Amp & Pre Advice for Hales Transcendence 8

I finally bought a set of Hales Transcendence 8 speakers. Looking for amp & preamp (w/ remote) recommendations to take full advantage of the Hales. I've read and read, like the older Krell, Pass & Levinson higher power amps (considering T8 inefficiency and bass extension) but I need help. I Have a Hafler 500 or TFM-25 to live with, so am happy to take the time to hunt for the right pieces. Especially interested in others who have T5 or T8s who have tried different amps and preamps. CD or SACD suggestion that would integrate well would be great too. Amp/pre budget is < $5k used. Thanks! (Repost of original post in wrong category.)
