If you want a little warmth go with the B&K. But if you want neutrality and your planning to add your own warmth go with the 545 MK2 Adcom. Sweet equates to colored but that can sound good too! Too much warmth seems to kill the clarity and detail in the music IMHO.
Adcom 545 vs. B&K st-140
Looking for a bargain amp to drive 4 ohm speakers and mate with tube pre....any thoughts?
