You're right dude - not a good match by any means. When I recommended you the Nagaoka (at the time you were using a Rega), I didn't know you were gonna get a 309...
The Jelco, however, should love the Naga!
The 401 is a lovely deck, but the problem is you've poured more love into your Techy (maxed it out more), so that's having a significant influence on proceedings.
The Garrard has enormous potential, but will need a not inconsiderable amount of dosh spending on it before the quality of its music making will better what you're getting currently from the Techy.
If you want my advice, dude, I'd sell the 309, keep the Garrard (it's too good to sell), put it into a bigger, better plinth (like those from Loricraft) and fit a 12" arm like an SME M2-12R (it's far better than a 309 will ever be):
...pop the Oyaide headshell on it, with a DL103, and you'll be laughin' - now *that* would defo worry the Techy!
Marco.
P.S Have you tried the Oyaide mat and weight on the Garrard?
