Sure mutts, the requirements for amplifying transparently are well-known(flat frequency response, inaudibly low noise and distortion)to design engineers and are applied to even units quite modest in price. So, as long as a unit meets those specs no "undesireable sonic character" appears regardless of make or price. Unfortunately there're quite a few old audiophiles' tales to the contrary floating around based on perceptions not founded on objective evidence. Carefully controlled blind listening tests show that what is claimed to be heard isn't what really is heard when variables in loudness,etc. aren't a factor.
