More than one audio rag reviewer has stated the AR XA was their first real taste of the high end. The little table that could was my main deck for many yrs, purchased a Thorens TD-166MKII thinking to step up, the Thorens went into the bedroom system.
It wasn't until "The Rock" Kenwood KD-500/Grace G-707 came along that the AR gave up it's spot on top. This was a completely stock AR, modded they can be quite special.
