Obscure brands worth considering

There are some companies and their products that are both very well established and financially stable, yet still relatively obscure; Music Reference and Eminent Technology come to mind. Their products aren't reviewed much (models aren't "improved" every other year ;-), and they don't have that many dealers.

A few decades ago I worked in high-end audio, and we did carry some more obscure speaker lines.
What I learned back then is that not all speaker manufacturers build their own drivers, they oftentimes spec out their needs and have them built by other companies, and would order a bulk number of raw drivers, essentially predicting how many they would need for manufacturing and post sale service.
We had a few manufacturers who never seemed to have spares available, especially for our customers who tended to blow tweeters.
Something to think about, if considering a more obscure product.

I buy from well established companies that will stay in business for a while and provide great support.

That has worked for me in every respect except with amplifiers.  Clayton Audio is a USA-based company but really a one-man operation that handles requests but no longer seems to be in full scale production these days.

On the positive side, Wilson Shen is a great guy to work with and a very talented designer.  After selling to go with well-regarded Class D amps, I ended up going back to Clayton amps and commissioning Wilson to rebuild/upgrade the amps I was able to find and purchase.  The guy who purchased my original Claytons remains very happy with them.  Before finding another pair of Claytons, I tried a number of well-reviewed amplifiers but none that sounded so much like real music to me.

Do yourself a BIG favor and seek out JM Reynaud loudspeakers; unfortunately only 6 dealers in the US.

Sometimes some of the finest things in life are the most difficult to find.  Ye shall be richly rewarded.

Clayton amps are in a very high esteem in some circles. Unfortunately, I have never heard them.
Six dealers is not too bad, Nottingham turntables have just one, I think.
