@james633 thank you for the heads up on Voltis.
@deep_333 thanks and I do enjoy / have enjoyed my JBL horns (still love my 4035Ps). The goal of this thread was for me to find the best higher-end options that give me the transients/speed of my KLH Model 3s in a better overall offering. Thanks to this great community, I think I've found the 3-4 options that are going to offer that. I'm not looking at it like finding the perfect speaker, more like a watch enthusiast that has a dress watch, diving watch, etc.
I'm down to the ATC SCM40s, Borresen X2s, Spendor D7.2s, and Marten Oscar Trios. The Martens are out of my range but there's a dealer nearby so I'm going to have a listen. I'm still looking for a local Spendor dealer.
@jayctoy congrats on your X1s! Love the look of them.
