<font color='#000000'>OK... up to $1500 on the receiver... You would need a speaker level mixer/switcher to control 1 set of speakers from two sources... Not sure I'd do that, since you would want to apply all available monies towards getting yourself upgraded - but perhaps others would have some additional input for a solution.
As for receivers, I'd recommend: Yamaha RX-V1, RX-V3300, Denon AVR-3803, AVR-4802 (find a deal) or some other brands recommended by our Members...
Are you buying speakers right away then for home theatre or waiting?</font>
