Budget System matching, need integr amp

Hello, Looking to replace a Yamaha Receiver with a warm budget integrated amp. I want something that isn't treble happy or harsh. Current components that I like are speakers KEF Q15s, cdp Cal Audio Icon MKII, and wires DH Labs. SS Integrated amps I've looked at are NAD C340, Cambridge Audio A3i, and AMC 2100 with matching pre. All under 400. Thanks for any comments
