$2000.00 to spend on new speakers.


I’m wanting to upgrade from my Klipsch RP-600M bookshelves. Budget is $2000.00. Opinions would be appreciated. 
My system is as follows:
Pro-Ject RPM-10 Carbon
Nagaoka MP200
Parasound JC3+Denefrips Pontus II
Wilsenton R8
2x REL T5i
Sonore MicroRendu
MacMini running Roon server

You should consider Monitor Audio Silver 300.  On the Stereophile recommended equipment list, and the MSRP is $2,200, so you might get a small discount and be right at budget.

Focal Aria 906 pair has been great for me. 89.5 dB sensitivity. Excellent detail, which should pair well with a tube amp, no?
Once again, a "what best speaker" thread where we have 12 different "best" speaker recommendations, many of them even after the OP bought his new speakers! lol
