Music Server Setup: Airport Express or Extreme?

I’m expanding my audio system to include other rooms in my apartment.

I’d appreciate some advice as to what the Apple Airport Base Station, Extreme or Express (or both together), are the best way to integrate this. I’ve been researching and considering this for a couple years, but it is time to harden my plans and ask specific questions. One area of confusion is with various Apple Airport Base Station models: I’ve read many conflicting reports regarding reliability/functionality benefits between the Express and the Extreme, so I’m a little confused.
I am on a tight budget now. I also want the Airport to meet my general computer networking functions as well as my audio needs.

Here’s the lay of the land:

I live in a multiple story pre-WWII residential apartment building in NYC (I mention this in case building construction effects wireless communications: my walls are plaster/lathe vs. sheetrock; ceilings are plaster and wire lathe; the wiring in the building is from an era gone by, so no contemporary in-wall network cabling, in fact most room only have 2 electrical outlets). With my laptop, I am able to connect with other wireless networks in the building, depending on location. My Internet connection is via DSL. There is a cable installed in my apartment but I do not subscribe.

I want to play music potentially into two other Satellite Rooms in addition to my main listening room: one of those Satellite Rooms shares a common wall with my listening room (perhaps I can just run speaker wire through this wall to power a 2nd pair of efficient speakers?). Another room is about 30 feet away from my listening room.

My main listening room:
Includes my analogue music rig and my desktop computer system.

Analogue Hardware:
I have a vintage Yamaha Integrated Amp, Meridian 508.20 CD player, Polk Lsi9 speakers, Music Hall MMF-7 Turntable, Kimber Kables.
Integrated Amp has 2 pairs of speaker outputs (one pair are unused).

Computer Hardware:
My main computer is an Apple G5 desktop (Dual 2.3 GHz PowerPC w/4.5 GB memory). NO airport card is installed in the computer.

My laptop is an Apple G4 iBook (1.33 GHz PowerPC G4, 768 MB memory, w/60GB internal hard drive). The laptop has an Airport Extreme internal card installed.

I have a dedicated external 500GB HD to store my iTunes music library (which is backed up to a second dedicated external 500GB HD). My digital music files are mostly Apple Lossless (with duplicates in AAC and MP3 files for downloading to my iPod).

My music server as it has been configured for the past 2 years or is an afterthought. It plays only in my main listening room and consists of the External HD (used to hold my music library) that is connected to my Apple G5 desktop computer with just an RCA splitter cable going from the G5’s audio-out to an input on my integrated amp. The Apple G5 runs iTunes. No aftermarket DAC, no remote controls. I control iTunes from the G5 desktop directly with a wired keyboard/mouse.

I want to do 3 things and in separate stages:
Stage 1) I want to pipe music into one other room, Satellite Room #1 (my bedroom). Satellite Room #1 shares a common wall with the main listening room and if need be I could run speaker wires through the wall to power a second pair of efficient speakers. ‘Background’ quality audio will be sufficient for now: I will upgrade the audio quality later as finances allow. I will only ever need to listen to music in ONE room at any given time.
Stage 2) add ability to pipe music into Satellite Room #2 (the living room). ‘Background’ quality audio will be sufficient for now.
Stage 3) Upgrade the DAC.

Remote Control Considerations:
I want to be able to control the music server remotely from any of the Satellite Rooms. For example, I would like the iBook laptop with its internal Airport Extreme card to wirelessly control iTunes (running on my G5) from other Satellite Room locations. What sort of Airport Base Station do I need to purchase: Extreme or Express? Also, does the G5 need its own INTERNAL Airport Card installed in ADDITION to the Airport Base Station?

Eventually, I would like to introduce a pair of speakers into Satellite Room #2 and have the same sort of remote control over the music server with the portable iBook as I have in Satellite Room #1. I expect for the Satellite Room #2, I will need to purchase a second amp in addition to speakers…but what other hardware would I need to get music into the third room? Or how best to realize this on a budget?

I may purchase an iPhone in the near future. I understand that iPhones (or even generic remote control devices) can remotely control the iTunes music server. If so, this would free up the iBook laptop in the event I need a second computer to run the system in one of the Satellite Rooms.

DAC Upgrade:
I’ve read on here much over the past couple years about DACs. Presently, I am using the internal Apple DAC built into the G5 desktop computer. I have read extensively about its limitations and after I get Satellite Room #1 operative, I will experiment with a budget DAC upgrade: maybe a Gary Nixon unit or a Benchmark USB. If an updated DAC sounds pleasing, I’ll sell the CDP and convert my system sources to only a digital music server and vinyl.

