Re: [SlimDevices: Audiophiles] What's better?
Since you guys brought it up, here is a little primer on USB audio. All modes in the official USB audio spec use isochronous transfer, this means the host is sending out packets to match a particular transfer rate (44.1 48 etc), this bandwidth is reserved on the bus. There is no handshake per packet, the host keeps on shoving them out no matter what. There are three audio modes: synchronous, adaptive and asynchronous. (remember these are ALL isochronous, so you cannot say isochronous or asynchronous, asynchronous IS isochronous!) Synchronous connects a PLL to the actual data stream on the USB bus. This is the simplest connection but is VERY susceptible to jitter on the bus since the PLL is directly tracking the bus. A number of cheap early USB audio devices used this mode, but its pretty rare today. Adaptive mode uses a frequency sysnthesizer of some sort to clock the data out of the chip. The frequency is changed slowly based on how full or empty the fifo is getting. The host is still in ultimate control, but the output clock is not directly slaved to the bus, this can have much lower jitter than synchronous mode. There are MANY different implementations of this mode, some almost entirely analog and some implemented in software on a processor. Some of these are actually pretty darned good. Almost all implementations today use this mode. Asynchronous mode, a completely separate clock is used to clock out the data (you CAN use a super low jitter clock for this). A separate channel is opened over the bus going from the receiver to the host which tells the host to occasionally slightly speed up or slow down the transmission. If the FIFO in the receiver is getting empty it tells the host to speed up etc. Note the asynchronous mode is not really the same as TCP/IP, there is no request or handshake per packet, there is NO error correction, if a bad packet is found, tough. (error detection bits are sent, but the only thing you can do with them is blink a front pannel light, there is no retransmission capability) The TI 1020 and 3200 are the only USB audio chips I'm aware of that even have the capability of asynchronous mode, BUT you have to program the chip to do this. This is not easy, I spent many months trying to do this and finally gave up. I only know of one person that has successfully implemented asynchronous mode on one of these chips. There HAVE been a couple of implementations using non-audio USB enabled microprocessors, but again this takes custom firmware and drivers on the computer. The companies that have done this are not high end companies and have not taken advantage of the asynchronous mode to produce very low jitter implementations. The high end companies can't afford the manpower and time it takes to implement one of these, and the companies that have implemented it are not sharing thier implementation with the rest of the world. I hope that clears the air a little on this subject.

Re: [SlimDevices: Audiophiles] What's better?
Thank you for your detailed help. I had not really considered all that a Squeezebox could do. However, the only things that are important to me at this time -- however that may change -- is the ability to use the files on my Mac Mini with my stereo system AND to be able to access my playlists, etc. Also, of course, it is manditory to be able to quickly and easily grow into a better stand alone DAC system. Both of my mentioned options do both of these things. There is one plus for the SQ and one negative for the SQ as well. The plus is seeing the song display. I think that's pretty big. The negative is not being able to play iTunes purchased music. Now, I've never purchased anything on iTunes because I don't like 128K MP3 files. But someday that could change and iTunes will offer Lossless files. Then, maybe I would purchase some music from iTunes. I'm leeeaning toward the Squeezebox as my starting point.

Slimserver is a server application that runs on your computer and does 2 things, primarily: 1) serve music/data to hardware players like the SB or transporter and software players like softsqueeze or media player (via mp3 stream) 2) Gives you centralized control/browsing/search for all your music and all your players via a web interface.

Re: [SlimDevices: Audiophiles] What's better?
When you get your Mac Mini, be sure to disable (under pref. in iTunes) the sound candy such as eq, soundcheck and enhancer. Under applications-utilities-find midi and see that 44.1kHz is checked. Also, be sure that iTunes and the main Mini volume are set at max, and use you pre-amp/receiver to adjust volume. I have a Mini in my listening room and used iTunes/ALAC for all two channel listening. The mini was connected via a glass toslink to my pre-amp. It sounds very good. After a year or so, I decided I wanted an external DAC, researched a lot, but decided on a Transporter because of the positive feedback concerning its DAC. I have converted all my ALAC files to FLAC, and only use Slimserver. The one feature I really miss from iTunes is the ease of navagating through the georgeos Album art view. With the recent iTunes update, it is now full screen. That said, overall, I prefer Slimserver to iTunes.

