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 - it's actually Steve - aka Willie
But there is a nice ring to Mr. Wonka :-)

Your setup appears to be quite different from my own in that my computer is wired to the system and all remote function is provided via my tablet that controls playback on the computer, from the NAS drive.

In your proposed configuration it appears the TV can stream, but only the Oppo and the computer can stream from the NAS

However only the computer is capable of downloading music files from the web, which can be stored on the NAS for playback via the Oppo or the computer.

It also appears there is an ability to remotely control the Oppo from an Android device, but I couldn't fing anything about using a computer running OSX or Windows for remote control.

So the only issue I can see relates to how you are going to stream...
- via computer - then you have to connect to the Oppo (as a DAC) via USB or Optical or spdif
- via the Oppo - then you have to use the Oppo's remote to control playback.

I may not be aware of some other Oppo/Computer feature so it might be quite possible without any further hardware.

I would NOT worry about the dropouts in your case - I have three neighbours within 60ft of my house and I have two wireless routers in my house, so it became an issue.

I did come across one review that reported problems with the Seagate NAS, but reported the Synology NAS had worked OK. So you might want to go with the Synology.

Sorry I could be of more assistance.
Tim, I usually find it useful when ordering computer-related things to review the user comments at Newegg.com for the items under consideration, while keeping in mind that negative experiences tend to be disproportionately represented. Here are links to Newegg's listings for the two NAS devices; click on the "reviews" tab a short way down on each page, or on the ratings link just under the title at the top:

Seagate STBN4000100

Synology DS213j

I haven't taken the time to read most of the comments, but the bottom line appears to not be particularly good for the Seagate. Also, although it appears in the photos to have USB connectors, there is no mention of USB connectivity in the description or the list of system requirements, which seems disconcerting given your intended connection configuration. And based on the description at Amazon, it appears that those connectors may be just for connection of external hard drives or other peripherals TO the NAS, not for connection of the NAS to a host (the Oppo in this case). For that matter, based on a quick look I'm not sure that the same concern doesn't apply to the Synology as well.

Also, you may want to consider ordering from Newegg, as they are considered by many (including me) to be THE place to go for computer-related parts and accessories.

I agree with Willie/Steve that if the only wireless competition is 100 or so feet away you are unlikely to have a problem with it, especially if:

(a)The distance between the laptop and your wireless router or access point, and the distance between the Oppo and the wireless router or access point, is not especially great, and/or there are minimal or no walls or other obstructions in between.

(b)If necessary, you change the channel setting on the wireless router or access point to be a few numbers away from the channel used by the neighbor's wireless equipment. You would do that via its setup menus.

(c)If necessary (and I suspect that it won't be) you install a top-quality wireless access point such as the one I linked to earlier, and use it in conjunction with your existing router. In doing so, you would turn off the router's wireless function, assuming it has one, which should be doable via its setup menus.

Finally, keep in mind that a RAID 1 mirror will protect against failure of one of the two hard drives, but it will not protect against the admittedly much less likely possibility that a problem arises which can destroy or corrupt both hard drives at once. Such as the RAID controller circuitry or its programming going berserk, or the power supply going into an overvoltage condition, or some other latent design issue that may be lurking in any of the equipment that is involved. At some point you should consider adding a second means of backup.

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
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
