Recommendation on speakers for listening to live music

I am a Dead fan myself and used to have Klipsch Heresy’s, the horns work well for live music. You would need to add a subwoofer or two to round out the low end. 

Budget?

As non-acoustic music is usually heard though the sound system the live music venue uses---which rarely doesn’t employ horns as it’s midrange and tweeter drivers, the advice to listen through horns at home is not without merit. But be for-warned: if you haven’t heard horns in a home setting, you may be in for a shock. They can be very "forward" sounding, and sometimes "brash".

I tried listened through my band’s Altec Voice-Of-The-Theater PA loudspeakers, and found them way too colored for my taste. But then lifelike vocal and instrumental timbre is exceedingly important to me. Art Dudley didn’t seem to mind a little editorializing in his loudspeakers, and loved his Altec’s. To each his own!

I have 2 systems

both low power tubes

one has Ref 3A de Capos

the other Klipsch Quartets (horns)

I like both but the de Capos are much more refined and the Quartets always feel like live music
