If I won a cool 50 Mill, I'd buy a shop load.
In fact, I'd open a shop that could cater for every level of Audiophile.
From Mr Budget to Mr Fat Pockets.
& then there's Mr "Don't Know Anything" to Mr "Knows everything and then some" & don't forget Mr "Thinks he knows but ain't gotta clue."
The shop would have at least 10 demo rooms with remote control Walls, Yes Walls, to get room sizes right.
& have the facility to have numerous components set up for comparison in demo easily.
If I say I stock something it WILL be in stock, won't sell my demo equipment "oh sorry I've just sold the demo" - NO!
My Staff would be trained to give an honest OPINION, but at the same time still recommend a demo.
No more lazy replies "Oh you gotta listen to it" & then not be accommodating during the demo.
Have home demo service too.
But because I'm so filthy rich I would be very competitive on price, probably gain some enemies as under selling everyone. Eventually putting others out of business and eventually be the only chain in the UK.
Once all set up and running smoothly, customers happy, reputation built.
I'd start my round trip of the World for the rest of my life.
Opening stores in the worlds major cities.
Spreading the Love of Music all over the World.
Taking over the world, it will be mine, mine I tell you MMIIINNNEEEE, HA HA HA HA HA !
