Is the MoFI UltraDeck wit the MasterTracker cart the best TT solution @ $2,499?

@chakster
I agree those compliance numbers are very strange! Something seems fishy about it all; not sure I would trust any of those numbers. There is no reason for an MM to be that low in compliance. I’m sure it’s a nice sounding deck, but definitely I’m in the SOTA camp for value-for-money. And you advocate Technics decks which look very very nice, or other Japanese DD, I’d definitely choose that before an UltraDeck too.

I emailed MoFi regarding the tonearm. Here was the response:

The UltraDeck Tonearm Effective Mass is  25.14g. We have mounted many cartridges from Ortofon, Grado, Hana, Audio Technica, Denon, and others that work great with both of our turntables. You want to avoid any cartridges that are specified as high compliance but the majority of today’s cartridges are either medium or low compliance and will work great with your turntable.

 

The compliance of our cartridges at 100Hz is available;

Studio Tracker

 Static compliance : 35 x 10e-6/dyne

 Dynamic compliance : 8 x 10e-6/dyne

Ultra Tracker

  Static compliance : 35 x 10e-6/dyne

  Dynamic compliance : 10 x 10e-6/dyne

Master Tracker

  Static compliance : 40 x 10e-6/dyne

  Dynamic compliance : 10 x 10e-6/dyne

25g effective mass is more believable, but i still have a hard time believing that, just eyeballing this arm with its lean straight arm tube and affixed headshell. Are there lead rods in the thing? Lol. Or are they counting mass with the MasterTracker cartridge mounted?

Their dynamic compliance numbers are also really low, as mentioned before, and very far from the static numbers - which makes it seems likely they’re measuring dynamic at 100Hz like the Japanese, rather than 10Hz like everyone else.

Oh well, at this point I think you just have to take their general advice on cartridge matching.

Thank you everybody. 
I remain as undecided as before...

I'm also an owner of the UltraDeck. Zero complaints, and would recommend it.
