Bestbuy is integrating Magnolia HiFi into some of its stores, starting with 9 in California.
If you aren't in california, the only real way to spend 4,000 is to buy the Lifestyle 48, they'll make that 4k disappear easily.
If they have a Magnolia by you its simple, Denon 3805, some Def Tech Floor speakers, 7001's I believe (self powered with multiple woofers in it)
Boston or Speaker craft speakers, high quality optical, and component cabling, DVD player, all that cool high end stuff, and for around the same cost or less than the Bose.
Get this, BOSE SUCKS!
Its like buying a KIA for a BMW price.
BOSE IS NOT NOT NOT THE best bang for your buck.

I work for best buy, and whenever someone wants to buy bose, I take them back to magnolia and let them see what they could get if they spent their money on quality products rather than overhyped BS.
