Hi all,
I just bought a Mo-Fi StudioPhono pre-amp. The default settings are too bright and slightly brittle. And messing with the impedance changed things. But, first:
MY SETUP:Audio Technica 140 XP Turntable with a Shure M97XE cart with upgraded LP Gear N97xVL ViVid Line stylus. It's going into the StudioPhono and into the CD input of my Onkyo 8020 receiver. Speaker-wise I have: ELAC Debut 2.0 B6.2s.
From what I understand, 40DB gain and 47K impedance is what I want. Buuut, again, that sounds bright to me. For the heck of it, I kept 40DB gain and changed the impedance to 8500 (8.5K) and...well, to me it sounds much more like how it should sound. Way less bright and "brittle". Less fatiguing to listen to.
I know some will say "if it sounds great, just do that" but I'm trying to figure out why it does. Is it cutting out higher frequencies? If so, is that a good thing? Obviously, I bought a pre amp to open up the sound stage. So if lowering the impedance is the equivalent of me decreasing treble on my EQ I feel like I should skip a pre amp and go straight to the onkyo phono input.
