Hi Richard, I do not believe that Naim and Linn dealerships were the only source.
I have not been interested in audio for as long as you, perhaps only 15 years.
The first five of those years were in the hay-day of LINN and NAIM franchises.
I was (as we all were once) a consumer learning about hifi, from the ground up. It wasn't even really a hobby back then.
At my young age, I visited the hifi shops of the north east of England. They were a Naim stockist - but also sold (from memory) Tannoy, Ruark, Audio Innovations, Epos and many other makes.
I bought my first ever hifi system there - all ex demo. It was a mixture of non-flat earth products (apart from theEpos ES11). The epos Es11's didn't work in my room so I replaced them with some Tannoy sixes. At no time was I under any pressure to buy Linn or Naim based systems.
On a rare trip to London - again at LINN's and NAIM's forefront years - I went into two London stores. They both had racks of Naim boxes. I had a great demo with some Linn Keilighs and non-flat earth amplification driving them, and a gyrodec as the source. I bought the gyrodec.
What I'm saying is that in my early years I was visiting LINN and NAIM dealerships, and under no ''foot tapping pressure'' to buy Linn or Naim products... not ever.
In fact, the first time I heard about these sales techniques was on PFM about 5 or so years ago.
I think the reality of consumer experience in my case (I can't speak for others, I'm only a single person) - was different to your experience as a non-flat earth manufacturer.
Incidentally, I was in an 'Audio T' only yesterday. It was as much full of brands like Electrocompaniet as it was Naim. A right old mix. If there were any products missed out, it would be valve amplification.
Valves are still something rarely seen in flat earth shops.
In the last 10 years of course, I've fallen head over heels for valve amps and sensitive speakers. It will always be ''my thing'' now I think. I've been sensitive to it, and despite the apparent ''antithesis'' of the high sensitivity/valve approach to the flat-earth stores, they have never criticised this type of equipment to me.
Generally I've found dealers very good.
A few are truly exceptional, as I've put in another thread.
It would be a sad day if I didn't have ''noteworthy audio'' or ''definitive audio'' to pop into - or no doubt ''walrus'' if I lived in London.
I do think that perhaps these specialist stores may need to change the way they operate to survive, but I hope the great people and wonderful customer service I've experienced continues.
