You could also consider a Creek OBH-10. It is basically a volume control, so it will be the same as running your CD player right into the amplifier. Can't get any cleaner than that. It has one input (just enough) and a remote. It lists for only $229. AudioAdvisor.com has a demo unit for sale for $169.
One of the best "value" tube preamps is the Conrad Johnson PV-10.
