warm"ness" is subjective. period.
a guy used to dai-ichi blasters, proline eq's & taiwan made pioneer and jbl 6X9s all his life might suddenly find entry level mordaunt carnivals the greatest speaker he's ever heard, while a more advanced user might have a totally different opinion.
i used to only listen to those alien looking components bought from anson and abensons, funny... because I've always had high end car audio. when my fascination for cars came to an end and I started on pdvd in 2006, the first speaker I bought was a floorstanding carnival 6 from mordaunt short... i thought it was the most awesome thing I had ever heard inside the house.
afterwhich, i started paying more attention to the stuff that my relatives had... B&O's, Bose, B&W's, Yamaha's etc etc.. throughout all the speakers I've bought, missions, dynaudio, jmlabs, wharfdale, acoustic energy, miller&kreisel, sonus faber, aurum cantus... i've come to realize, the best speaker isnt always the most expensive one. its the one that your ears fall in love with.
which brings me to an encounter with mr. lim when I was looking at some audio stuff at rockwell, a tangent cdp connected to a primaluna prologue tube amp and a mirage bookshelf speaker (or just correct me if I remembered the brand wrong).
after a couple of mins of listening, I said, I dont like it. it sounds too bright.
He was dumbfounded!!! I could FEEL the shock on his face. As if to tell me... SIRA BA TENGA MO?! But I couldn't help it, It was really what my ears were telling me. And all his years and years of experience couldn't convince me otherwise.... but he wasn't wrong. Hell, he may be right. But in the end, ako naman ang nakikinig e, so my ears must be KING.
Again, warm"ness" is subjective. Price has nothing to do with it.
(PS: just for reference, of all the speakers ive tried and owned, Dynaudio's are truly the most awesome. Whether on a tube amp, AVR or power amp; dvd player, cdp or tube cdp... IT DOES NOT DISAPOINT.... I'll even bet my money to match it versus the B&Ws, Focals and Monitor Audio's of the other members here... but then again, will their ears tell them what my speakers tell me??? probably not.)
