I haven't personally tried it, but there is a much cheaper alternative to Onzow Zerodust that appears to be very similar in design. I have seen it recommended by some other users who have used it with their very high end analog setups and they enthusiastically recommend it. It is Extreme Phono's Solid-State Stylus Cleaner.
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.
