Today I picked up my Consonance Ref 40 along with the ShengYa CV 1 preamp. My system consists of a TTWeights Gem V2 turntable, Krell MCX350 FPB mono blocks, Raysonic CD228, B&W 801 speakers and Bogdan Audio cables. This Ref 40, ShengYa combo has finally brought out that 3D soundstage that had been eluding me for years. The highs have a nice sparkle that is not irratateing to my ears...Krell + B&W 801's metal tweeter = high end squincing from time to time. No harshness now, loud 1/2 cranked or mellow low keyed listening. The bass really tightened up and is a little more pronounced, which I like. No need for a seperate sub here! Have had Bryston BP-25 pre, Antique Soound labs pre, Audio research LS 25 Mk11 pre and none of these produced the none fatiuging and 3D sound I have now.A proffesional reviewer I'm but this combo definately took my system to the next level! I'm finally gonna enjoy my music instead of looking for that next best piece of gear..Satisfied in spades! Can t help thinking of how this will sound with those Psavane here I go again...I gotta try ways, Ian and Rachel are rock solid, hard core audiophiles that know there stuff. Sure glad I listened to thier recomendations.. Thanks for the awesum products, definately a lot more bang for the buck. Cheers Derrick.
