I have KEF R3 Meta speakers with a KEF KC62 sub in a similar room and orchestral music sounds great. If your budget is higher, the KEF R11 Meta speakers may fit your requirements. The Meta tweeter sounds exactly as you describe that you like. I’m not sure that you’re going to get all that plus a feeling that you’re “live“ in a music hall, though with any speaker.
Speaker choice
I listen to music at my living room second floor which is open space linking to first floor and about 12ft x 15 ft.
My source is a Naim uniti atom network streamer and my amp is a Pass Labs XA30.5. I use to run this set up with a small harbeth p3ESR. But I couldn’t feel the speaker is not enough as the space is too huge for it. Now I have sold my speakers I m looking for a floor standing pair or a bigger XD speaker.
budget : within $5k used unit. I will buy a subwoofer eventually to enhance the bass if needed. Need to save up.
I listen to mostly pop and orchestra music. I enjoy good and sweet Treble , clear , detail and musical vocal with lots of air and tight and solid base. I like my music that gives me the feeling that I am physically at the concert hall.
Which pair of speakers I should consider ?
