Fascinated By GR Research Channel

I did not want to say but since @blkwrxwgn says he has an arrogant way about saying things which to me make me question his intentions.

he runs a small operation compared to most speaker manufacturers, his cost basis are entirely different, and it is so easy to cherry pick and criticize everything. Can most speakers and every sound system sound and manufactured better absolutely.

how does he even measure? And to be frank if he is so good do you think he and his kits would not get the attention from the media or big audio distributors?

 

I agree with the OP. Very interesting videos. Even though some of the experts in this forum may disagree with some of the details of his statements, they generally fit my experience, and I especially like the way they are presented, as he points out the capacitors, resistors and inductors he is describing. Very informative for a non-engineer like me. He is not pushing his own repair kit hard. My experience is like he is describing - using some money on component upgrade from a local tech (or diy) is often very well worth it.

 

I have personal experience with a one-off crossover rebuild  that Danny

performed last summer on my circa 1988 Tannoy FSM speakers.

The speakers sounded pretty good before I brought them to him.

He measured the existing frequency responses, cabinet resonances and crossover components. They performed poorly on the tests. He started over from scratch.

 

Once the new parts burned in -400 hours- the sound was much better. He also

sold me some no-rez for the insides and suggested adding bracing inside

in a couple spots. 

 

Was this worth the $200 he charged? Heck yes. 

I also had the opportunity to hear his open baffle system 

with his amazing Dodd gear. The $4k his smaller Open baffle kit sells 

is a steal. I don't think there is an $8k speaker that comes close.

Let's hope he is in business to make money otherwise

his doors would close. I bought one of his power cables

just to support his business. For the $300 I spent I have

no complaints.

He is one of the more Legit people in the industry.

I love his exposees on brands people think are "High Quality".

He shows the crap they use inside. Other Reviewers need to

learn some of his skills.

He is the Real Deal.

 

 

 

 

 

Love the channel, but Danny sounds more and more like he's on a mission to correct all the speakers designers of this world, including the very best.

And don't get him started on cables....

Yes, Danny is sharing his decades of experience, R&D, products, simply amazing.  We are very fortunate to have people like this in our industry helping us to leverage and improve on our existing investments. When it works well, he makes money $ at it!  And, saving $ YOU money too if you can upgrade your speakers. 

Positive Feedback on GR/Danny:

A close friend who does not post here is a very happy customer, recently. I was involved in the self-help project some.  After getting the woofer surrounds and voice coils re-done in the mid woofers, he sent in one of his Vienna Acoustics speakers (recently); its on the recent videos where Danny was "confused, perplexed" by the measured speaker as-is while comparing two VA speaker units from two different customers.  Danny was transparent. It was not a trap set by us, we just did not say much, wanted to see what would happen.

 What Danny did not know is the speaker my friend sent in was recently upgraded, caps, and more.  It was a cheap uplift i/we did to the stock crossover, and better than the stock crossovers, but not the best yet. I could not get my buddy to buy even better parts. It was an experiment with mildly more expensive parts over stock.  Not the max, went from $10 caps to $20 caps at best on try-1.   Buddy was happy with the midway lift from cheap parts to mid-fi parts for a minute. That lasted for a few months then it made him think more, "..what about even better parts and even better design - can these speakers sound even better ???".  Time to step it up, again, he paid the $ to box and ship one heavy speaker to Danny.   

My buddy wanted MORE, wanted hi-fi grade parts and redesign, so he sent it to Danny at GR Research.  Danny ended up measuring and redesigning the whole approach and transformed the stock crossover from a 2.5 way design to a true 3-way design; thus using one woofer for lower bass and the other woofer for mid bass range, the tweeter frequency changed some too. Frequency response looks good, some of the odd peaks and crazy dips were smoothed out a LOT.  Danny provides all the parts in the kit, wiring too if needed. Buddy had to assemble the crossover, soldering it together.  This is something to be aware of and ask about.

Results:

"Sounds much better, more transparent", "more musical" to my friend.  His "wife noticed a difference too".  He uses the revised VA Grand speakers with a Black Ice Audio F22 tube amp and says they "not only sound better but have more output for whatever reason".  This surprised me.  There you go.  Buddy saved about $6-7k on other speakers he was looking at before. Not now, he's done! No need, the upgrade worked in a positive way.  

re: Danny / GR Research - 

Yes, Danny is trying to sell kits. That's what he's in business to do and does a pretty good job at it.   

Note:  Your results may vary and low cost speakers with cheap low grade woofers and tweeters may not benefit as much.  First hand feedback helps I hope. There ya go.
