When I first started looking to by myself amp I saw those and really wanted to have one. It was way out of my budget back then (and probably is now

) so I ended up with crappy marshall MG.
I have never tried but from the specs it couldn't be anything but great really. RG Keen (one of two designers) is also a member of DIY community, nice guy.
It should be reliable, although it uses PCB, crucial components (pots, tube sockets, jacks) are mounted on chassis and not the board and connected to the board with wires. It's very important.
Being all tube I don't know why it has all those IC's lying around

I hope they are not a part of the signal path but the protection circuit they mentioned. I mean with two preamp tubes they really don't need anything else in there.
Check out the thread about these amps on DIY forum, RG Keen started it.

Btw, I like simple tube amps, all amps I built are simple without any fancy-shmancy crap inside, check this out

Back in Serbia I used pristine clean princeton clone I built with tubescreamer -> tube preamp -> delay in front of it, so clean amp is ok. Especially if you're mostly into clean sounds.
If you ask me, go for it, but only after you try it. It's not a small (and cheap) thing to buy so make sure you're doing the right thing.
