I just picked up a V16 - needed a smaller amp for some things - I'm looking for a schematic for the preamp - I found one for the V32 - are these two amps built with the same preamp. I've read quite a few searched posts and have not found that particular answer. Any helps would be appreciated. Any comments on modifications to increase headroom, etc, would be appreciated as well. Any recomendations regarding favored speakers for this rig would be appreciated too.