325xi;189770 Wrote: Why do you think merely having optical out guarantees quality of that mini sound card feeding that out? Or the Airport Express, for that matter. This serious review of the AEX digital out -- http://www.stereophile.com/budgetcomponents/505apple/ -- sounds upbeat, but sections like the following seem a little disconcerting: One operational glitch that didn't affect my system to any significant extent but did do so for some readers was the fact that, as the AE doesn't have a local clock circuit, when the incoming data is interrupted, as it is when you change songs in iTunes, there is no longer a digital output to feed the DAC, which loses lock as a result. Both the Levinson and the Benchmark DACs that I use deal gracefully with the lost lock ... I therefore missed the fact that with some other DACs, the first seconds of a song might be cut off. AE ... is limited to ... 16-bit data only. ... It is also important to note that the AE functions only at a 44.1kHz sample rate. When you play 32kHz or 48kHz data, iTunes sample-rate-converts the data in real time before sending it to the AE. (The SB handles 44.1 and 48; the Transporter can also handle 96k. Both can handle 24-bit recordings, according to http://forums.slimdevices.com/showthread.php?t=32951) Since Apple doesn't prominently post the sort of technical detail that you can get on Slim's hardware (http://wiki.slimdevices.com/index.cgi?HardwareComparison), I think you should seek out such reviews. I get the feeling that Apple included the digital output because of the prevalence of digital inputs in mid-fi AV receivers -- not for high-end gear. Certainly Apple's marketing this as hi-fi doesn't help their hi-fi credibility: http://www.apple.com/ipodhifi/ ...but the widespread praise of the cheap T-amps makes it clear that you shouldn't rule Apple's hardware out just because their gear is not expensive enough!

[SlimDevices: Audiophiles] What's better?
I'm a newby and haven't purchased a Squeezebox yet, I need some pre-purchase advice from folks that have been there before me. I'm just getting into computer-based audio. I have good audio equipment (Cary CDP, Unison Research Amp, VPI TT, Magneplanar Speakers, etc). I bought a Mac Mini that hasn't arrived yet and I'm doing my research right now. I will probably want to move to a dedicated DAC of some sort in the near future, but I'm trying to decide how to best start getting sound off of the Mini's HD. I'm basically torn between using an Airport Express (AEX) and a Squeezebox (SQ). Both have an analog out that I could begin with, and both have S/PDIF ports that I could grow with. The AEX is $99 and the SQ is $249 on sale right now. I'm not worried about the $150 difference at this point. I like the SQ concept, but with the Mac Mini I get a remote control and iTunes and built in WiFi so I'm pretty set. With the AEX I could be up and running off of iTunes in an hour or less using the AEX's internal DAC. With SQ I could be up and running with the Slimserver and pluged into the integrated right away using the internal SQ DAC as well. Then, when I move to a dedicated DAC in the near future, I could use the TosLink SPDIF from the AEX to connect to the DAC (though I'm not crazy about TosLink or the mini adaptor). Or I could use the more comfortable RCA SPDIF from the SQ in a wider range of separate DACS in the future. So, with all the knowledge that you guys have about these choices, which way would you go? Would you say the SQ is really a good way to go at this time -- or is it more of an even draw with the AEX knowing that I'm using a Mac Mini I appreciate your responses and will carfully consider all advice given.

Thanks Some of the big questions to answer (not being super-familiar with apple products these questions are more squeezebox-biased): 1. How much do you care about the Squeezebox's display? For me, having to turn on a tv or a sit at a computer to control my audio is a deal-breaker. 2. Do you want to easily expand the system and add units for multi-room audio? the SB excels at this, allowing centralized control of all audio, synchronization, and great overall flexibility. 3. Do you need to be able to play Itunes protected content? Only apple products can do that. 4. Do you care about always-on access to pandora and rhapsody via squeezenetwork? 5. The SB and slimserver are amazingly customizable with community plugins available to do virtually anything you can imagine, from checking voicemail, weather, sports, integration into home-control systems like xpl and others, and so much more. Are these things that matter to you? 6. Do you care about anytime access to a central database of music that you can access over the internet via slimserver? 7. Do you want to be able to use unique control devices like a pda, nokia770, any computer, an IR remote, crestron system, or any of the other myriad devices that can interface to control a SS/SB system? All of this hits on one major thing: A big selling point of the squeezebox is the overall architecture. It's not simply about how good it sounds or how pretty the web interface is. It's a unique architecture, providing a centralized repository for music that can be flexibly streamed to different playback devices and simultaneously controlled by different control devices. It's very open, very extensible. This is quite different from the Apple model and I think having a good understanding of this difference will ultimately inform your decision. -- azinck3 azinck3's Profile: http://forums.slimdevices.com/member.php?userid=3967 View this thread: http://forums.slimdevices.com/showthread.php?t=33836 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
