listened to a transistor amp which is so complete from it's spectrum. I think, it is also based on the 8 ohm load from speaker. I think, too, from reading, that the F3 is the way to go, but I have no chance to listen to ....
Any idea when they will go for a mono amp ?

Any one heard the F5 and compared it with the J?
