GR Research is over on Audio Circle. He is one of many audio Industries that have a site on AC. I spend a lot more time on AC than Agon, WHY? They is the friendly knowledgeable posters. His articles are well documented with pictures and he answers the why do it this way. Unfortunately, for me, he does not do planar speakers. I will eventually consult Richie for a better xover in my 1.7i Maggie's. There are many nice knowledgeable folks on Agon, but, I get very tired of wading through the politics to get to the gems.
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,
