QUAD: Cheap pre suggestions for the 303

Having read with interest the last couple of threads on the merits (or otherwise) of the old Quad 303's I was inspired to dig out my old one. What I don't have however is a suitable pre, as I used to use it with a CDP with a good level, volume controlled output. So my question to you learned folk is, What would you suggest as a good (cheap) pre to see if the 303 was as nice to listen to as I remember it ?

Would be an interim measure to gauge if I like it or not and to see if it is worth pursuing any further. Will need 2 inputs, which will be fed by an Apollo CDP and a Dino phonostage. What do you recommend or even WHY for sale ? Thanks for your help.
