Goldmund mimesis 9.5 and Wilson system 8

Would you give the Goldmund the nod over a Krell 700?

I can also demo the mimesis 9.2 as well, though it has some scratches etc... Thanks for all the advice. I am to take it that there are soem reliability issues Goldmund?

My experience is that Goldmund makes great sounding amps that will need more regular and expensive service than a 1970's Ferrari

That is not the answer I wanted to hear. I live in Japan and anything of this sort is a huge hassle, not to mention twice as expensive.

Reinforces my sense that I should buy off here and have shipped to Japan..especially with the Yen at 83. It is very difficult to audition gear hear due to traffic and japanese customs. Thats why Im trying to go to those who know! what would be a good fit for the Wilsons. Thanks for your reply.

I didn't have any idea that audio was as difficult to audition in Japan as you recount. I was under the impression that Japan was a "last bastion" of a nation of audiophiles.
To answer your question I don't know the Goldmund Nimesis but agree with your conclusion that 5K is an awful lot to shell out for a used amp that old. The fact that it was "overhauled" speaks to either of two obvious possibilities. It's performance was compromised by old capicitors or worse, and this represents a truly miserable liablity, or a true fanatic was maintaing the amp to the highest standards. The likleyhood of either is difficult to assertain with any degree of certainty at this distance. However, you cannot discount that there is a clear downside risk.
You might want to weigh this risk against the veracity of the percieved culture of great respect for venerable gear in your country. There appears to be a strong demand for golden age hifi in Japan such as the JBL signature series of loudspeakers for instance.
