when i first got into this weird hobby i was buying separates for below £50 a go off
eBay, used. and i found a few gems at that money. never in a million years did i think i would ever spend £2.5k to £3k per unit on anything. but i have, and up to now, i think on the whole, i've got value for money.
where this stops, i don't know. but as long as the spend gives the desired results, then as long as you are happy with it, its not overpriced.
aspirational products, like £100k speakers will only ever be stuff to read about.
e.g focal utopia speakers, way out of my league, but the focal sopra... well, they are achievable.
second hand or ex dem, but thats getting close to the aspirational but at a more realistic price.
