where best to spend $2-3000 upgrade dollars in my system

@bksuperphon2, In my opinion, most systems will improve if they are powered by at least one (but two or three would be better) dedicated 20 amp circuits with each circuit having its own 20 amp breaker. Would require work performed by someone that knows what they are doing or a licensed electrician.
The upgraded AC duplex outlets could be installed where your current outlets are. I prefer the Furutech GTX-D Rhodium or the Furutech GTX-D NCF(R) outlets. If you don't want to spend that much money, I also like The Porter Port AC outlet that Albert Porter (Audiogon member sells). Not to long ago I saw Alberts ad for the outlets ($41/each) but I don't see them currently, or I missed them.
You need someone with a trained ear to listen to your music with your rig to determine if you are in need of some room treatments. Or you could research the topic on your own, online.
If you wanted a tube Phono Preamp I would suggest the Allnic H-1201.

My Ohm Sound Cylinders don't seem to require much power (Carver TFM 15CB) and sound fine at low volume. I am really impressed by the "holographic" effect they produce even when placed poorly in a room. Unlike ANY conventional box speaker!

@ bksuperphon2 - I believe your cables are your weakest link!

Take a look at KLE Innovations cables
For IC’s start with the gZero3’s
For Speaker cables use the gZero6

Don’t be put off by their appearance - they put all of their R&D dollars into performance - not looks

The speaker cables may look skinny, but even the gZero2’s trounced my Van den Hul D352 10 gauge speaker cables - across the board, but especially in bass depth and control.

Their IC’s trounced my VDH D102 MKII’s - again, across the board
Their digital cable also bested my VDH spdif cable

I have compared the gZero3 IC’s to silver Kimber XLR products on a friends $50K+ system and the gZero3 came out on top

Also take a look at their power products

Take a look at their web site and read some reviews...

I have tried most all of their products and not one has failed to please.
They will allow your system to "BREATH"
