Hello, here's an update about my MMF 5: I bought Herbie's mat and was happy to find out that it does make a HUGE difference. I definitely recommend it to other MMF 5 owners (if there are still some around).
Also, I built one of those 'ikea lack rack' that you can read about here on Audiogon. I have to say that I completely changed opinion about my turntable. The sound is warm, the soundstage has become wider, the bass sounds smooth, and I can finally do justice to my vinyls (not sure this sentence works in english :)
Finally, I 'pulled the trigger' (this seems quite a popular expression in the audiophile world) on an Aurum Beta S MK II (I found a good deal, so I did not pay its retail price). I still don't have it installed, hope to do it tomorrow and will let you know how it works.
