RE: [slim] Bit-correct digital out on Squeezebox?
You have unfortunately hit a known "issue" with the squeezebox. It has beeen reported on a number of occasions that some high end DACs will not lock correctly to the squeezebox. I have a friend with the original Audio Synthesis DAX, it will not lock to the SB when playing FLACs, but locks perfectly with mp3s. Another friend recently reported the same problem with the I lastest Cyrus DAC-X. So far I have seen no comment from SlimDevices on this issue.

Date: Fri, 25 Feb 2005 20:28:25 - Hi, I use an audio synthesis dax decade with my squeezebox. I must first point out that I'm extremely happy with the replay however a few weeks ago I invited some friends round to have a listen to the squeezebox and compare it to a couple of dedicated transports. The other transports were from dpa and Arcam both of which were judged (subjectively) to be better than the squeezebox by all present. Not a very scientific test I know but I agreed with the consensus and to my ears it wasn't a small margin. Now in the ultimate scheme of things a squeezebox / dac combo will blow a lot cd players away even some seriously expensive ones however I believe that it's jitter performance - especially with flac's is less than great. I say this because my dac (the aforementioned dax decade) has 2 methods of locking onto the digital signal - one which can lock onto low quality / high jitter signals and one that will lock onto better quality / low jitter signals. This is denoted by the display of lock or xlock in the dac's display. Without fail if I play flacs I only get a lock however if I play mp3's either native or transcoded from flacs I get the higher quality xlock. What's going on, I'm not sure but it seems to me that there is more performance within the squeezebox than is currently accessible. I'm currently looking into the possibility of improving the clock within the squeezebox which may help things. Of course for 200 quid it's a fantastic bit of kit but I don't think it's going to replace a true high end transport just yet. For me however the convenience of having my entire music library on hand far outweigh what at the end of the day is a 30%ish difference in quality.

RE: [slim] Bit-correct digital out on Squeezebox?
Yes, but it is yet undecided if changing gain from 0x8 to 0x7 will produce bit-correct output with correct phase. See this head-fi thread: http://www4.head-fi.org/forums/showthread.php?t=106249 Unfortunately I don't currently have audio HW capable of recording digital signals with sufficient quality to figure this out myself. If it is verified that the Squeezebox can give bit-correct output with phase both inverted and non-inverted, adding a phase-invert control would be of interest to the audiophile community...

RE: [slim] Bit-correct digital out on Squeezebox?
The audio hardware on Squeezebox sees either mp3 or uncompressed PCM. I assume that whether the server software does a decoding of FLAC instead of just pass-through of stored wav file should not influence the amount of jitter at the Squeezebox digital output.

RE: [slim] Bit-correct digital out on Squeezebox?
Hi, I understand it, but were other factors the same, such as digital cables, volume levels, etc.? The reason why I ask is because I have more favorable result from the same comparison. I compared SB with my Burmester 001 CD player as transport. I did not really sense the difference. Yes, it is highly possible that I do not have a golden pair of ears, I admit. There is a guy in France who is starting to offer mod for SB so that (1) SB is clock syncable with external clock generator, (2) digital output upgrade, and (3) usage of external power supply. Mine is now being moded by him and I am waiting for it to complete. My DAC is already clock syncable and the improvement is substantial to say the least (combination of SB and modded $300 DAC board inside TacT RCS with external clock is better than Burmester 001, at least in some genre). So, when the SB becomes clock syncable with the same clock generator, I expect the improvement to be enormous. To some people, it may not worth investing the multiple of what SB costs, but not for me because I see a great potential in SB as a transport.

Various sources (who I'm too lazy to look up) have claimed that it is or I wouldnt have bought one. However, if you want to test it more easily than the method you suggest, you should find a 44.1K dts sample and send it to a home theater receiver. You can find such a sample by searching for "bit-perfect test" on head-fi.org. If it plays normally, the output is bit-perfect. ___ Discuss mailing list Discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
