I’ve been where you are. I could never settle into my “ultimate” system, no matter how good it was. So now I have an alternate pair of speakers and a few electronics that I swap every once in a while. It’s always a nice change and lets me keep perspective. It always sounds different, and usually better. After a while I put the originals back, and they always sound different, and usually better.
maybe this isn’t for you, but I enjoy it. Whatever you decide, I hope you enjoy it!
