Hi there,
I have a different opinion on the budget mix for your entertainment system, and I beleive the advice i had from my assistant at the shop last month made sence...
He said the once you are an audiophile you will eventually upgrade, whether its in a year or 5 years, but one thing that does not change are the speakers, they dont devalue in price nor gain, but a new speaker currently at around £500 will be £500 in 5 years time to buy new. Speakers can last you a life time, your AV receiver can be upgraded to get better sound out of your speakers.
So with this analogy, i would actually spend as much on speakers as you can, with an ok amp that will run the speakers you want within your current budget.
My mix was 24% Amp the rest speakers/stands/cables
Can't be happier with my set-up and I know i can improve easily in the future by upgrading my AV amp when i can afford it again...
I hope this helps.
Ben.
