If they had sold millions, then they would not be in this position
IMHO as a 50 year hi-end audio junkie: this is just the tip of the iceberg, especially for uber expensive kit. Renting an apartment (or buying) in many popular cites is so out of reach for the 99% that even IF they were predisposed to hi-end kit, they cannot afford it: an 700 sft efficiency near downtown Ft Lauderdale is $1700-$3000/mo! And then cars are absurdly priced as is car insurance, etc, etc
Combine those issues with significantly better kit (compared to days of old) at <1/10 the price of the uber expensive kit and... well... RIP
