If your shopping I would not say go that route.If you have extra gear lying about which is orphaned from systems due flaw here or there then get to experimenting.I had an Adcom 565(crummy top end decent below)Audio Alchemy DLC(nice top loose bottom)fed a Nad cdp to the DLC and from it to an Amp whose strength was top end and imaging(biased class "A" to several watts)then fed other pair outs to the 565 and from the 565 to amp which had better low end attributes.It took some tweaking cables but that secondary system rivals the main in some areas.The DlC being remote drives the 565 level as well and I just found volume setting on the 565 so low end and high match up.I get funny looks until guests hear it.Maybe luck played some part understanding the disparate components would essentially "see different". Short cabling was used from DLC to 565 to amp.
Two preamps in your system
Has anyone ever experimented using two preamps simultaneously in a system? Say tubes on top and ss on the bottom?
