GR Research Upgrades

I haven't purchased anything nor had any GR upgrades, but what he says makes good sense. Although, I'll admit that I'm not quite sold on the tube connectors.
I do like those Rythmik Audio/GR OB servo-controlled subs, seems like a great application of technology and something I'd be more interested in if they weren't so expensive (per pair). Being the value-conscience hobbyist that I am - instead of spending (think it was going to be $5k plus build and finish), I built a stereo pair of Linkwitz Labs Phoenix OB subs (alt version with Tymphany/Peerless drivers) for $700. Super happy with them. I have had online discussions with Danny, and he turned me on to some great DACs a couple years ago - think it was the Holo May Kitsune edition. Danny seems to be a knowledgeable good guy from my experience.

knotscott - agreed.

mwatsme - nice sub, thanks

Thank you!

I've seen his crossover mods for Klipsch, look like he's on right track here, although I use better capacitors than he uses in my extreme modded Klipshcorns. I do think he'll work with customer and use parts they specify.

I’ve had two pair of speakers modified by Danny. Neither were terribly expensive speakers to begin with but they sounded really good, measured pretty well, and were well made (to a price point) and that tends to be the reason many send their speakers to Danny. Not to take crap and make it good, but to take really good and make it better. Many speaker manufacturers just flat out skimp on the parts quality buried inside the speaker. Danny offers a relatively inexpensive way to really increase the parts quality and in some cases completely redesign the crossovers for better performance. In my case after Danny’s mods the resolution increased and maybe a tad smoother as well. Bass performance wasn’t really affected because my cabinets were quite inert to begin with but he offers norez to help with singing cabinets. Danny sneezes out more speaker knowledge than I will ever pretend to know. Great guy too.

Awesome arch2, this just the kind of feedback I was looking for. Much appreciated!
