Is the Ortofon Kontrapunkt A compatible with MMF-7

Artemus, you may also want to consider the Benz Glider. I heard it (the medium output model) on a friends MMF 7 and it was a significant improvement on my MMF 7/Eroica combination.
I went as far as to buy one but never used it, deciding instead to upgrade to a TNT Mk. 5 table and a ZYX Airy 1000 cartridge.

The MMF 7 was my table back into vinyl. I found it terrific! I had to spend significantly more (underline on "significantly") to "really" hear a difference. I wasn't displeased with the MMF 7, but you will hear a big difference in all the attributes that comprise sound reproduction with a more-expensive table and cartridge. However, in no way would I have the cojones to describe the MMF 7 as "crap".

Hammer, don't be insulted by that bullshit! It's like a bird taking a shit on your car, just wash it off.

In my very, VERY humble opinion, MMF7s are not crap and sound fine--don't let snobbery make you feel bad about your equipment.

Up until recently, my main TT was an '84 AR Turntable with a Linn Basik tonearm that I bought for $35 and nursed back to health. There was finish chipped away at the corners, scratches, missing rubber feet, it needed a setup job and the severed AC plug replaced, and the lid was melted on one side. I put a Shure M97Xe and later an Aurum Beta on that Linn and anyone who made fun of my little ragamuffin turntable's appearance had thier foot squarley in their mouth once the stylus dropped.

IMO, the main problem with the MMF7 isn't with sonics but with value. You pay a good sum of money, enjoy it for a while...and what happens? You get the itch...then find that they're not as upgrade friendly as some others. IMO there isn't anything at all wrong with putting a cart on that's worth half of the 'table itself--see for yourself how many people put $4K carts on $2-3K turntables--but I simply think that in your particular case, selling the MMF7 and combining that $$ with the $600 you have to put in on a new turntable, arm, and inexpensive cart will get you a more worthwhile and aurally pleasing upgrade all around.

So choose a turntable and arm that are easy to upgrade and mod when you get the itch again, and I think that would be a versatile and pleasing rig for you. I will wholeheartedly recommend the VPI HW-19 Jr. with AudioQuest or Rega arm, Michell Technodec with Rega arm, et. al., and then seal the deal with an inexpensive overacheiver cartridge from Dynavector, Clearaudio, Grado, etc. The VPIs in particular are very easy to upgrade, and the upgrades are quite affordable, too. If you found yourself with $600 to spend once again, that would probably get you a spring suspension and massive platter on the VPI, which will most definitely make a solid sonic difference.

Best of luck, whatever you decide-

First I want to say that I would never call anyones equipment junk or crap.
With that said, I had the MMF7 for about 10 months. It was great in the beginning. Then it grew old for me. I didn't like the cartridge and looked at my options. Here is the option I chose. I sold the MMF7 for $750. I bought a Vpi HW19jr w/audioquest pt6 tonearm for $775. I bought a Grado Reference Sonata cartridge for $416 inc. shipping.
So, for less than $450 which I would have spent minimum on a new cartridge. I got a TT that I feel is at least twice if not three times better than the MMF7.

Hammergjh, sonically there are plenty of things wrong with MMF, yes I realize its only a $1000, but $1000 dollars is still $1000 dollars. We're getting off the subject here, my initial comment was that spending the money on a fine cartridge like the Kontrapunkt isn't money spent wisely in this scenario. Imo Artemus is better off spending the money somewhere else in his system where he can have more benefit from his investment. What I don't understand is why people are huffing and puffing, its just my point of view.
