hi michael,
your preamp selection really depends on the whether you will use the quads or go with the atmas. the atmas work best with an atma pre and the quads would probably sound best being fleshed out a hair if they are stock. there are a number a really fine pieces to choose from but getting the bam in front of a tube line output stage will do really wonderful things for your music as you will see (especially an older not battery unit).
the old quad pres were ss so you want to go with a unit that has a tube line output stage, not ss or a passive either.
call me and i'll give you a list to look at.
