I cannot believe that I am the only one to list the VAC Renaissance as the all-round BEST SOUNDING tube pre I have ever used. Top that sound quality off with an included remote, cinema by-pass, dual RCA outputs AND XLR out, 100k Ohm input impedence and 96 ohm output impedence, and an optional phono stage to die for, even with very low output MC cartridges. Oh yeah - one more thing - VAC utilizes the tubes so effectively that the casework of the pre-amp does not need to have vent holes in it and tube life is incredibly long.
