Thoughts on VAC preamplifiers to drive D’Agostino power amplifiers? Thoughts?

@audiobrian I've been using D'Agostino Classic Stereo amp with a tube preamp for a few years and the result is excellent, but my preamp is not a VAC. I recommend sending an email to VAC asking if D'Agostino is compatible with your specific model preamp. I think impedance mismatch is the only thing you have to be concern with.

The VAC preamps employ a transformer output that has a low impedance and can drive any well designed power amp (tube or SS).  Used my VAC pre into an Ayre VX5/20 for many years and it never had any issues while it added a little of the VAC personality to the beautiful sound.   

you would expect any top shelf preamp like a vac or cj to be able to drive any good top shelf amp

that is one of the main functions of a preamp

to be sure, call kevin at vac or dan d and ask... they will for sure know of the top of their heads
