I basically have gone the same route as you except that I started out with the Haydns for my front speakers. I would suggest that you consider using high quality amps for the Beethovens especially if you use them for regular two channel. I have a friend who is a VA fan and he is using the Mahlers for his fronts, here is the good news we have discovered thru listing comparisons that the Monarchy Audio SM-70 Pros or SE-100 Delux amps are the way to go. In direct comparisons they outperformed Classe and Plinius with the VA,s. Just go to their website (and audio review.com) and check out the reviews
Vienna Acoustic Beethovens-The right electronics?
OK I admit being bitten by the "upgrade bug" I'm going to VA Beethovens/Maestro center, replacing the Bachs/Theatro center. I will keep Haydens for rears and a Rel Q-100E sub. My room is 19'x13' I'm seriously considering B&K Ref30 and a 7250 200wpc 5 channel amp OR a 305 150wpc 5 channel HT receiver and using a ref 2220 220wpc 2channel amp to run the Beethovens. The budget works w/ the B&K equip. As a side note I found a good deal on Audioquest Viper interconnects. Am I on the right track or should I be considering something else. Open to suggestions??
