Upgrade


Hello,
I own the below system and I am looking for an improvement by upgrading one of the components (budget $2000-3000).

-Graham Audio LS5/8 (large BBC studio monitor speakers)
-Analysis Plus Oval 9 speaker cables
-Mark Levinson ML 23.5 power amp (completely recapped by Madrigal technician)
-Audio Research LS 5 MKII preamp (restored and new tubes)
-VPI Prime turntable with -Dynavector 20x2 H cartridge
-Parasound JC3+ phonostage

Quite standard power cords and interconnects, no power conditioner.

What change would make a significant difference? Larger soundstage, more liquid, open sound without loosing the dynamic punch?

Thank you for your time and I would appreciate any ideas.

Single most noticeable ositive change I ever experienced was when I first put in aftermarket mains cables for the stockers. I use Triode Wire Labs. 
Rogue RP7 with a Musical Fidelity M6s PRX.  For new gear, on your budget I think that would be pretty fabulous.
