Nagaoka MP-500 cartridge

Yes, it's the SAS-1. Just became available again, now with sapphire instead of boron cantilever. I bought it to fit the Arcam P-77, but it fits the 201 fine. Not sure about the Pearl.

And, yes, I did mean the 150ANV.

Maxson: Thanks for the info. How did you know the SAS-1 would fit the Shelter 201? I have an AT150MLX, which comes standard with the boron cantilever (like many Nagaokas) but the AT150ANV has a sapphire cantilever like the SAS-1. The boron replacement stylus for the AT150MLX runs about $258 but I notice that the Jico SAS-1 with sapphire cantilever is $211. Strikes me as a relatively good deal. 

I picked up a Shelter 201 just to check it out and I'm pretty impressed. I take it that the SAS-1 replacement stylus noticeably elevates its performance?

Thanks in advance.

I didn't know in advance that it would fit the Shelter. I bought it for the P-77. Then I saw online it would fit the Shelter.

I've had the Shelter for quite awhile but hadn't mounted it recently. When I did I was really happy with how propulsive it was, even explosive. Putting the SAS on it made it much more refined and just as dynamic. 

The boron cantilever SAS was around $150, so it used to be even more cost effective.

I have a few Nagaoka's.  They have a signature sound and all of them sound more 'alike' than different from each other.  If you have a Denon 103 MC, you will find that the Nagaoka's are their MM counterparts.  They are laid back, with outstanding bottom end, beautiful midrange and clean clear highs.. Not a 'sparkling' sound, but one you can listen too day in and day out for hours on end.. Smooth and relaxed. 
One of my daily drivers is an MP11 Boron.  Listening to it now.  

Norman, thank you. How much laidback? Goldring 1042 that I run with Nottingham Spacedeck/Spacearm is neither forward nor laidback, I'd say, it follows the recording. No sparkling highs either but very clear too.
