Mass produced electronics are extraordinarily cheap. Back when I followed this stuff, there was a firm that produced a 'price per transistor' graph each year. As the chip densities got higher and higher, the line tended toward zero. For all intents and purposes, transistors are now free. £25 will get you a Raspberry Pi with well over 250 million transistors. Thats 0.0000001p per transistor.
Electronics made in volume benefit from economies of scale. A Sonos Play 1 has a streamer, digital signal processor, multiple DACS, multiple amplifiers and multiple speakers for £170 - and Sonos aren't known for their budget pricing.
What is expensive are low volume, niche products. Sell 1,000,000 of something and the development costs are (relatively) negligable. Sell 1000 and those months of expensive development time have to spread out over a much smaller group.
My own view is that niche players will shrink and close or be forced to consolidate - that is certainly seems to be what is happening in the industry. 'High end' will get more expensive, and the hobby as we know it will eventually wither away (from my ageing vantage point, it is already on its last legs)
