I too bought the Oyaide R-1 from Chris @ VH Audio to replace the Shunyata SR-Z1 outlet that I had been using for awhile. Man, the R-1 spanked the Z1 right out of the box!! What a HUGE DIFFERENCE!! It was like an upgrade to a higher end amp or preamp! I CANNOT recommend it more HIGHLY! Well worth the money & get the Carbon Fiber/aluminum wall plate to go with it. I"ve heard that there is even MORE to be had by using this wallplate. Read the reviews for it. Jonathan Hart
