Push pull 300B amplifiers

Thanks everyone for your responses. My current system includes Granite Audio 860.1 (KT88 monos), Consonance 2.2 CDP and Equation 25 speakers. Although tubed, it is very fast, detailed and transparent- perhaps too much so for my tastes. The higher power 300B amps caught my eye as adding a little richness to the midrange, while still keeping much of the positive aspects of the speakers and cdp. It sounds as though a well executed push pull 300B may cost a bit more than than the models I am currently considering. Have a Modwright platinum Sony on the way for my other system (Plinius 9200, Harbeth S HL5), perhaps a similar change of source might be a better option.
