DIGITAL HIGH-RES AUDIO SYSTEM -HELP PLEASE

I need your expert advice on building a 24 bit/96Khz, 24/192Khz max, computer based home audio system I'd like to integrate into my home audio/ht system. I'm not totally clueless on what I need but I could definitely use some advice and direction as well as helpful tips. I have a fairly good audio system I currently use for ht and music playback. So, I'm not starting from scratch but want to incorporate computer audio and WAV and FLAC file streaming and storage into my system. Video streaming and storage can wait for a future time.

My current system consists of the following:
Plasma HDTV
Full 5.1 surround setup (5 spkrs and 1 subwoofer with in-ceiling surrounds).
Three separate stereo amps that power the main l/r, subwoofer/ center and l/r surrounds.
Directv satellite source (box has HDMI and digital audio output)
Older DVD/CD player as source used for movies and music.
Surround sound processor (older unit with just coax and optical audio inputs/outputs, no HDMI or USB inputs/outputs).
Separate tube preamp with HT Passthru. I'd run computer analog outputs to this for 2-channel listening.

For computer audio I already have some components:

Newer Laptop with 4 USB2.0 ports, dual core processor, 2 GB RAM and 110 GB internal hard-drive that can be solely devoted to a computer audio system(only 35 GB free on HD, however).
Wireless high-speed LAN with smart HDTV already attached and streaming Netflix, Hulu, Pandora and Amazon Prime to the tv and laptop.
JRiver v19.0 media player installed but no downloads yet and only a handful of cds ripped.
Cambridge Audio DacMagic 24 bit/192khz DAC.

My current budget is only about $1,500 and was thinking my next steps should be to:
A. Buy a new or used Oppo BDP-103 or, preferably a BDP-105 to replace my DacMagic and Sony DVD,CD player and get at least into 21st century technology.
B. Buy a NAS next to connect via USB to my laptop when more funds become available.

So, please let me know the following:

1. Am I thinking correctly and on the right path with buying an Oppo followed by a NAS?
2. Is there a method to connect my laptop, and future NAS wirelessly to the Oppo? I'm currently running a 12ft USB cable from my laptop to my DAC. I know cabled is better than wireless but curious how much better.
3. Any suggestions for a good, affordable NAS?
4. Does the Oppo BDP-105 have internal surround sound decoding capability that would allow me to run analog cables to my 3 HT amps directly from its analog outputs and substitute for my Parasound processor?

Thanks in advance for any advice and guidance.
Tim

Hey guys,

I've been researching setting up wireless systems on various internet sites in an attempt to wrap my head around how all this is configured and controlled. Something must have sunk in because I think I may have figured this out with your assistance.
Could you please confirm my proposed thinking outlined below? I'd like to ensure I'm doing this optimally for sq but realize going wireless is riskier than wired. However, there might be a fatal flaw in my plan that I'll detail after I outline my plan below.

My current plan:
-Laptop is currently wireless and Oppo and NAS are wireless capable with N type' dongles attached at USB inputs of both.
-Laptop, running Windows 7, will act as the controller with assistance of JRiver Media Center and DBpoweramp software.
-NAS will be setup as a storage device on Windows 7 and downloads will be directed via JRiver to the NAS.
-Oppo BDP-105 will be setup as the 'Preferred Output Device' (I believe just as a DAC is).
-Files stored on NAS would be initiated for playback via laptop/JRiver.
-For 5.1 music, tv and Bluray movies, volume would be controlled via the Oppo's remote.
-For 2-channel stereo playback, the Oppo's 'dedicated stereo outputs' would be connected (via my highest quality RCA intrconnect cables) to the 'CD' inputs of my VTL preamp. Volume would be controlled through the preamp. I may need to set the Oppo to 'Stereo' output as well.

The only thing I'm concerned would ruin this plan is my router. I have an AT&T high-speed internet network but I don't know if the router is capable of connecting and routing information to individual devices within this environment. So, worst case, I'm hoping an upgraded router exists that would be capable of this. Is there such a thing as a 'network within a network'? I may need professional help with this setup.
Any suggestions are very welcomed.
Thanks,
Tim

What is the make and model number of the router?

Hi Al,

My router from AT&T is a Gateway 2Wire with "SSID" and "Wireless Network Key" numbers listed. On the back are also 4 Ethernet ports. Only 1 port is currently connected and runs to my Directv 'Genie' DVR 6ft away. An HDMI cable connects this Genie to a secondary hdtv.

The router and my Genie box are located in my lower level family room. My main system (TV,HT and components) is located a half level up in the living room of my split level house. There is a small 'client server' box located in a low level rack directly below my wall mounted HDTV. This clent server's HDMI output is connected to my tv and the client's 'Optical digital' output is connected to my Parasound pre/pro via Toslink cable.
As I understand it, the AT&T/Gateway router communicates with the Genie via the ethernet cable and with the living room client server wirelessly. There is a wooden studded dry wall separating my living room from the kitchen and dining room behind it. There is a 4-5 ft opening in this wall that serves as a path to the dining room and another 3 ft. opening from the dining room to the kitchen, which is open to the family room a few steps below. The router is located on a desk at the far end of this 18 ft long family room.

The client server, HDTV and my laptop are all located in the mid-level living room and consistently receive strong wireless signals despite the separating wall. I was planning on putting the Oppo and NAS next to the client server in my equipment rack. However, if it is better functionally, I could locate the NAS in my family room and connect it to the Gateway router via ethernet cable.

Thanks,
Tim

Tim - If your concern that the router will not have enough connection capability -then you should be ok - most routers of this type can handle upwards of 100 wireless links - at least the ones I have worked with - which include Bell and Rogers

I think the newer models can handle 256.

If you want more ethernet ports you can simply add a regular router and daisychain it to the wireless router.

If you are concerned about throughput - don't worry - high speed routers perform at rates much higher than audio requires.

I took my wired devices (computer and NAS) up to gigabit throughput and it made no difference to playback - even the 24/192 files

Hope that answers your question

Tim, I really don't mean to be patronizing here, but I think you may be well served if you do more reading/research into NAS. I continue to wonder why you think you need it. In any event, a plan to connect NAS to the Oppo via USB suggests to me a misunderstanding of NAS. An external harddrive is something one might connect to the Oppo via USB, but if you invest in NAS you definitely want to connect it directly to your router via Ethernet.
