stevecham makes a good point. "Warmth" I believe is a subjective term and is dependent on the human ears, speaker pairing, and room acoustics. I can only add my opinion concerning NAD gear since I have experience with the brand.........
The C326BEE is a good choice. While power rating is nothing huge it still has the current to drive many speakers adequately. I believe the 326 is the only slightly older NAD line to retain it's model designation when their newest line came out. It is closest to the NAD 3020 (a vintage classic) than any others in that price range. The NAD amps a couple of steps up in power from the 326 don't sound quite as musical.
I have a trusted dealer and, while auditioning amps, he recommended the 326 although he had higher priced models. The C356BEE, while being more powerful, didn't sound quite as musical as the 326. I settled on the C375BEE which sounded as good as the 326 but with a bit more power. It has the capability to add a phono and/or DAC module but I haven't added either to my system.
So, auditioning used/vintage stuff is difficult unless you have access to a dealer who carries used equipment. Good Luck.
