Warm and accurate bookshelves that can handle volume


Hi and thanks for your help. I have been collecting and trying vintage speakers and ended up with B &.W 803 matrix series II, and also Celestion ls700 Se. The latter  are bookshelves and I use them with an NHT SW2 subwoofer. I like them both but prefer the 700s because they more accurately bring out the timbre of orchestral instruments and can be less fatiguing. Troubke is I have a pretty big room and I can’t play full orchestra at realistic volumes on the Celestions without distorting the sound. Are there bookshelves that will be warm, musical and accurate like the Celestions, but can handle volume?  Rest of the system is Qutest DAC, RA LS25 II pre, Adcom GSA555 II speakers. Thanks for feedback on which speakers to try. My reading etc suggests Harbeth Spendor Sonus Faber. Locally have tried kef and paradigm, but can’t get to much else. Will travel to try your recommendations. Seems that satellite and sub will be more flexible and cost effective than tower.

Most of the recommendations here are nice speakers but don’t play very loud compared to the ones that do.

I guess the only way to get loud is to go to floor standing. However, the speakers are pulled so far forward our listening area resembles a small room. I think having a lot of space behind the speakers is good, but does not greatly affect how one calculates room size. I have been doing web searches, and found it is really hard to audition a lot of these speakers. I might travel to a large east coast city in the US but even then only a few will be available. I wonder if the whole model for speaker sales will change. Maybe direct sales like PS Audio, or truck delivery for audition, like magnepan. 

@laddy ‘s 2nd posting seems like a winner to me.

 I recently heard the new MoFi speaker Source Point 10 at Michael Klein’s STEREO Stereo in Pittsburg where they were positively addictive being driven by an ARC I/50 integrated. A modern interpretation of the Original Large Advent on steroids 👍

The Dynaudios I linked to earlier play loud. I have the passive version and the maximum SPL per pair at 1 metre spec is 127dB. This is over twice as loud max SPL as Klipsch Heresys. Not too many floor-standing speakers will even play that loud. They are discontinued and hard to find now but the active version’s SPL at 1 meter spec is 124dB per pair and they still make them. I think if you want any louder than that you would probably need JBL Cinema series.

Might as well give the NHT Classic 3s a listen and yeah, JBL L Classics and perhaps HDI series.

I would tend to agree with the gent about high quality amplification.
