I don’t get the affection for the Adcom GFA555 amp. I had one in 1990 with one of their preamps driving Vandersteen 2CI speakers. I always felt the sound of the Adcom amp was grainy. I moved on to a Classe Ten amp which was in a totally different league.
Audio Research D240 mkll vs Adcom GFA-555
Hey Folks, I currently have a modified Adcom GFA-555 but have the opportunity to purchase an Audio Research D240mkll. Will there be a significant increase in sound quality? Speakers are Sonus faber Chameleon B's and source is Tidal through a Project Pre Box S2 Digital (as preamp).
