Looks like you saved yourself a lot of money.
Hopefully you have cured the proclivity to do a massive upgrade at lease for a few years.
You might start accruing some HT funds just in case that expensive day arrives.
For example, in the past I used to put $150 per month into a separate bank account for my "Hobby Fund".
That's less than my monthly Wireless phone bill.
$150/month seems a lot less painful than spending $5,000 all at once.
In 4 years, you'll have $7,200 to spend on an entire new Audio/Video system.
In the mean time you can continue with your research, planning, and dreaming. Must have something to look forward to.
