15k USD Speakers for Classical and Pop Extended Listening, Near setup, Low volume

out of those three that you have listed the monitor audio gold 300 G5 will probably be the best, The MPD Tweeter is so natural and three-dimensional sounding I have the platinum 200g2 which are even better than the gold 300g5 and they're absolutely phenomenal sounding also getting the Townshend podiums and putting them underneath your speakers will improve the sound as if you had upgraded the electronics to much more expensive gear, they isolate vibration down to three Hertz and get rid of pretty well all room problems as well.

I think the monitor audio platinum is better they're much more three-dimensional airy and spacious and the sound stage is more enveloping it makes you feel as if you're right in the middle of the performance and there's no dome tweeter that will beat that MPD. but remember it's still an individual thing everybody's hearing is different.

first of all whoever said that the gold 300 G5 would overwhelm the room doesn't know what they're talking about that room is more than big enough to accommodate them I had them in a room 8 and 1/2 by 23 and they didn't overwhelm the room but I bought the platinum 200 G2 instead cuz they were better but if you really want to improve your system get the Townshend podiums they isolate vibration down to three Hertz and they'll get rid of almost all room problems The improvement is as if you bought much more expensive electronics Best upgrade you could do.
