"The Ref 3 and the LS25 MKII do the same function. They provide a "pass thru" for the signal from your HT processor. I've been running mine for over two years without a problem. That's the whole reason for having the bypass circuit is to allow the HT processor signal to run straight thru to the 2 channel preamp without being altered by the preamp?"
precisely my point and even though I am a cable zealot the previous comment of needing good cables so that nothing is sacrificed is also nonsense
