MoFi "Mobile Fidelity" Master Phono.

@superhonestben I had essentially the same experience. I let it burn in for 100 hours using the Granite Audio inverted RIAA CD, as always, before I listened critically. Then I returned it. Like you say, nothing especially bad, just nothing much to recommend it beyond its flexibility. In a stable including an Allnic H3000, VAC preamp internal MC/MC, Modwright PH9.0, the Mofi came in fourth in my system. Too bad because I was hoping for more.I did like current mode more than voltage.

I played it enough and did try diferent set ups, I also bought it 'open box" so it had been played......and probably returned. I listen for the music and gear that makes me respond is what I am interested in. I have Graham Slee ARC, Icon Audio ps3mk2 and even the little cheapie MOFI studio phono and for the buck, its pretty good, just got a Whest two.2 discreet and for the short listening that I have done am quite impressed.

I am not sold on the break-in thing except for tube gear, I have never had a piece of audio gear that went from so so to really great after xyz hours. But others may have had different experiences, I just go by what I hear.

Could be a synergy issue?

Possible but doubtful as I have 6 systems set up and 5 tables with different carts

kind of threw the whole shebang at it, just didnt work for me sonically.
