Turntable upgrade, tweaks, or stay put?


I have a music hall mmf-7, stock with goldring eroica and project speed box. Rest of system: Wilson audio Sophias, Musical fidelity KW 500, Musical fidelity Trivista DAC, and Musical fidelity CD player. I really enjoy the mmf7 and have no real complaints. However, I know it is the weakest link in my system. I wonder how much better it could be. Do you think I would have to spend $5-6000 or more on a new tt to get significantly better sound? Any recommendations? Or would some tweaks be smarter? Or just save my money and buy more records? Thanks in advance. As I said, I like my mmf7, but wonder if I am missing out by not having something of similar quality to the rest of my system.

Agree with Stringreen.

Also, if you haven't lubed the main platter bearing and motor bearing, that's a simple tweak. Be sure to use the right lubricants. A center clamp and periphery ring clamp are also reasonably priced tweaks and will help a lot. You can pick up preowned clamps on eBay or A'gon for a fair price. And for goodness sake, don't puncture a finger on the spindle needle.

As far as cartridges are concerned, I've tried the Dynavector 20X2 (HO), Soundsmith VPI Zephyr and the Ortofon 2M Black. Yes they do sound different from each other. In the end I settled on the Lyra Kleos. IMO, I like the Lyra the best. Here again, look for preowned. New MSRP will put your wallet on oxygen. No comment about the Benz. Never owned one.

Btw, I used to own the Lyra Delos. It's a very nice cartridge too, but I ultimately settled on its bigger brother, the Kleos.

Couple of points about the Ortofon 2M Black. I seem to recall that it's a high compliance cartridge -- having a 22 compliance factor. I think the VPI JMW arm does better with medium or low compliance cartridges. I suspect the 2M may have had tracking issues and/or the 2M's output voltage may (??) have been a little "hot" for my phono pre. In any case, I returned it. I just couldn't get it to work well.

Similar comments about the Clearaudio Virtuoso and Maestro. They are high compliance cartridges. I had bass ringing issues that Mike (VPI Service) and I couldn't quite get our arms around.

Last point about output voltage. Be sure that whatever cartridge you settle on, its output voltage meshes with your phono pre. My phono pre's does 58 db of gain and the linestage does 12 db of gain. The bottom line is that the Kleos is the lowest output cartidge (.5 mV) my system can handle, unless I start talking a SUT which I am not inclined to do. Just another artifact.

Just sharing. Let us know how you make out.
Thanks a lot for the great advice. I lubricated the platter bearing with white lithium grease, but I am not sure exactly what to use for the motor. What do you suggest?
Check the VPI web site. You can access the Scout's manual there. It will tell you, or just call Jack or Mike. I seem to recall a teeny tiny drop of 40W motor oil, or something like that. VPI may even sell a little stick of it.
For motor shaft lubrication use a VERY light oil. Sewing machine oil works really well. To apply, see if you can get a hold a hypodermic needle which will allow you target the area of lubrication.
I got the scoutmaster set up with a soundsmith zephyr. Will let it break in for a few days, but it already sounds good. Will keep you all posted. Thanks a lot!
