Been messing about with this Musical Fidelity tube buffer, and while the verdict's still out on whether it's gonna be life-changing (definitely hear the effects on some things, but not others), what I have noticed is that the cables are more of a factor. I said in another post that the bass slackened when using the buffered RR2150 with my turntable, but then, when I used the Audience interconnects I had laying around while my CD player is being repaired (I was using some leftover Outlaw PCAs), the bass tightened up instantly. It surprised me, because earlier I'd said that the Audience interconnects hadn't overwhelmed me when I first introduced them into my system months ago. I keep wondering if that can be attributed to break-in…
