I own a Grotrian (not a 275 or 277) and the reason I bought it is for the round-mellow tone. If you want a bright Steinway tone buy a Steinway. If you take a mellow piano and try to make it bright you'll get a tinny, metallic tone. To take a bright piano and make it mellow is criminal. I've never used any juice on my Grotrian. We sand the hammers every once in a while, needle as necessary and even iron to improve volume if necessary.
