I'm not clear on the question , but if the OP is asking if same brand same sonic signature is a way to obtain audio nirvana , the answer is likely no for most of us . If a preamp has a warm sonic signature than the last thing we need is a same brand power amp that is also on the warm side . Two warms don't make a right .
I have owned matching electronic's from Levinson , Audio Research and Ayre , all great stuff but all imparted there own house sound on the music . A variation with one major component can make it very difficult to hear that all to distinctive sonic signature . And it's never a crap shoot unless you purchase equipment without hearing it at length in your system .
