Where should I Go Next?

Good response. If you are happy with what you have, why bother? If you are not, determine what you want to improve and upgrade accordingly. Sounds like you may have the audio neurosis problem. Do you like vanilla, chocolate or strawberry ice cream? Not being facetious. Unfortunately, very common amongst audio types. Why don’t you just listen, enjoy the music and be done with it. With the money you saved, take a nice vacation with your wife.

@bubinga thanks, if I were to choose one of those flavors it would be Chocolate. I would never eat Strawberry. My favorite is actually Peanut Butter.

I have always had an issue when I get into anything I go a little crazy, but I've been collecting vinyl since the mid 70's.

My old system was an Onkyo 506RS Power Amp with a 306RS Pre-Amp with Klipsch Heresy II's, a Nakamichi Dragon Cassette deck and a Thorens Turntable. 

Unfortunately, I had a period when I kind of quit listening and sold everything to build a home theatre.

I still kick myself. I lived in Japan from 1984 to 1988 and again from 1991 to 1998. I got all my equipment for an incredible price. I sold it all when I returned to the states.

Puritan Labs PS106 is about $1300 and also quite good.  I run one of those also. https://www.puritanaudiolabs.com/ps106/

Good hunting.

I think trying other speaker cables would be worthwhile. I'm a big believer in cables making a difference. Not that they solve all problems but, for me, they have added significant improvements in systems that already had good component synergy.
