I would say Legacy Whispers. They can be magical, especially with a tubed front-end. Lots of speakers, 95db efficiency, open air design, really nice. Can be had used for your price range if you can find them.
Best speakers for Classical music under 10k used
I currently have an upgraded pair of Thiel 2.3's that I have been happy with but am now ready to upgrade. I plan on listening to the Thiel 7.2 and the Wilson Sophias. I was wondering what others I should seach out? For 'classical' music only - big orchestra to solo instrument
