Yes, I am quite satisfied. I have no plans to ever upgrade my speakers, amp, preamp, sources, and most of my cabling. I am happy with all of it.
I still need to address power issues, room acoustics, isolation platforms, footers etc. So I am not done spending money by any means, but the main components are firmly entrenched and not going anywhere.
I can definitely see digital source equipment improving over the years, so I won't rule out an upgrade there at some point.
I will also continue to tweak, probably forever, who knows for sure?
