So, the OP wants a neutral integrated and let the warm speakers be the tone control. Great start.
I like the sound of the Burson PI-160 but lets face it, its not that popular despite its stellar sound (IMHO). I was told that the Hegel line of amps have the very same sound quality as the Burson (neutral and full, at the same time) and look more attractive, to boot. Most reviews have equated the sound as like water: its just there with nothing added. And unlike the Burson, it has a remote, more inputs and a built in DAC. I only went with the Burson because it was $500 cheaper than the Hegel.
If the OP can find a demo, he might be happy.
