Shindo and synergistic components

I know many Shindo enthusiasts are in for the whole system - pre/amp/speakers. But for those with just a preamp from Shindo, what amps are you using with it? I'm particularly interested in higher power amplifiers (ie 60wpc +).

Or if there are owners of the Shindo Sinhonias (40wpc I think) - what speakers are you using?

I'm considering their pre amps, but their power amps may be a touch short of the power I'd like to have, so I'm exploring synergistic high power amp matches with the Shindos. The preamps being considered are the Monbrison or the Masseto.

Cheers