***I also want to be able to have the iBook and the G5 wirelessly networked together for general (non-audio) computing and file sharing as well, bear that in mind when recommending an Apple Airport model.

Thanks a bunch for any input or suggestions.

jax2- let me correct some of your statements. 1) you don't need a squeezebox or transporter to get remote control capabilities from the mac. actually you are wasting your $$$ if you get the squeezebox and you could do better by getting different equipment for the same $$$ as the transporter. 2) you don't want to use the monster toslink to rca cable since you will not get the quality of the music that you want. 3) you don't need to use only the toslink connection to the dac.

I'm a bit confused by some of your post. I think you may be misunderstanding my responses. Since you said you are "correcting" me, I'd like to respond: 1.)I made it clear my response was quick, brief and off the top of my head. Basic advice. I don't think I said that a Squeezebox or TP were the ONLY solutions. If anything I said actually could be interpreted that way, it was not my intention to suggest that 2.) I also suggested that there were alternatives to the mini-toslink that Apple provides in their kit (Monster). 3.) This is news to me, so I'd like to learn something here - If you don't use the optical connection from the AE, what other way can you feed the digital stream to an external DAC? As far as I know the only way to stream digital with an AE is via Toslink.

As far as your recommendation for a setup - It looks like a fine way to go and I use something similar in my office system (though I go wired via USB there). Again, since the poster stated he already has a G5 tower he intends to use I did not suggest other computers, and I'd reiterate my warning that the antenna used for wireless for that computer is utterly worthless in my experience (which is why I use an Airport Base Station). The reason I suggested what I did is that I use a Modwright Transporter and the sound from that via wireless or via a wired feed from a transport is better than any digital source I've heard before and surpasses anything I've owned. I believe the DAC in the stock TP is the same one use in some of the very expensive Esoteric players. There are surely many other solutions, some cheaper, some more expensive. Mine is probably not what most consider a "budget" solution. Pick your poison. There are many ways to make it work. Depending on what standards/expectations you have, you may or may not be disappointed in any given approach. In my limited experience using the AE modules via a toslink connection to external DAC's I've consistently been disappointed with the sound. That's not to say that it is not possible that someone else might get better results, or may be happy with the results I was getting. Different strokes and all that.

jax2- the only reason i said what i said is because your initial reply indicated that the poster "needed" to do certain things. IMO, there are much better alternatives to what you stated. let me clarify:

to get wireless, there are many options: wireless card in a tower, wireless built in the new macs, airport extreme or any other wireless router, or even a WAP (wireless access point). i use the wap myself. on craigslist or ebay, you can pick them up for around $10. the wap ties into your network (if you don't have 1, you can create 1 using a small 5 port 10/100/1000 hub). you can get these for the cheap, i can even sell you 1 for $10.

as for the squeezebox or transporter, the screen interface is terrible. i have a friend who sells them. the squeezebox doesn't do anything more than the AE but costs $200 more. the transporter is much better than the squeezebox but for the $$$, you can do better. (also, i don't think this unit uses the same dac as in the esorteric units).

i agree with you when using a connection from the AE/squeezebox to the preamp is terrible. and i mentioned in my thread above the option of using a coax or aes cable into an external dac is using a jitter device between a computer and the dac. the optical cable decouples the computer or AE device and the jitter device allows you to use the better cable connections to a dac. also, until they come out with a dac that has comparable quality using a usb connection compared to coax, i would stay away from usb. the new audio research dac7 might be the 1st.

as for remote control of the music, using the iphone or ipod touch blows away using a squeezebox or transporter. you get a full graphical user interface, album art, page of info on all songs/albums/artists with easy scrolling. all for free when using these devices and itunes on a mac.

also, when hooking up a second pair of speakers in a remote room from 1 receiver using an old yamaha, how are you going to control the source, output levels, speaker switching? depending on how old it is, you probably can't. if it has a multi-source and multi-zone capabilities, then it would work. also, when hooking up multiple speakers to 1 receiver that the amp compensates for the impedance that is presented to the receiver. the impedance could drop in half and that could be a bad thing.

I believe I've already responded by explaining my initial post. My experience with the AE and Squeezebox have been far less than stellar, and certainly would not lead me to wanting to use either in any kind of critical listening. For a system you listen to while doing other things they'd be just fine, IMHO, YMMV.

I completely agree, that the SlimDevices remote interface is not very good, especially in comparison to iTunes.

