Yes, AJ, I too wonder about this.... so few have said their thoughts.

Cheers

Well I was just listening to mine this morning before hopping in the car for work!

I can honestly say that it is a very pleasing amplifier to listen to. First off, the stage is really wide and instrument positioning is really good. Extremely good separation of instruments. I'm impressed by the extension in the high and mid-high and not to mention a very well controlled bass.

It is also a very transparent amplifier as most will notice. You cannot put a bad recording on it since you'll hear all the crap on the recording but I prefer an honest amplifier (transparent) than something that will do camouflage and have a loss of micro details.

Voice are just amazing on it, especially female voices just wow me almost as if the singer is just in front of me.

If I had to give it an honest rating, I would certainly give it a 8.5/10. Really highly recommended amplifier. Don't be fooled by the 50Watts figure, it shows it has some guts with finesse!

Ciao!
Do

Do,

Thank you for your measured, objective comments. Much appreciated.

8.5, hmmm, I will think on this during the weekend!!

I never thought a FULL fet amp could sound better than most bipolar SS devices, in some ways the design brief was focusses on fets an only fets. That it turns out was remarkable, hats off to Greg and Lineout!

Ciao (a useful word for two guys with first languages of English and French!)

Hugh

I can keep re-posting about my Fetzilla ... it continues to be awesome! I will second Do's comments. It is a great project and amp. I'm still accumulating hours on mine. Soon, I'd like to try Auricaps in it as I was unable to get those at build time.

Actually Hugh, I could give this amp a 9 without hesitation. My goal was not to offend you with my 8.5 score as this is purely subjective but I tried to stay as neutral as possible. And as per my post above it is a fantastic amplifier and it deserve its place in my home. More people should also have been part of this GB and build it.

I've built tons of amplifiers to date and this one is in my top 3 favorite for sure.

All the best!
Do

Could be a solder connection, OR, it could be a noisy input transistor.

Replace T1, and retouch the pcb pads across the circuit.

Cheers,

Hugh
