I need to find a small form-factor integrated amp for my desktop. I'm currently using a spare Cambridge Audio 550A, and it just takes up too much space. I've kept my eye out for one of the Teac Reference 500 integrateds, however ones in good shape seem to be pretty rare and the price has really went up on them. I also don't want tubes, as this amp will get turned on/off and be run for short duration cycles. I use a NuForce uDacII and Polk Blackstone TL-3 speakers. A sub-woofer output would be a bonus, however not required.
Any suggestions for a small form-factor integrated amp for the desk top? Power output doesn't have to be all that high, however SQ does have to be at an acceptable level. I keep looking at the NuForce amps, however I see mixed reviews on sound quality.
