Meridian DSP8000's
Pioneer/TAD Reference One
I would say some of the bigger PMC three ways. Obviously dependent on room size and budget. I have the PB1is which are fairly low down the range and they render large scale orchestral music extremely well. My dad has the quad esl57 electrostatics which are good but the bass and treble are rolled off and there is a slight low mid boost. The midrange is great and they sound great with orchestral. The PMCs are similar in some ways with regards to the midrange but the whole frequency spectrum is more accurate. Much more scale. I recently went to a classical symphonic concert and was expecting the sound to sweep me away compared to my hifi. I was actually shocked that when I got home and put the hifi on that it sounded extremely similar. In fact I preferred it. I dare say if we could have sat a little closer to the orchestra I would have enjoyed more impact but I was surprised what can be achieved in the home.
i home auditioned a pair of pb1i's and was very impressed with them, had them for a week and was about to buy them when i got a offered a second hand pair of mb2s's which blew them out of the water so must agree that large pmc's definatley would fit the bill
Quad ESL-57's can sound quite excellent with all kinds of music including full symphony orchestra. They always played plenty loud enough for me when sitting a few metres from them actively listening. I'm not one who listens much past 85 db which was well within range for the quads. If you want to go apeshit with volume, get horns.
Provided absolute volume isn't a key parameter, I'd fancy a pair of Magneplanars. They seem to get the energy into a room in a way rather different to a conventional pistonic driver. A bit like the Quads, at a guess, but with better bass and more impact.
Big Maggies would probably do it, with a nice big SS amp pushing them.
