Krell KSA 50 vs. todays ss amps?

Hi
I already found a KSA-50 mk i for sale, but i am wondering if i should wait to get a mk ii amp, which is why i would like to know what the difference between both models is.
Thanks

Yuri, Read the reviews in Stereophile on line about the KSA 50S - they describe the differences between it and the original KSA. It seems that the reviewer thought that the original was a warmer and more rounded amp, more musical if you will. The KSA 50S was a bit more hifi (my terms). Anyway, read it.

Hi
Yes, i did read the reviews of the KSA-50 vs. KSA-50S.
But those are two completely different amps.
I am trying to find out the differences between the KSA-50 Mark I and KSA-50 Mark II models.
Thanks

C123666: Abe Collins owns a Krell KSA-50S, which is not what i am looking for. I am looking for the original KSA-50 mk ii.
Thanks anyway.

My recollection is that the Mk II had some changes made to it to make it more stable--I think if you shot an e-mail or made a call to Krell they could probably tell you pretty quickly.
