I use ADS speakers in my main system. I have the L1290 that were completely rebuilt by Richard So (tweeters, midrange, woofers and crossovers) that I drive with a Jolida 60W tube amp. They sound great.
However, I keep thinking, would more modern speakers sound better? What caught my interest are the new KLH Model 5 speakers, since they are also an acoustic suspension design. Would they sound any better?
