Just replace your active preamps with a good transformer passive linestage (TVC), and you will probably hear the difference. Most active preamps add so much noise, distortion and compression that all of these differences are masked. I used to use a ML38 with extensive mods, including about 30 feet of point-to-point pure silver wiring. It thought it was really transparent. Not bad, but not even remotely close to a good TVC.
