If you have a negative opinion of op-amps, listening to this phono preamp will change your mind. Whether it was the battery supply, the op-amps, the combination, or whatever, the ASR Basis Exclusive was easily the quietest phono preamp I have ever reviewed, with the exception of the $29,000 Boulder 2008 (which is equally quiet but is otherwise in a class of its own). Music didn't just emerge from the most jet-"black" backgrounds I've ever experienced with vinyl—it seemed to leap in stark relief from that silent backdrop. When I ran the Exclusive fully balanced (into the Halcro dm10 preamplifier) using Cardas Neutral Reference DIN-to-XLR and Shunyata Research balanced interconnect, the effect was only intensified. The Exclusive seemed to suppress surface noise to unusually low levels, making records I'd thought were noisy sound quiet, while allowing ultra-low-level detail to appear out of the vacuum-like blackness.
