Ralph, are you saying that in most cases, the "damage" caused by an IC is greater than the damage caused by active circuitry in a line stage whose primary purpose is to control interconnects?
Interestingly, I have both George's Lightspeed and your LineStage - they both sound excellent, but they are driving different amps ( the M60s with your MP3). With my other amp, the manufacturer said no active preamp would sound better than a high quality attenuator, which I always found interesting in that he is more than capable of designing a SOTA preamp, he just does not believe in them. This really seems beyond debate or proof, just try it and see what you like - it will not be resolved here:) You just have to be more attentive setting up a passive system.
