Re: [SlimDevices: Audiophiles] 1900 euros + tax for digital upgrade and power supply for Duet
I've heard this thing. It sounds really amazing. I don't know why. I was comparing the s/pdif output of the Transporter to the Lampizator transport, using an external DAC. I didn't buy one, but if it were free, you can bet I'd happily hook it up. I wish the designer used as touch instead of a duet as the base. Right now it can't pass 24/96 because the server thinks it is a duet receiver. -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=90022 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

I've tried every file that was giving me trouble before and I cannot reproduce the popping noises. I can't say I've ever received service like this from any company, anywhere. To identify an issue and have it addressed so quickly speaks volumes about the way this team was put together. I realize that much has changed since the days of Slim Devices, but I have to say it's been a great 2011. To have both the Transporter resurrected as the Transporter SE (even if it's temporary, it's nice that they are available) and have a code issue addressed so quickly and efficiently is more than I could have hoped for. Thanks very much Andy for finding a resolution.

I've been working with support on ticket 101225-001163 and have provided some files to test with. I've tried to upload them to the site Andy recommended, but have not been successful.

Re: [SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
Turning off scrolling and all screensavers does minimize the noises. Unfortunately, it does not eliminate them entirely. I don't know the firmware code, but I am a programmer by trade. The code may still be computing the values necessary to scroll, even when scrolling on the display is turned off. I also found no effect when turning off the VU meter on the secondary display. Again, the values needed may be getting computed, but not displayed in any way. -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=84133 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
So, I used Foobar2000 to create the flac files with the standard flac executable from Sourceforge and I'm not getting any pops or clicks with the Keith Jarrett track that has been my test track. For a complete test, I used Foobar2000 to create a compression level 8 version of the track. The Transporter did have trouble with this file (clicks and pops returned). Apparently, I'm riding a fine line with this track and the CPU resources of the Transporter. I'm still disappointed, as firmware version 80 worked just fine. I guess I'll just redo all of my high-res tracks with Foobar2000 and hope that gives me the headroom the Transporter needs. What happens when an even more CPU intensive track comes along? -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=84133 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
I was able to reduce (but not eliminate) the popping and crackling by disabling the Music Information Screen and turning scrolling off. It looks like every time the player "thinks", I get a pop with the Keith Jarrett tracks. Something interesting is that if I take the wav file and use sox to create a flac with the same syntax that is in convert.conf (sox -q -t wav $INFILE$ -t flac -c 0 -r 96000 $OUTFILE$), I get a file that is ever so slightly larger at compression level 0 than the standard flac executable. This file does not crackle. If I use the standard flac executable that is part of dbPoweramp at compression level 0, it crackles. I don't know what sox is doing differently to create the file, or why the compression is slightly lower. If I disable flac transcoding and use native PCM in file types on the server, the wav file plays just fine. The combination of FLAC decoding and the new CPU load in the firmware updates is just a bit more than the unit can handle. I have never opened a bug, but I do have a ticket open with the help desk. I will refer them to this post so that they can see what others have written. I never tried firmware 84, as the nightlies were at 85 by the time I started experimenting. -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=84133 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
This is only present on 96k 14bit tracks. The one I see it most is when playing track 2 of Keith Jarrett's "Koln Concert" from HDTrack.com. I recompressed the files at compression level "0" with dbPoweramp after purchasing them. Something odd: When I uncompress the file and play it on the Transporter as a wav, it plays fine. The thing is, I have have not customized the file type playback on the server, so all wav files will automatically be transcoded to FLAC with sox at compression level 0. I even see sox running on the server while I play the file. It should create the same problem, but it doesn't. I do wonder if there is any resampling going on there. I also tried disabling FLAC playback to force all FLAC files to be sent to the Transporter as PCM. I am sure there is no resampling there, yet the songs play fine. I am using the Music Information Screensaver as well as the VU Meter. I might try turning those off. I'll report back... -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=84133 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
I did some more experimentation with Transporter firmware 85 and have identified that the "popping" and "clicking" issue is definitely related to compression and possibly caused by the Transporter running out of computing resources. I noticed that the tracks most impacted by the popping noises were ones that I had to "re-flac" at compression level "0" in the past to have them play correctly. With firmware 80, this was enough. With firmware 81 or 85, I have to convert the files to wav format to play them without artifacts. Something in the new firmware is using resources that were already scarce, pushing the decoder over the top. I suppose I can store all high resolution files in wav format, but I've opened a ticket with the help desk to make sure this is known by the development team. -- Celeritas Transporter -> Classe' CP-47.5 -> Classe' CA-201 -> Martin Logan SL3 Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=84133 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
[SlimDevices: Audiophiles] Popping noises with Transporter firmware 81 and 85
After upgrading to 7.5.2 today I started noticing "static pops" in high-res tracks and while the player changed tracks. I used to hear a similar "pop" when the DAC would go from 44.1/16 to 96/24, but this was now while music was playing. I began to wonder if it was the new firmware version 81. I updated my "transporter.version" file and installed firmware version 85. Same problem. I downgraded the firmware to 80 (still using 7.5.2 server) and the pops went away. Has anyone else experienced this?

