Well, my current set up isn't a typical "best audio deal", but I think that it would qualify based on value for the money spent.
Mains: B&W CDM1-SEs, purchased from a partner for $600 in immaculate shape.
Receiver: Sunfire Ultimate Receiver, retail is $4599, purchased for $3000 (no tax) shipped, then burned out by Comcast during installation (hot plugged). The receiver is still under warranty for another 4 months, but I'm not sure if it will be considered covered since it's improper use. I offer them a deal to pay for shipping ($45) or shipping plus repair ($45 + $265), whichever it ends up. It turns out Comcast figures it's easier to just pay the cost of the item and move on. I end up sending it back. Final cost of Sunfire Ultimate: $45.
Sub: Sunfire TrueSub Signature, retail $2299, paid $1100 (again no tax) shipped.
Surrounds/Center: I'm still working on upgrades, so I'm using Cambridge Sound Works Towers (retail $1599, purchased for $1199), Center Stage ($399, purchased at $299) and The Surround (S) ($399, purchased for $299).
Display: Sony Grand Wega, retailed $8500 that first year, purchased for $4000 at One CALL FOR $4000 SHIPPED,
Some decent deals all around, but I'd have to go with the $45 Sunfire Ultimate Receiver. LOL
