@colasblue , I have sympathy with much of that.
I too still have olive boxes, as the picture on the left shows.
I too am disappointed by what looks to me like a broad range designed for a wide range of customer (many hardcore audiophiles) requirements shrinking to a few apparently 'lifestyle' products plus a very short list of eye-wateringly expensive purist products - more form but less function? Surely a once great brand and product range is being destroyed before our very eyes? Boosting E at the expense of PE?
I am even disappointed by green lights turning white, though in my case that may be a sign of age creating nostalgia - like missing the strong, distinct, publicly expressed and easily understandable views of people called (say) Julian, Ivor, Roy, Touraj, Billy, Ken, Conrad, Dick, Alastair, Helmut, Spencer & Doris and so on.
I too did quite well out of the financial services business before I retired, specifically investment management.
On the other hand, I saw lots people believe that their insight and additional wisdom would cross sector boundaries and show up the inadequate grip of people who had been in that sector for years. Rightly or wrongly, Twitter could be thought of as an example of how that usually goes, like various Virgin businesses, Sinclair C5s and so on, plus almost every successful business person who ever decided to buy and control a football team.
I have not examined the financials of any of these companies (I don't even know if Naim's net profits and operating margins are rising or falling in 2023), or worked in the industry at all, and learned long ago that I would need to know quite a lot before I could produce a useful opinion to rival those of people who actually do this stuff for a living - the devil is in the detail and all that.
If you don't need any of that to make great judgements, that is a rare skill indeed. My snap judgements, guesses and prejudices are probably in line with those of most people on this site or the green one, but in my case that is probably all they are.
