Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 2.0
Hi Audio Bling I have not tried any of the updates made by Boulder, Audiocom international or Fidelity Audio. So I can't comment on this. But they have given me inspriratin by the very short modification descriptions they have on there web sites. Regarding the external Clock modules. There are many DIY clock modules out there and I have already used a few of them with satisfaction in previous modifications of CD players. At that time I did not make measuments of the jitter / Phase noise. I did only replace the already mounted crystal with a clock module / PSU. Yes it would be interesting to test these clock modules against the modification of U14. But some times you just need to make a desition of what to do. I also think it is fun to see how good the existing circuit can be with these few modifications. It could also be fun to try some of the descrete regulators on the market, just like the 3 stores Boulder , Audiocom Int. and Fidelity Audio.

Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 2.0
Hi Percival Sweetwater / Soundcheck Sorry But I have No Circuit description or diagram over the SBT. In my work as RD HW engineer I have a lot knowlegde regarding RF and Digital circuits and the related components. This knowledge is what i'm been using for re-engineering the SBT. Please be aware of I have only made modifications for the SPDIF output and only for the Coax output, not on the analog section. I have also measured the Ripple of 5V Supply for the SPDIF optical transmitter and USB. For now, I have not spend time to reduce this ripple. I have only measured at the optical transmitter connector and this ripple is pretty big. I bet, that there will be improvements in sound stage if this ripple is reduced. -- Caad Caad's Profile: http://forums.slimdevices.com/member.php?userid=9350 View this thread: http://forums.slimdevices.com/showthread.php?t=84742 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles

If space is not an issue. You're probably right. It doesn't really matter anymore what format you're running. Though I belive that flacs+tags are better supported then wav+tags in general. When it comes to decoding. You pretty much confirm that decoding flacs on the Touch is causing nasty (in audiophile terms) side-effects. That's what I'm saying since quite some time. Streaming your .wav as PCM stream - that's what you do now - is nothing else than decoding the flacs on the server and stream them as PCMs to the Touch. Practically we're ending up with the same result. 2. Decoupling clock Great to see somebody is able to do some serious measurements. It seems than that it is really a rather poor (in audiophile terms) implementation of the clock surrounding electronics causing the trouble. I will try your mod. Would be nice if you could take a picture how you've done your decoupling mods. I just received some NPO caps for decoupling purposes - I'll try it right away as soon as I exactly know where to do it. Cheers Hi Soundcheck Here's attachment of the modifications i have made.

Re: [SlimDevices: Audiophiles] soundcheck's Touch Toolbox 2.0
Hi SoundCheck, Phil and all the Audio tweekers. I have read a lot here on the forum and Sound checks SW mods of the Squeezebox Touch(SBT). I have tested some of there mods will thank Soundcheck for your ambitions and energy. I have though done some other tests that inspired me by reading and testing Sound check SW mods. Soundcheck claims the SBT sounds better if the internal processor works s little as possible! In Toolbox 2 you claims not to decode flac by the SBT. Please see Toolbox 2 -- 1.1.1 Server Based Decoding This inspired me not to use FLAC at all. In the matter of fact. Why do Audiophiles use FLAC or other compressed standards? The only reason is to save space on the Harddisk. As I see it, it must only have been a problem a couple years ago when the hard disks had less memory. Todays hard disks have a lot of memory and I don't see why not using uncompressed standards as WAW instead? I decompressed some FLAC files to WAW and did A to B listening tests. -WAW was tested to sound better than FLAC. I now disabled the Servers file setting for WAW from FLAC (FLAC/SOX) to FLAC ( Disabled). -This made the WAW files to sound even better. The only problem by using WAW types --FLAC (disabled) with this was only when using my iPhone as remote and playing 24bit/96kHz files. This way of using a (WLAN based) remote made the sound totally noisy after a few restarts of the WAW files. NOTE: This problem only occurs when using a WLAN based remote and not the IR remote that is delivered with the SBT. Please also note when using the internal SBT server and a USB storage Hard disk. This way will only play the WAW 96kHz files with FLAC disabled. (I like that! :-) ) You can check this by using the remote control and click the + bottom and check the bit rate. Note: I have NOT listening tested WAW files between using the internal SBT server and the computer based server. Please comment if you have tested this. Regarding the Clock: I have decided to install a clock module in the SBT. But before doing this i decided to test the quality of the SBT internal clock. This was made by using a PN9000 phase noise meter from Aeroflex. The Jitter was measured on the 24.567MHz Clock to 0.6pS (yes yes yes 0.6pS) Measurement Test point was output of the switch U15. When the Jitter level was so low, I then decided not to replace the Clock with a separate clock module. (Because all the clock modules on the market has higher jitter level compared to the SBT's internal clocks) But I did also measured the Supply ripple to the Hex inverter (U14: LVCU04A) that are used for OSC the two crystals. The Supply ripple was measured to approx 100mVpp. I then decoupled the Hex inverter locally direct across the Pin14/Vcc and Pin7/GND. Using a SMD Tantal 100uF and a 100nF SMD cap. This decoupling reduced the ripple to below 10mVpp. A phase noise / Jitter measurement was made and the clock jitter was now below 0.5p - When making a listening test, The sound stage was improved to a new level by making this HW modification. Please note I have ONLY made jitter measurements on the Clock only. NOT on the the SPDIF signal!! Do ONLY use SMD components for decoupling. Do NOT use leaded because 1mm of the lead will introduce around 1nH and this will increasee the ripple between the Pin 7 and Pin 14. Regarding the SPDIF: Please use the same ripple reduce modification that are made for the Hexinverter U14 to the SPDIF output buffer U34. This modification will reduce the supply ripple with approx the same as for U14. Result is that the sound stage will improve even more.. More HW modifications can and has be done, but i believe these two above vill make a good job for a few pennies. Please feel free to comment all the above modifications and tests. But please do not make any conclusions if you only have an opinion and have not tried the modifications. Above modifications will after my opinion bring the SBT to a much higher level. My setup are as follow: Mac with installed Server - SBT (with Teddy pardo PSU this is modified by me)- CIaudio vda-2 (modified by me) -- Homemade balanced Pre and power amp -- Duelund original Speakers. All cables are Duelund.

