Anyone experience Cala Mighty Sound Denon 103's.


I've dealt with the French outfit Cala Mighty Sound a couple of times and have had great experiences. In fact I've recently ordered a Schick plinth for my Garrard 301 which I'm looking forward to. Does anyone here own or have heard one of their Denon 103/103R rebuilds? Looks like they put a good deal of work into them. Thanks.

FYI, I am planning to send this cartridge off to Ana Mighty Sound this coming weekend. I 've been busy with work and other audio projects (bought a Reel to Reel system). I ordered a new 103R today so that it will be fully run in by the time the 103.3 returns and I can do a real comparison. 
I just got around to sending my cartridge off today.  I am ordering another LP Zupreme head shell so I can compare the new stock 103R I purchased to listen to while the other is being modified.  When the 103.3 returns, I'll compare them both (stock to modified) and report my findings. 
Looking forward to the reports. Big fan of the 103 series and always interested in new "flavors".
