You did not mention a budget so I will suggest both new and used.
I have had very good results with Heressy's and Heresy II's with 80's/early 90's Denon PMA integrated amps(80w/ch to 100w/ch). Not what I would call "warm" but about as neutral as you can get with a very tiny lean toward "warm". These amps are fast and punchy with plenty of detail. Expect to pay in the range of $100.00 to $200.00 on the used market.
For new integrateds, any of the NAD BEE line will do the trick. New: C355BEE, C356BEE, C375BEE Used: C372
Cambridge Audio also has some nice affordable integrateds.
