Not to say the there's not deals on integrated, just not as many.
I Wonder why?
Price conscious (emphasis on conscious) value buyers tend to think longer term and tend to buy integrated amps. All the advertising, profits, and sales are geared up for separates. Consequently separates buyers tend to be less value and long term oriented. The fact of the top end of the market being people who actually consider a high price a value in and of itself drives separates far more than integrateds. All these things combine so of course whether they are realizing their mistake or chasing the next big thing either way there's gonna be more separates being sold than the market can support, and so there go the prices. Down. Where they should have been in the first place.