Re: [SlimDevices: Audiophiles] Problem when Playing WAW on SBT
Hi Phil Thank you for answer this question, and sorry for the late reply.

[SlimDevices: Audiophiles] Problem when Playing WAW on SBT
Hi. I have a problem with playing WAW files usually 96k/24b on SBT. Then the sound coming out of the SBT sounds like a FM tuner that is tuned in between two stations. (Noise only). Well It Usually the first couple of times works OK when I start to play a song. Then the Noise comes every time i start to play a WAW file. It is possible to play Flac and MP3 files. But when I return to play WAW, the Noise returns. I have setup the Squeezebox server to play the waw files following: In filetypes: WAW Flac Deactivated MP3 Deactivated PCM Native There are No problem with noise, only wonderful music in the speakers when: 1) When I play the same 96k/24bWAW files using the buildin SBS in the SBT. (in this case the SBS in the SBT does NOT Convert using sox) 2) setup the Squeezebox server to play WAW Flac Flac/sox MP3 Deactivated PCM Native I have tested this problem and it occurs on Squeezebox server ver: officiel releases 7.5.3, 7.5.4 and two builds(32302 and 32364) of the 7.6.0 It is tested using two different MAC computers. (2.53GHz Mac mini and 2.66GHzMac Book Pro.) both running OSX 10.6.7. Both running via WLan. I have only tested the Spdif Coax output because I'm using an external DAC. The problem is only when playing WAW files. Then why do I play WAW instead of Flac? I have read Soundchecks threads and studied his Toolbox in following link: http://forums.slimdevices.com/showthread.php?t=84742 When reading that Soundcheck could hear different between transcoding and Native playing Flac files. Then I asked my self why in the world playing FLAC when the HDD today has the size enough for WAW files. I also converted some Flac files(HDtrack downloaded) to WAW and did A-B tests between Flac and WAW. and Sorry to say it but every time the WAW file was played the sound was much more realistic, better perspective, depth, micro dynamics etc. This was tested when playing the files from a USB memory stick via the buildin SBS in the SBT Please see 1). I then wanted to make the same test using the same setting of files on the Squeezebox server Please see 2). and now only Noise comes out of the speakers.

