Yamaha NS-5000 is the detail power speaker. It is also fairly rare so it will perform better on the resale market. They handle 600 watts maximum so rock and roll will sound excellent. The design is handsome and space efficient for WAF. The woofer reveals drum/bass textures better than any I have heard. To get the best out of them you will need at least 400 watts. They used their technology resources to make beryllium obsolete despite those 200,000 NS-1000's with Be tweeters they sold.
Good Speakers for Rock and Roll Under 15K
I have nice speakers for acoustics, jazz, vocals, etc. but are not great for rock and roll. Would welcome any recommendations for speakers that do a great job with classic rock and roll. I will add some components in my system that might influence thinking:
New Audio Frontiers Tube Preamp, New Audio Frontiers 845 Tube Power Amp, Lampizator Atlantic DAC, Innuos Zenith Streamer, Tchernov cables.
