I have no problem with bespoke. I have a lot of bespoke furniture at home. It costs a lot of money and cannot be mass produced.
Most of it was made by

Image 45 in the gallery is Rowan Atkinson's TV (the Latin inscription is rather amusing), quite a few of these images are from Roger Waters' country gaff, including his loo at image 29.
The owner of this business was getting commissions from royalty (he did work for Diana at Kensington Palace) and still ran into business difficulties. He got back on his feet and with proper financial management is still doing well 25 years later.
If he could have made me a beautiful pair of speaker cabinets that could then have sounded as good as Harbeth I would have done that. I discussed it with him. It just was not possible. It was not a matter of cost. So I have ugly speakers that sound incredible, but to me it is the sound that counts. The rest of my hifi is hidden away in a (custom-made) unit, so looks are irrelevant.
On the other hand, I had a custom electric guitar made by a luthier for my son. He makes all sorts - lutes, violins etc., many for professional musicians. He could have hand-made the body and neck, but you cannot beat on quality and price custom parts from Warmoth, near Seattle. I think the body and neck cost about $1,100. Everything else was hand-made. The cost (£2,500) was less than you could hope from Fender Custom or Gibson Custom, and his guitar is without doubt better. It's also beautiful.
For the amount of innovation in British audio over the last 80 years I despair somewhat at its present relative lack of commercial success. I look at all sorts of businesses, big and small, some well managed, some not. Yesterday I was with the ex-CEO of a FTSE 250 company that was on the point of collapse. It occurred to me that smaller manufacturers could operate through a marketing co-operative. Some industries do that in the UK, other examples are Italian wine producers.
