I talked with Frank Van Alstine today, owner of Van Alstine Audio. He lives in my town and I will be going over to his house to audition some of his Valve amps and Hybrids in the next 2 weeks. He said I can bring any piece of equipment with me to his house to hook up to his amps. I wonder what he would think if I showed up with my Magnepans!
I'll probably bring my 840c along with some music. I will post a review after I audition his amps.
