I'd try a linn majik. My uncle uses it and I'm always impressed by the smooth sound and its sense of pace. Only 30 watts but it drives my uncle's thiel .5 exceptionally well. You also have limitless options for upgrades. Under a thousand used is not difficult to find on this site or on ebay.
Best Integrated amp under 1k
Can anyone suggest a good integrated amp under 1k USD? Requirements: I need five inputs (for five sources - not including phono - don't need a phono pre-amp). Must have clean tight bass, a good midrange, not overly bright treble. Should be smooth with Jazz, but ready to Rock! Help!
