Wayne's got a very good point. There's an extra piece to that puzzle that reinforces the value: Outlaw has proven a commitment to maintaining their performance/value product line. That means the 990/7700 combo is still a significant value today, but in a few years you can factor in the ability to ugprade the 990 to a next-generation successor (selling your 990 for a respectable share of the original price, if history is any indication). The 7700 (or 7500 or 7125 or whatever amp you might have) can stick around for many years. True, that's been a selling point of separates for years, but the cost of admission used to be restrictively high.
