congratulations! There's no right or wrong here really. Just faster and slower.
Many tend to agree it all starts up front with the signal producer or source. Walter's dead on there. I was worried for a while.
The 'no' rack situation is too bad... but it's just for a bit. I hope you do your homework there too. it's a real aspect/portion of a system that truly does impact the sound. it took me a long time to come around on that topic too. There used to be a whole lot of "yeah, sure!" in me about so many things audio which just didn't seem to be real additive items... like wires, power conditioning, isolation and yeah, racks too.
One note you'll find here and elswhere when perusing various topics.... "Everything makes a difference."
...and it does. One of the very best moves I made to my system was adding a substantial component rack and sure wish I had done it sooner once I heard the after effects.
Until it's time for investing in a rack, there's plenty of short money solutions for isolation.... and that spinning tube CDP should have some nice footers gotten for it. there's tons of 'em out there but I'm sort of liking a cuople types.... Bright Star nodes, and Herbies Audio labs iso cups... his tube rings BTW really do work well and aid imaging... all the above items are like from $5 - $30 ea. and can be bought as you go .... herbie's also offers a 90 day in home trial of all his products. Cheap... lot's of time for audition... and a money back guarantee.... I'd call that a slam dunk for solid inexpensive gains in performance.
I'm glad you got with Walter in the end and you're on your way! Add another few weeks to the projected waiting time for the gear to run in as well, though I'd say it'll all be ready or very close to it in 150 - 300 hrs... perhaps less but I'd not get my hopes up.
Enjoy.
