Re: [SlimDevices: Audiophiles] How good is the DAC in the Squeezebox 3?
I'll agree that most off-the-shelf equipment is designed to put the clock in the wrong place, and that modifying it can be difficult. Not necessarily impossible, but certainly non-trivial and possibly not worth the effort. If you're designing equipment to do it that way round in the first place, though, it's perfectly straightforward. -- AndyC_772 AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=35642 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

[SlimDevices: Audiophiles] Will a Meridian 556 enhance the SB3?
I have an opportunity to pick up a Meridian 556 fairly cheep. Do you feel it'd help my system out? I'm breaking in a pair of Omega Grande 6's with Fostex drivers and comparing them to my BW DM602's. Both currently run off of the Jolida 102B. My Zhaolu D2.5 is primarily used as a headphone amp/dac in my office connected to a PowerMac, not as a DAC for the SB3. -- kphinney SB3 Zhaolu D2.5 JoLida 102B Omega Grand 6 AKG K501 kphinney's Profile: http://forums.slimdevices.com/member.php?userid=10409 View this thread: http://forums.slimdevices.com/showthread.php?t=35975 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Their 566 DAC is very old, the data sheet is from 1996. http://www.meridian-audio.com/data/566.pdf If it is cheap enough, it might be worth a flyer. But DACs get better with Moore's law. maybe not doubling every two years, but getting significantly better. While Meridian stuff is well engineered and expensive originaly, I would not expect something that ancient to be much of an improvement. A used Benchmark DAC-1, on the other hand, sounded much better than my SqueezeBox. I used it until I got my Transporter. Both the Meridian and the Benchmark have fairly stable prices these days so you could buy one, listen for a month, and sell it if you are not in love, without losing much money. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Sb4 ?
The current SB3 is pretty mature as a mass-market hardware device. Attractive form factor, nice display, good sound quality, all the basic connections one would normally need. There needs to be more work on the back end to make it Joe 6-pack friendlier, and if they could get the price to $150 that would expand the market a lot. For audiophiles, something between the SB3 and Transporter would be good. $600-$1000 with an excellent DAC and standard-sized case. I really wish they could do a full-width display, too. -- Pale Blue Ego Pale Blue Ego's Profile: http://forums.slimdevices.com/member.php?userid=110 View this thread: http://forums.slimdevices.com/showthread.php?t=35881 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Sb4 ?
I'm betting the SB4 will resemble something I suggested a while back. The wireless card/DAC function of the SB would fit in a pretty small enclosure if it weren't for the display - so why not detach the display entirely and add it to the remote? Make it color, decent resolution, capable of displaying album art or playlist/album list information, and allow it to be docked on the main unit when it's not on the coffee table. If done right (think iPhone) I think that could be a huge hit. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=35881 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] How good is the DAC in the Squeezebox 3?
As some of you know this is exactly what I have implemented in my system. I have a home built DAC, the low jitter clock is in the DAC and feeds the SB3 as well, tapping in where the crystal usually goes. The I2S signals that go to the DAC chip are then tapped and fed to the DAC where they are reclocked by the main clock and sent to the DAC chip. This works extremely well, the jitter on the clock pin of DAC chip is extremely low. I don't have an analyzer that can read jitter that low directly, but by looking at the clock spectrum I estimate it to be somewhere around 8ps. My original version just used a 1.5 foot ribbon cable between the SB3 and the DAC box. I have now replaced that with LVDS signals. The final jitter going to the DAC chips is the same, but the ribbon cable carrying full logic level signals radiated a fair amount and caused significant ground contamination. That pretty much goes away with the LVDS. As described this is fairly simple connection. Unfortunately that restricts you to one frequency. If all you do is listen to 44.1 CD music its fine. But if you listen to internet radio that is based on 48KHz sample rate, you are out of luck. My recent implementation gets around that, I have both a 11.2896 and 12.288 oscillator in the DAC, send both to the SB3. I also send the MCLK from the SB3 to the DAC (this is either 11.2896 or 12.288 depending on the sample rate the SB3 is using). The FPGA in the DAC determines which clock the SB3 is using (very simple circuit, a 8 bit counter clocked by the local 11.2896, and another clocked by the MCLK from the SB3, if the counts are the same, its the 11.2896, if the SB3 one is larger, its 12.288). This circuit muxes the two local oscillators to send to the DAC chips. It works quite well. The extra mux in the clock path should add a slight bit of jitter to the clock line, but I have not been able to either measure or hear that. An intersting side effect is that I can hear a significant improvement in the analog out from the SB3 when being fed the external clock, even with the jitter added by the trip from the clock to the SB3. I was expecting the jitter in the SB3 from the very unoptimized clock feed to be worse than its own clock, that didn't turn out to be true. So yes the architecture DOES work, and works very well. If you want to use a commercial DAC it will take some modification to make this work, exactly what is going to be dependant on the DAC of course. In many cases its not all that difficult if you are willing to give up 48KHz sample rate.
