need a preamp for 2channel ATI amp

i am currently using a kenwood-ka-7300 intagrated amp for my preamp hooked up to a ATI at1502 amp with energy exl-26 speakers.iwant to replace the kenwood for a warm sounding preamp.any advice would be most helpfull.
Conrad Johnson pv10a is very warm, can most likely find one used for around 600 bucks new is around 1200. No remote though, but you won't regret it.
