I have the MMF7 and used a 99.00 Cambridge audio MM phono stage with good success, Dynavector p75, But not as good as a Musical surroundings Adjustable model the new one I think it is the Phonomina? It was good, very transparant, BUT I now use a Mcintosh Preamp with built in phono which always associated with good raw MM phono stages built in and it is Far better, Why I don't know but I guess the Cartridge is gonna make the choice on what Phono amps they like best in the end... The main difference and problem with the Musical surroundings, Dynavector p75 was they have no Subsonic Filter in the Circuit and My woofers were always working double time with this and in the end as much as people say this causes no problem I disagree, my bass Is far more controled and powerfull with the Mcintosh phono, I believe it is because of the Implemented Subsonic filter in the circuit, because with all the other Phono amps I listed which are very popular and good cost they make your woofers bounce in and out of the cabinet like crazy... With my current Phono amp they don't Move and push excellent bass. To really get a hold on what subsonic is I might be better letting someone else explain it, but I think you should definatly look for units with this filter on it, I think the Quicksilver Tube phono has this and that is suppose to be a killer phono stage and a favorite for about 700.00. Also the new Cambridge audio MM/MC phono for 199.00 has the Subsonic filter on it, it is double the price of the MM stage for 99.00 that I mentioned but should be an excellent one considering the cheaper version with no filter sounds good to me for the money.
Subsonic is basically Low freq. (like 20hz and below or something) surface noise created from the vinyl just from the contact of the stylus spinning on the surface, basically subsonic surface noise, kinda like rubbing your hand on a microphone but you can't hear it.