As far as other wireless solutions; the reason I recommend and use an Airport Base Station is the setup interface is easy and intuitive. It does not require multiple calls to someone in a call center in India with a script. The reason I did not recommend using an alternative internal wireless card for the poster's G5 tower is because the issues around signal transmission have something to do with the all-aluminum body of that computer as I understand it. There are some aftermarket companies making antennas for it, and hopefully Mac has addressed the issue by now. I have a g5 2.7 dual-processor model and a working AirPort card and their rare stock antenna. That setup is utterly worthless and will not transmit a signal 20 feet. I don't know if a different internal card would make any difference, and again, you'd be losing Apple's intuitive and simple interface in setup (the same interface you've praised for their iTunes remote abilities).

The Slimdevices Transporter uses a AKM AK4396 multi-bit delta-sigma DAC. AKM DACs are used in the Gryphon Mikado and the Esoteric D-05.

Again, AFAIK the only source of digital streaming from an AE is optical (toslink). The other connections do not stream digital signals. That is unless the design has changed substantially from the two units I own. Have you used a coax cable into a DAC with an AE?

the AE hookup is not different than what you get with the transporter. all the AE does is to accept a signal wired or wireless from a central computer. that is exactly what the transporter does. so if you think that the AE device is inferior to the transporter in that function, you need to explain why because they both accept "bits" from the network.

like i said above, the output straight from an AE device into a preamp sounds like crap. also, going from an AE device into an external dac sounds better (no different than the transporter device if the dacs are equal). again, there is no difference on what the 2 setups accomplish, it all matters what type of equipment you are using.

i agree with you on the transporter sounds better than an AE device going straight to a preamp. i don't agree with you on that the transporter is the end all setup for critical listening. i also disagree with you on that you can't use an AE device for critical listening.

you also missed what i said in my thread regarding wireless setups and the AE toslink.

get a good WAP device to send wireless signals throughout your home. if you think the card on a g5 mac is crap, great, use a wap device. i got a motorola wap on craigslist for $10 that all my computers, iphone, and ipod touch communicate thru, 3 story house, and in my backyard.

as for the AE/toslink to a dac, you missed my mention of the jitter device. you go "toslink" from the AE to the jitter device, then use "coax" or "aes" or "glass" to your external dac depending on what inputs and outputs you have on the jitter and dac devices. also, the toslink cable decouples the AE or computer from indicing any noise from these devices to the jitter/dac.

also, looking at the esoteric dacs, they use either burr brown or analog devices dacs in there standalone dacs. i really don't look at internal dacs since external dacs are much better.

No, I do not necessarily think the AE is inferior in its wireless transmission of bits. My comments regarding the AE are regarding its function in sending a digital stream directly to a DAC. I've tried it with four - a Benchmark, Wavelength a Muse 2+ and a CAL Alpha (the Muse and Wavelength required some kind of adapter as I recall - but it did not address jitter). It is in that regard I found it's performance lackluster. Soundstage was very limited and dynamics were inferior to the same DAC fed by a CD transport via coaxial cable. My results were consistently poor. I have NOT used the AE with a jitter reduction device in between, as you suggested. You are correct, I missed that detail in your post. Sounds like a good idea. I cannot explain why the performance was inferior, I can just try to convey what I heard. To clarify, I use a Modwright (modified) Transporter. I do not have experience with as stock Transporter. I can assure you that, though it may have the same capabilities as an AE, it does not sound like one...at least to my ears. You made some inference that I was making claims to the effect of it being be-all-end-all front end. I made no such claims. I simply said it's the best I've had and experienced. I'm sure there are many others that do a fine job and even excel. I'm just contributing my own personal experiences and, as with anyone else's, it's worth exactly what you paid for it. Take it with a grain of salt as you would any advice. Try this stuff out as you see fit in your own system, your own room, your own music and with your own ears and find out what works for you.

I didn't make any comment at all about the DAC in the G5. I have no opinion since I've never tried it. My intuition is to get the signal OUT of the noisy electromagnetic environment of the computer box ASAP doing no conversions at all inside that environment.

The Esoteric D-05 that uses an AKM AK4397 DAC is a standalone DAC. The Gryphon I mentioned is a player. Alex Perchev also uses AKM DAC's in his APL players.

My comments about the WAP devices and the G5 are strictly aimed at the G5 towers that the poster said he had. They are constructed entirely of aluminum. There are issues around transmission because of this construction. I've found it best to use an external wireless device, and the Airport is excellent, and easy to setup. It will also transmit throughout a house and outside. Internal cards in my g5 will not transmit 20 feet. This is a known issue. I suggest before you try another type of device you do some research on that issue. As I said, there used to be a few companies making external antennas that mount on the back of the G5. I don't know how effective they are. The one Apple produced is useless in my experience and I believe they stopped selling it. Perhaps some other internal card actually does a better job, but I'd suggest you do some research. If you find something that works well please post it here as I'd also like to know. I'd prefer to have an internal device rather than another box on my desk. In that regard I'd agree with that advice.
