What is a good, compact sized integrated amp??

I have limited space in my kitchen cabinet for an amp to drive a couple nice ceiling speakers and a pair of outdoor speakers by my patio. I had a old Marantz 1030 but was not satisfied with the sound. Any recommendations of a warm, full sounding yet compact integrated amp that is not going to cost me a fortune. I am open to vintage gear. 12 inches or less of depth is a must. Thanks in advance for any input!!!
