Audio Research Corporation website and ARCDB website has everything you want to know...it is not a hybrid however. Are you refering to a newer version of the SD 135?
Hybrid Audio Research?
Anyone in the forums hear about a hybrid sd 135 comming out soon? I was at a dealer the other day looking at a vsi-60 and was concerned about lack of power for my totem winds. He told me they were expecting a new hybrid to come out in the next mth or so. Has anyone else heard anything about it?
