Is Audio Research SP-6 considered a good model?

the arc is a great peice, put honestly your totem/plinius combo is so good, i can't help thinking you will get 'different' but to improvement. think really hard about this change, and consider that a balanced tonally accurate playback system doesn't jump out at you (refering to the tube amp's euphoric mid's). arc is great tuber gear, and more reserved than some, put play lots of big, complictated music and really scrutinize how your sysyem reacts....yes those simple recordings are gonna sound a little more holographic with the arc, but the soundstage is just part of longterm listening fun. in any case, best of luck

i also think you might be impressed by the new cyrus 8 integrated....and the new creek 5350 (both compete and control well beyond their retails) .....well within your price range, and both 'a bit' livelier that the darker plinius character. comparing may help you sort this out before commiting....the forests are great, and your exposure player is also a giant killer.
