McIntosh 402/B&W 803D Question

I just purchased a pair of B&W 803D speakers, and realize that my VTL MB 185 amps cannot drive the speakers adequately for rock music. I am now considering the McIntosh 402 amp as it has been recommended for these speakers. My question is, would my VTL 5.5 preamp match well with this amplifier? A few years ago I had a McCormack DNA 250 which had too much gain for the system (30db) and McIntosh does not provide the amplifier gain in their specifications. Thanks for your comments and opinions. I have listed some of the VTL 5.5 specifications:

Gain 20db

Output impedence 195 ohms

Input impedence 20K ohms
