I don't know if this helps but I got to hear a 336 and McIntosh 501 monoblocks in the same system (McIntosh C200, Oracle cdp, and B&W N801) and found the 501s to be definately better (i.e. more my taste). The 336 sounded a little dark which made timbral color inaccurate IMO. The 501s were more open and had much better timbre and their extra soundstage depth gave the music a beautiful 3D sound quality. Good luck!
