Whats a good matching preamp for Threshold S/300?

Cary 2002 SLP 98, CJ's, Juicy Music,

I had one for many years with the Audio Research sp11 preamp and it was a great combo. It drove B&W 801/2 with ease.

I have often heard that Threshold and Audio Research matched well together. It must be an input-output impedance thing. Try researching both of these products starting with the SP11.

David99 If you end up getting the Sp11 ,I still have a NOS set of tubes for it.They have a few hours in them but you can have them if you wish...3 for the line stage and 3 for the phono section

Thanks all,I like the recommendations for Audio Research.
I have considered these as a possiblility myself.
I like the build quality and looks of Audio Research products.I've never heard one though.
I wish I could afford the SP-11 but it's too far out of my reach.
The SP-9 II is more in line with my budget.
Can anyone comment on the sound quality/performance of the SP-9 II ?

Thorman,thank you for the kind offer.
