Recommend Affordable Integrated Amps (Solid State or Tube)

Looking for an affordable, good sounding integrated amp costing no more than $3500. It must be able to play CDs and Vinyls as well as digital music from iTunes (some 30,000 songs) stored in AIFF format. Currently have an Accuphase E 307 integrated amp  using Kimber Kable interconnects and speakers cables with jumpers. Current speakers are KEF Q700. Analog is Linn Basic with an Akito tone arm and Rega Exact 2 Cartridge. CD player id a Marantz 5004. I listen mainly to jazz, R&B, Pop, world, etc. at moderate listening volumes. Room size is about 17 x 24 feet with 8 foot ceiling.
Would love to have suggestions.
