First Watt Amps

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?

bump...
