I love mine. Ths is the best, and most flexible, First Watt amp I've had--to include the F3, F4, F5, J2, and an Aleph J clone. A hint of warmth and great clarity without becoming brittle.
The often unmentioned thing about this amp is the size of the soundstage. Surprising for a ss amp.
I would not recommend using it with speakers under 90db. If you do, you wll need two for a monoblock configuration. Interestngly, that sound is just a little warmer and more tubelike.
If you have a statement or near statement preamp, tthe F4 is an HUGE sleeper.
