A Canadian penny is about 2.3 grams, so that was the added mass. He says it went a long way to improve the bass solidity.
Hey BigE, fancy meeting you here! That's the 301 with the penny BTW. Typo, looks like...
As it happens I have the Mission 774 arm as well and needed the penny to balance the cartridge or the c/w would fall off the back. Turns out glueing the penny resulted in a slight improvement in bass definition and dynamics. It seems firmly coupling the mass to cartridge is better than simply adding mass to the system.
Satan, thanks for posting your impressions. I've tried the ACE, Glider and Wood (all pre 'S') on the Mission and find the Glider to be the best match overall. Also a few Denons (the 103, 103r w/ wood body, and the above 301) and find they are better suited to jazz or small ensemble. The Benz's have an uncanny ability to untangle complex passages while the Denons are better at assembling instruments into cohesive images. IMO, both brands work very well with the Mission, especially when damping is applied at the trough.
Judging by the photos it appears you have a few mods applied to the arm. I'm particularly interested in the head block mod. Is this another one of J7's creations?
