I tried a friend's STX and I'm looking for something more. I enjoyed what I heard, but in no way did it match his little tube amp...at least with the 580's.I am running my 650s with the Xonar essence st amp (extra high gain 300-600ohms)...
Really? I picked up the 580's for $150 almost 8 yrs ago.I really wanted the 580 or 600 back when I bought my 595s, but they cost difference was just too much for my budget at the time.
