I have not A/B tested the Acoustic 4 against the Hydra , but I did drag home many conditioners and compare them to the Hydra 8 and V-Ray , the Shunyatas out performed the others in ever way . Silents and rhythm seemed the most prominent . I use P.S. Audio's Soloists on the power amps . I'm thinking of up grading to a couple of the new V-Ray Pro's . Even my fussy ARC Ref 3 ( tube preamp ) responded positively to the V-Ray . I think try before you buy is always essential . Have fun and good luck . MAX
acoustic revive rtp-4 or shunyata hydra 8
