Here’s a suggestion that will probably get laughed at, but dies actually work. I have quite a lot of gear, high end and low end. If I find myself getting somewhat bored with a certain configuration, I’ll put in one of my Marantz or SANSUI receivers and use that for a month. When I go back to my higher end gear, I appreciate it that much more.
It sounds like what you have there probably sounds pretty good and you’re just looking to make a switch because you’re bored. It sounds like a pretty costly switch though.
just an out-of-the-box suggestion. Good luck with whatever you decide on.
