OK guys, I ended up keeping this amp and selling the other amp (F5) instead as I preferred the sound of the AlephJ. I'm a very practically minded audio guy and just didn't want to deal with the heat this thing puts out so I've been looking for a replacement and finally found one so this is up for sale again.
For those of you interested, I replaced it with a Belles 150A reference, and no, it's not THAT much better than this AlephJ. The bass is more articulate and tighter, imaging is better, and the overall presentation is less 'lively', darker, but enjoyable. It is slightly less detailed and doesn't quite have the body and sweetness of this amp. These are the very same reasons I chose the AlephJ over the F5.
Comparing the two amps head to head really gave me a newfound appreciation of the value this thing provides, but as I said, it just runs too hot for my taste. I run my stereo for 8 hours everyday and class-A is just not all that practical for me, let alone tubes
