GR Research Upgrades


Has anyone here had their speakers upgraded at GR and if so, did you hear any significant sonic improvement afterwards?

I was considering sending in a KEF R 11 for them to take a look at and see what recommendations they may offer.

Just the thought of the shipping a speaker to them sends shivers down my spine as I have had one speaker severely damaged during a cross country trek in the past.   

After their analysis, the speaker is then shipped back with all the new part and you do all the modifications yourself, (to both speakers).

Is it worth the risk?

Yep, you're right, everybody loves Danny!
As far as my speaker not doing anything right, I've only heard the speakers in demonstration rooms but I have pre-ordered a set and thought on the way here, I could have them dropped off at Danny's shop and be evaluated. If there was a bunch of "cheese" I would ask him to do up a kit for me. Who knows, maybe they'll be in great shape and need nothing!
Well you have a plan, AND shipping now, is expensive. Might as well send them there first. Save the money on the double shipping and LESS time spent overall in shipping lanes.. Lower the odds so to speak.. :-)

He always answered EVERY single Email with me..

I can be a bit of a Terrier when it comes to understanding why I'm spending my money.. He understood VERY well..
He has the patience of Jobe!!

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.
