Hi Tireguy,
Have you tried using SET amps on the DB99s? I have a suped up Sun Audio 2A3 amp and the DB99s sound awesome on just 3 watts. Pre I use is an ARC LS16 mkI.
As to the VR5s. Have you heard them? My partner has a pair and I am stupified whenever I'm in his listening room. They are tough to beat at its price range.
