I'm new to the forum, having just gotten my old equipment out of storage. I'm looking to upgrade amp, speakers and tt, for a straightforward modern tt-based system. I'll probably get a project debut tt to start w, and was looking and reading about the rega brios for a nice affordable int amp. There seem to be several versions available used, and wanted to know if there are significant differences between them I should consider. There are currently 3 on ebay and ebay.uk that will go for a little under 200, yet they seem to be the early versions, as they don't have a number after the brio name. Should I hold out for the brio 3, or are the differences relatively minor? ALso, how much should a brio 3 go for used? Thanks in advance,