Re: [SlimDevices: Audiophiles] Transporters Future?

Re: [SlimDevices: Audiophiles] Very very strange Transporter problem
I have experienced the same issue. If you re-encode the file at the default "5" compression level, the tracks from HDTracks.com will play fine. I run them all through a FLAC->FLAC recompression when I get them and it has fixed all problems I have encountered. I have the same songs that were refrenced in this thread. I had to do the same thing with files I purchased from Blue Coast Records. You don't have to disable native FLAC decoding. If you compress above "5" (6,7,8) with FLAC on 96/24 material, this can happen. -- Celeritas Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=72413 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Transporter or wait for Touch?
Borrow a Transporter from a dealer and try it. I was very impressed and am very happy I purchased one. You might be as well. You can always purchase a duet controller if you want a fancy interface on your remote (or use an iPod Touch). I thought about using a Duet Receiver and an outboard DAC and chose the Transporter. I realize that part of that decision was around the fact that the Receiver cannot pass 96/24, but still, the DAC in the Transporter is excellent and you don't have to worry about running the signal to another box. The analogue outs are excellent (I use the balanced). Unless you really want the interface on the Touch, I recommend the Transporter. -- Celeritas Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=74471 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] 24/94 doesn't work on transporter
Sure enough, dropping the compression level on the FLAC compression fixed my problem. I'm using FLAC at the command line right now with the binary off the FLAC sourceforge site (1.2.1). I dropped it to 0 and the file plays fine. I then ran it again at 5 and that plays fine as well. I'm a little surprised that using best compression was the problem. This is the only song I have that didn't work, but I suppose the CPU is near its limits with 24/96 material, so every little bit helps. I use 8 for all of my 16/44.1 material, but will remember to use 5 for all high def material to be safe. Thanks for the help!

Re: [SlimDevices: Audiophiles] 24/94 doesn't work on transporter
I have a similar problem. I purchased a 24/96 file from Blue Coast Records. They sell their songs as wav files. I can listen to the wav file with no issues on my Transporter. If I put the wav file into a FLAC container (at -8), I get stuttering audio. No rebuffering problem, as the buffer display shows 100%. It's just an odd stutter. I have done a factory reset, but not the xilinx update. I will try that tonight. I will also try a lower compression option. I can't tell if the wav is being downsampled when I listen to it natively. It shouldn't be, but the controller does say "converted to 706 kbps)". Is there a log entry when sox conversion is done? There is no entry in my SqueezeCenter log when I play the file. Is there a way I can disable that feature to be sure? I even ran the file through a transcoder to make sure it's really a 24/96 wav and it only plays uncompressed. Other files I have purchased from the same site at 24/96 play fine in FLAC containers (at -8) and other 24/96 FLAC files I own play fine. Any ideas how I can check to see what is different about this particular file? -- Celeritas Celeritas's Profile: http://forums.slimdevices.com/member.php?userid=18887 View this thread: http://forums.slimdevices.com/showthread.php?t=60763 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
