With all due respect but when you ask for a "Forgiving, musical speaker"..."but {not} too detached or polite...." you might be asking for a contradiction. Perhaps you might be better off with a very neutral speaker (with good depth) and a high quality equalizer?
Forgiving, musical speaker....
Seeking something similiar to Vandy 1 or original Meadowlark Kestrals...basically a speaker that has a fair amount of soundstage depth but too detached or polite for classic rock...going used...so the m oí re suggestions the better...older PSB?
