Avi- Good point! Both the AT and Sherbourn units I presume will "street" for a very similar price to the Rotel. The Rotel, *is* upgradeable...

As far as *reasonably priced* receivers, I guess that the manufacturers figure that an *upgrade* is the next receiver in the line. Yamaha RX-V1200 to the 1300. Denon AVR-3802 to the 3803...

I also think that in the reasonably priced receiver market, the products are upgraded much more often by the manufacturer (every year to 18 months) than pre/pros (the Sony TA-E9000ES is almost 4 years old!), so the changes between models are more incremental than revolutionary, so maybe there are less reasons to offer upgrades as well. If that makes sense...
