James - As I mentioned, I'm exhibiting at the Wigwam show on the 19th March.
I will have a 301 mkII in my DIY deck with linear tracking Arm, so if anyone wants to hear the 301 mkII, I'm in the Syndicate 3 Room.
I've given the deck a bit of an overhaul, greased the bearing etc, while I was at it I checked the cartridge alignment and spent a few nights making sure I was in the "sweet spot".
In my set up, with the Pro-Ject Phono Box RS, this cartridge runs quite hot for a low output MC and the level is as loud as my CD source for instance. I'm using a Fountek Ribbon Tweeter capable of 2kHz - 40KHz, but more significantly, has a rising response above 7kHz.
Because of the later, I have found best results with a 1.4g stylus weight (1.4 +/-0.2 recommended) and the tail slightly down on the cartridge, so the VTA is slightly lower than the horizontal position. In conjunction I have found the loading best at around 200ohm, some tracks are ok at 300ohm but something like the first two tracks on Joe Jacksons "Night & Day" album will sound a bit shrill, drop it back to 200ohm and it tames it enough to sound more natural.
It's really filled out the mid range and added weight to the bass with this set up, note, drop the tail too much and the bass will start to sound muddy.
With a dome tweeter and Croft Phono stage, I found 300ohm, 1.2g and nose down worked best, so you really do have to experiment with the settings.
