I like my Ayre AX-5 Twenty integrated amp very much. The sound is different in that the sound is MORE natural and less ’exaggerated’ than my previous amps. This is very hard to put into words. The sound is there with no artificial extra stuff around it. The music is normal meaning it makes music, never adding color or stripping the musical recordings of their textures, feelings, and dynamics. The music from the AX-5 Twenty amp is relaxed and smooth without sounding dark or laid-back. The Ayre Acoustics AX-5 Twenty amp is excellent.
BTW, there is an Ayre AX-5 Twenty amp listed for sale on Audiogon. Another less expensive alternative is the Ayre EX-8 2.0 integrated amp. I hope this helps.
