GR Research Upgrades

The Youtube videos of Danny’s work, always seem logical and make sense to me. He takes measurements, listens, plans the mods, then remeasures and compares the results. His mods typically just try to fix what’s not right, and enhance the "cheese" components with premium parts. I have zero personal experience with GRs speakers and mods, but I do read plenty of positives about Danny and GR around the web. You could certainly do worse.

Is there something your speaker isn't doing right? OR You just want to see if he can improve it? The question I always ask is there something missing, or sound WRONG?

BUT I haven't changed the type of driver I use for over 30 years NOW.
Small Planars and Ribbons..

I use his double 12" OB servos. Wonderful Subs.. 4-6 drivers..

Danny's a self educated businessman with a GREAT track record and great customer satisfaction and support.. He's a credit to THIS sport for sure.. Easy taking, Easy listening, kind of guy.. Always willing to help..

His cabinet guy is top notch too, just a real professional, easy going bunch of guys, with a TON of business all the time.. They stay busy.

He has a great (non paid) support group too, they love their Danny.. :-)

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.
