best monitor speaker under $2000

Check Tyler Linbrook speakers in Agon. You may be lucky if the sellers are nearby in local pickup distance.

Listening's not going to do you any good if you're not listening through your Rotel. The Rotel is very difficult to match with speakers IMHO.

What do you mean by monitor? Do you mean stand-mounted speakers?

Of course you should listen to lots of speakers. We all should.
But, if you can't and you want a suggestion (seems that's what your looking for) I suggest the Gershman V-1s. I use them in my living room with a Denon receiver and hear excellent tonal balance, very good soundstage and engaging music.
You will need good stands- Altlantis is what I use.
There is a pair for sale on Adgon at $550. Not a bad price.
If you go there, demand that the seller ship the speakers in separate, very well packed boxes. My speakers were dinged up because the seller shipped them in one box.
Good luck.
