What is the supporting gear and cables in front of these speakers? I had mine paired with Sugden Class A mono blocks, Saturn Audio power conditioner, DAC & phono stage. All WireWorld Cables. Except speaker cables at the time were Madison Audio Lab Extreme 1 cables. They were magnificent speakers, took several hours to get them placed correctly, they were everything I had hoped for, and were going to be my end game speakers. I now have the confidence 30's and those are my end game speakers now.
The 20's had fast articulate deep bass, the tweeters were not bright or fatiguing at all. Do you have access to different speaker cables? What room treatment do you have? Do you have the speakers positioned correctly?
