The whole VR series is very "bright". A little too bright for my likings since my ears seem to be very sensitive to the high frequencies. Thats my personal preference, not saying they're bad speakers at all. Whatever makes you happy.. but I also have noticed the recent onkyo products to have bright characteristics of their own. The full onkyo lineup this year seems to lack some power for dynamics and it seems to be very bright. That being said, i would think that linking VR's and Onkyo together would be a treble machine. If thats your cup of tea, go get your deftones CD and enjoy
If you don't enjoy alot of tweeter i would perhaps look into anything else than Onkyo, INTEGRA or sony recievers this year to match with the VR's.
The VR's are a very efficient speaker as well so you don't need a ton of power.
If you're looking for good clean 2 channel power, I have just recently demo'd the Marantz PM7001 and found it to be a very good sounding amplifier and this would be an excellent choice to match up with the VR's. (i demo'd it on Bostons, Deftechs, energy's, NHT's)
Yamaha would be a good choice for HT, and if you want a well balanced sound my personal preference would be NAD.
It's really all relative to what your acoustical goals are and your piggy bank.
my 2 cents.
