I'm not quite sure where this belongs either, but I don't mind its being here. [JohnR may decide otherwise though.]
I've been haunting DIY Audio, Meniscus Audio, Madisound, Computer Audio, and Parts Express Tech Talk forums for ideas on speakers /subwoofers mostly, but also DACs and preamps.
I've found some interesting items by clicking on the advertisers on 6Moons, Dagogo, etc. Less often, I'll see what is happening on Mandarin Chinese websites. It requires a lot more effort on my part (my Chinese isn't as good as it once was), but I get exposed to stuff that either doesn't exist here or is considered very esoteric in N. America.
Oh, my wife hates this one, but every time we travel, I make a point of checking out audio shops just to see if there are interesting wares. I try to arrange for her to shop while I do this.
I have a pair of two-way speakers, 'Adelphos', designed by Jeff Bagby and sold by Meniscus Audio that are amazing. Now that they have fully broken in, I wouldn't hesitate to compare them to Revelator/Ring Radiator stand mounts. I say this because I just listened to a pair in Vancouver BC last week. That pair was made with a 5.5" Revelator/Vifa Ring Radiator tweeter driven by a Rogue Audio hybrid int. amp (100W/ch) which is reasonably similar to my AVA 400R. If you're looking for 2-way stand mounts for approximately $1000, either the Adelphos or the Kairos will satisfy. The Kairos has a slanted front baffle while the Adelphos have vertical front baffles.
Our audio world keeps changing and shrinking.
