@thielrules, Yes Aries Cerat preamp and monoblocks is in another league paired with the 3.7s, it is even more musical and engaging than the Ypsilon pre-power.This level of musicality is impossible to reach with SS.If you are ready to spend 46K and cope with size and weight of the gear than i would recommend Aries Cerat no question.Regarding myself i have not yet made a decision between Aries Cerat and CH Precision, the later one being much easier to live with, not heat and the gear is totally future proof.I cannot afford to make a mistake because here we're talking 80-90K worth of pre-power.This will be my end game system.
