On the other hand, if your source doesn't control the volume then use your Pioneer's ''Pre Outs'' and use it as a Preamp.
Maybe a dumb question about preamps
I am considering to purchase Bryston 4Bst or 4Bsst. Do you absolutely need to connect them to a preamp or can they run by itself and still achieve the sound quality that they are intended to produce. If preamp needed, would it be appropriate to connect to a Pioneer Elite 52TX that I have and use it as a preamp. Thanks for your advice.
