I have a couple of simple questions, but the background is a bit complex so bear with me. Current stereo components are TAG DVD32R/AV32R/Chord1200C. The system is used 2/3 for stereo and 1/3 HT. Ive always assumed the weak point in this chain was the DACs in the AV32R, rightly so it seems. The long term plan is to upgrade the TAG to super SHARCs and the better DACs, but most importantly the analogue bypass. Then get a proper stereo DAC for the main channels, most likely the Chord DAC64. But all this will have to wait until next summer when the SHARC upgrades are available and I can live without the TAG preamp for a month or so. Meantime opportunity strikes and my dealer gets in a second hand dCS Delius DAC. This also works as a preamp so I took it home for the weekend to test. Ill avoid the temptation to wax lyrical about this box, suffice to say it is definitely not going back (my girlfriend quickly dubbed it the dCS Delicious, quite apt). So now Im stuck with two preamps, no bypass. The DVD32R should handle this as it has two RCA digital outs, just a new cable required. But the amp interconnects are a real drag as I have to swap between the two preamps dependant on which I want to use. Apart from anything else this isnt good for the jacks on the boxes. So I had an idea. The Chord amp has dual inputs, RCA and XLR. The TAG uses the RCA, but the dCS includes XLR. I could connect both preamps at the same time if I got hold of a pair of XLR interconnects. So to my questions: 1/ Does this work at all? Is there any chance of some kind of feedback loop between the preamps causing trouble? 2/ At some point Ill mess up and the inevitable will happen; both preamps will send a signal at the same time. How is the amp going to react to this? I know someone is going to suggest some sort of 2:1 junction on the interconnects, but this basically amounts to the same thing (doesnt it?). It also has the major drawback of possibly negating the benefit of some expensive interconnects so Im not keen. Any relevant experience or bright ideas? Thanks for any input. Jeremy PS: I suspect Im displaying my ignorance of DSP technology here, but has anyone managed to get one of these dCS boxes to process a stereo signal from a (film) DVD?
