If you use the original mat, you don't need them

I found that the sound is less zingy with the rings, sounds calmer. I used the original mat.

Hi Steve,
I think a lot of it was down to the Ortofon cartridge Will used, too, at Owston. Having now obtained one myself I know just how bloody good it is!
You were right, the cartridge is the probably the leveller between Will's 401 and my KAB 1210, especially with the Jelco arm fitted now. It would be very interesting to hear the two side by side again

The SL15 is very nice, like a junior SPU. They turn up surprisingly often and at sensible prices too.

Hi Guy,
Thanks for that. I was told it was similar to the SPU. Do you know the history of both cartridges and what the differences are? I'd be really interested to know!

Not really, I've had both, they both use Alnico magnets and, if I recall correctly, had aluminium cantilevers and elliptical diamonds. Not a bad recipe.
Some stuff here.

I think the SL15 was cheaper than the SPU. The one I had didn't quite sound as big or fine or flowing as the SPU but it was very good and cost me nothing so I wasn't complaining. I'm not sure what the exact technical differences were. I didn't dismantle it to look. I suppose it might be worth asking Ortofon.
You could also ask why they don't make such nice cartridges now! (of course they do still make the SPU)

I thought it had Alnico magnets - I recognise the sound
Basically, it pisses all over the 103s, although of a similar character, but before I go into any more detail do you have any idea what the best SUT would be to use with it?
The A23 is not bad (although designed to match the 103) but I could use more gain and perhaps a touch more sparkle, which also suggests loading and impedance aren't yet optimised.
Any advice would be appreciated.
Marco.

They are low output, not quite Io silly but lower than most. A high ratio tranny would suit.
Something like this on its 1:72 setting would be pretty good I'd have thought.
