You won't get what you are looking for with the Naim. I had the 5i and was very disappointed with it. Its definately not going to be warm. You won't be mistaking it for a tube amp.
The best way to describe the sound is that its not clean. When I say that, I don't mean defective or broken; its just something you have to hear for yourself. I don't know if I can explain it.
I haven't heard the Peachtree so I can't comment on it. Its supposed to be very good, though. Another integrated that you will probably like very much is a Creek 5350. I had them side by side and for me, at least, there was no comparison at all. I couldn't come up with 1 thing the Naim did as well, or better than the Creek.
