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

According to the shills for TC and SR, you can totally transform your system to “a proverbial jaw dropping experience” with any number of snake oil tweaks. The claim is that these tweaks are better than any equipment upgrade. Magically the tweaks can transform any system from a pigs ear into a silk purse.

Of course YMMV.

If the Dynavector is the high output version, this Croft RIAA at a grand would be a nice upgrade!

@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!
