Ugrade-itis - is there a cure?

There is no cure I am aware of, nor should there be. When you are done you are already "six feet under", in a manner of speaking.
As for the expenses, many other things are just as or more expensive. The trick is to be able to keep it under control, this doesn't mean stop.
I keep hunting for best pressings too.

I will put other arguments aside, and I do have them, one point, I think, is that none or almost none of us has a truly reference system. It is not that it only exists as an elusive hypothetical ideal, there are real reference level set-ups. But we don't have them. Many have very good, even excellent sounding systems but they are not that good. Examples could be that you don't know what a turntable can do until you hear Continuum, and you don't know what transistor amp is all about until you hear Gryphon top separates, and you don't even know what your current system is capable of until you get Studer open reel deck and play quality master tape dubs. So, I am not interested in 'cure' but nor am I obsessed with this stuff. I upgrade rarely and try to do it in as big steps as I can afford. Illness is under control, it would be so boring to be perfectly healthy.
Bill, watch it..
