Fascinated By GR Research Channel

Lately I've watched a number of the videos on GR Research's youtube channel and been very intrigued. If you aren't familiar with them, they design and sell some speakers, but most of their business is DIY speaker kits, and doing upgrades on customer's speakers. In the videos, they show how they measure the performance characteristics of speakers sent in and then explain the thought process and methodology of choosing improvements. 

If nothing else, anyone wanting to better understand the technical section of reviews (e.g. John Atkinson's in Stereophile), would likely learn something watching.

Another interesting aspect of these videos is the clear untangling of various manufacturers' choices in balancing cost for performance and the sonic impact of various compromises. 

Get your popcorn and check it out. 

I'm also curious to hear of your experiences with any of their kits or products and if your findings match their messaging. I've always understood that better parts quality will improve sonics, but this channel demonstrates exactly how with great clarity...fascinating! Cheers,

Spencer

I tried the GR-Research kit for the Klipsch RP-600m

They certainly sound different.  Better?  That's in the ear of the beholder.  I like them with the mods.

The kit lowers the sensitivity of the speakers quite a bit.  I did the mod on one speaker and left the other stock.  I could not listen to them as a stereo pair with the balance  centered.  Kind of gave me a headache.

Listened in mono with the balance skewed to the modified speaker.  Definitely takes more power to get to the same volume level, I'm guessing it's now an 85-87 dB speaker.

Been listening to them for nearly a year.  No complaints.  I prefer them over stock.

I would try one of his speakers but I'm going with the Criton 1TD-X next.

I've watched a few on recommendation. Mostly rubbish for the ignorant.

Just one comment about parts, sometimes a less expensive part will sound better in a given circuit. Throwing expensive parts at a crossover might get you better sound, it will certainly get you different sound.

When he started putting down the design of the Harbeth is when I decided to unsubscribe. 

I wonder if it was this video regarding Harbeth (starting at the 9:30 mark)?  That was definitely an interesting take on its crossover...; I personally find it useful to get a peek inside a speaker and get an idea of its part qualify and construction quality.

I agree he doesn’t seem to push his products hard at all. It also would appear that if you are the first to send him a particular brand and model to play with, he will do the upgrades for free. This helps everyone in the long run.

All the best Danny.
