need help with outdoor system

Thanks guys, and to clarify, I am not expecting to get audiophile quality sound on my outdoor deck, I don't think that would be realistic considering my budget for this, which has not been established yet but is probably under $1000. What I really want is the ability to select music from my iPad. I use Jriver and Jremote downstairs in my listening room, running Jplay off of a laptop into my Vlink and DLIII Dac. Schlepping an iPod dock out there is not what I want to do, we're always getting in the hot tub in the middle of a snow storm. That's kind of the Colorado way to do it. Weather resistant speakers would be better...

Considering the price point, I think wireless speakers are out, i think wired speakers would sound better for the same money. I'm starting to get used to the idea of wired speakers run off of my Denon avr's second zone. There is a penetration next to the avr for the coax cable, we dont have cable, never will. i can run wire through there. This will be a long run, like 50 feet or so.
Now I just need to connect my music library to the Denon. I started out in iTunes, with aif and alc files, which the Denon does not read. They got in bed with Microsoft early on, I think they're doing all formats these days, but not my unit. I need to try it with flac, and I've also started ripping in wav, which I'm sure the Denon sees. The most convenient thing would be to connect my external drive via USB into my Denon, control that with the iPad, and power it with the denon's second zone. I don't think I can use Jremote for this, because I don't want to add my laptop and the Vlink into the chain. Too much stuff to move around. So I need an iPad app...that connects to the Denon... The app has to be able to see apple and PC based music formats, maybe I can get the Denon a software upgrade to enable it to do the same. Sounds like a fantasy, but my wife wants music out there, and she generally gets what she wants.

@ DTC - what is DLNA? My AVR has a network card, but I have read that they are unreliable in this unit, and mine is 3 years old, and I've never used the network connection, so not sure if that is a reliable way to go.
Yup, I can connect my laptop to the AVR right now, using the vlink192, and control everything via Jremote on my ipad. Maybe I'll start out there, and upgrade to Sonos later. It's just kind of a pain to constantly hook/un-hook the vlink from my basement system...
Why do I need a Sonos bridge, can't the Connect just jump onto my wireless network? I have a wireless router. I find the Sonos stuff to be kinda expensive for what it does, I realize I get access to all kinds of internet media with the connect, but $350 to hook into my library seems high...it might not seem so bad after a little more research tho. I tried to buy a Sony media streamer because it was cheaper than the apple TV and had composite video outs, but wound up smashing it to bits in the garage with a 3 pound sledge because it was such a P.O.S. Moral of the story - going cheaper doesn't always get the same result...>sigh<
Speakers first! I was looking at the Def Tech AW6500

Looks like I need to investigate which signal on the Denon can be mapped to zone 2. I was assuming that I could just use my old Vlink (I have two) and my wife's laptop to send digital signals into the Denon's DAC, then get that out to zone 2, but I'll have to look. Did not know you could run Jriver on multiple laptops, that helps.
I could run wire from my basement system out to the tub, but there isn't any way to control volume while using Jplay. Using the AVR, I could use an app on the iPad to control the Denon's volume, and select music with Jremote...but the run from the basement office would be a shorter run. My DAC has two sets of outputs, one balanced, so I'd have to buy those interconnects along with the second amp...and I'm running conduit and wire with the AVR route anyway, so I think I'll go there and use what I have.
