Message-ID: <10339@uwm.edu> Date: 19 Mar 91 13:46:28 GMT Sender: news@uwm.edu Lines: 21 Approved: tjk@csd4.csd.uwm.edu Originator: tjk@csd4.csd.uwm.edu This is getting kicked around a bit in rec.audio, and it's certainly a high-end subject. IF you don't play vinyl, then it seems intuitively likely that a pre-amp box full of active componentry is less desirable than some sort of passive attenuation/balance/switching technology. Even if you play vinyl, the idea of a RIAA+head-amp box specialized for that function and producing line-level output might suggest the desirability of passive pre-amping. Or, it might suggest the viability of a truly high-end integrated amp - just a power amp with passive volume/balance/switching stuff on the front - this also eliminates one stage of interconnect - appealingly minimalist. Might even be room to save a few bucks here... I know for a fact such products exist. Anyone here using them? It said that there are all sorts of potential problems with impedance matching and the like. Feedback on that? Tim Bray, Open Text Systems, Waterloo, Ontario
