No money, if no-one purchased from companies short of advertising cash, such companies would never reach the point of solvency (advertising or other) of ML, Krell, Linn, B&W, etc. So, any new Co with little seed capital is doomed to go belly under for lack of sales...
If on the other hand they get a sales boost, it would compromise on quality!
While I don't know about the latter, I disagree about the former: many present-day robust manufacturers started out in a proverbial garage... and *have* cash (advert or otherwise) today.
Granted, not all inherited a precision engineering operation in Scotland -- but surely there's hope!
Cheers!
