Hi Flecko, in answer to your Qs:
Are there any new candidates on your list?
I haven't really looked into changing any hardware for a while now. I still love the idea of listening to some Swiss amps though - FM Acoustics, Soulution and Dartzeel. But with the prices that these command, it would be just listening and not buying I think.
Are you still happy with this amp?
Yes, I still very much like the Sanders Magtech amp. It is the smoothest transistor amp I've ever heard and, as I've alluded to before, just works so nicely with the Quad electrostatics. I strongly suspect it would work well with other speaker types too.
You did not mention explicitly the differences to the Pass Aleph, was the Magtech so much better?
I actually never managed to compare them against each other - I sold the Aleph4 a few days before the Magtech arrived. But if I could have only kept one, it would have been the Magtech. The Aleph4 was such an interesting design (100W transistor single-ended class A) and sounded really, really 'nice'. But it was just too much of a heat-generator for me to be using as my main amp day-in, day-out.
In summary, I'm very, very happy with the Magtech.
HTH.
Mani.
EDIT:Sorry, I forgot one of your Qs:
Do you know if the Magtech is a real balanced design?
You may have to contact Roger Sanders for the official answer, but I don't think it is. I say this because Roger recommends using the single-ended inputs to the amp and not the balanced inputs. If it were a true balanced design, I suspect this recommendation would be reversed. However, in my system, the amp is dead quiet and sounds wonderful via its single-ended inputs.