[SlimDevices: Audiophiles] Linear PSU for Squeezebox Touch

The Current limiter is temp-regulated, so i have added a big heat sink if Current schould exceed the 1.5A. Also and I'm not connecting a USB HDD or using the internal SBS. Only problem is that the output pwr drops around 400mV when setting the load to 1.5A. This is not a problem because it is possible to adjust the output voltage by a Potmeter. but Will the SBT surwive the 400mV over voltage when the Linear PSU connector connects to the SBT The Squeezebox Touch accepts 5VDC input. Does anybody knows the Max tolerance on this inputvoltage? 5VDC +/- ?V Thanks -- Caad Caad's Profile: http://forums.slimdevices.com/member.php?userid=9350 View this thread: http://forums.slimdevices.com/showthread.php?t=81682 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Linear PSU for Squeezebox Touch
Thank you for your replies. Several types of linear outboard PSU has been recommended in several forums. And also in this Forum.! I have though respect for you guys in here. When you say that there is no different in soundstage when using different outboard PSU. I believe that your experience with the SBT and an other PSU then the supplied already has been tested? What types of PSU has you tested? Thank you for your information regarding supply the SBT with 5.6V ( 600mV Overvoltage) when using a battery. Regarding Ground loops. I also believe in avoiding ground loops with proper system setup. And my experience is that this can be tricky... By the way: regarding avoiding groundloops: do you guys have any good experience using optical cables for the SPDIF(Toslink) connection? Please Check this interesting link for updates regarding the SBT. http://soundcheck-audio.blogspot.com/p/squeezebox-touch-great-base-for-network.html I find this link very interesting. I have not yet tested all the modifications, so I can't comment the author modifications. All these has made me interesting in making this upgrade. I have not yet listen to the System yet, because the PSU is yet not ready for use. One thing I can say (hear ) for sure is that a Net filter in front of the Original 5V adaptor PSU will improve sound stage. This Net filter will filter both incoming noise to the SBT and Outcoming noise from the SBT / original 5V adaptor PSU. Regarding HW modifications: It is correct that there are Switch supplies inside the SBT. And these can properly be improved. I also believe that the Clock circuits can be improved if Low Jitter(Phase Noise) OSC is installed instead of using the installed two crystals that are running on 24.576MHz(for 96KHz samples ) and 22.579MHz(for 44.1KHz Samples). the OSC must of cause have own regulation for each OSC. This will be a future upgrade. Decoupling caps in the right values and in the right places around the Digital supplies could properly also improve the Jitter of the Digital output. The reason for not buying the transport are that I'm driving the Digital output into a outboard DAC. The digital output Jitter of the SBT are lower when compared with a Transporter. Please see Links: Jitter measurement for SBT: http://www.computeraudiophile.com/files/SBTouch_Jitter_SPDIF_0.jpg http://www.computeraudiophile.com/files/SBTouch_Jitter_Toslink.jpg Jitter measurement for Transporter: (see fig 10) http://stereophile.com/mediaservers/207slim/index4.html I have NOT test this my self but I hope the above links shows valid measurements.

Re: [SlimDevices: Audiophiles] SB3 VS the Transporter
Comments on free hand wiring.. Yes.! Free handwiring is basic Not a Good idea in a mixed signal enviorioment like the SB3.

This is not more an antenna than the original PCB design is on the breakout board. Acctually the only difference is the noisygnd path on the main pcb. If we take a look at flying components that are placed direct at the opamps output. An opamps output is very low impedance and this will make it more imune to rf-interference compared with a high impedance. But Yes, an optimum pcb layout is still to prefere.

As you can see this is done by placing the components from the opamps output to the RCA connectors in a flying configuration and cutting the PCB conncetion to the RCA connectors. Please see this on photos. The GND to the RCA connectors was made with hookup wires. This last mod with seperating the signal GND from the PCB GND was really an improvment!!

Hey.. Thanks for your replies.. Here is how to mod the SB3. Replace the PCM1748 DAC with the PCM1748K-grade. This is the only semiconductor that was replaced. I decided NOT to replace the pwr supply with a linear one. (just for fun. It will properly be even better with the Linear version. I have to test this in near future. To attenuate the 5V switch mode Pwr supplys ripple, 2pcs Black gate Caps 220uF/6.3V N are placed On the 5V input of the SB3. C6,C11,C16,C17,C20 Replaced with a 47uF/6.3V HQ Blackgate C7 Replaced with 2pcs 47uF/6.3V HQ Blackgate C10 moved from solderpad to the pins of the DAC C12 replaced with 220uF/6.3V N Blackgate (they have no problem to handle the 8V DC supply to the opamp) furthermore an extra 220uF/6.3V N is placed direct on the supply pins of the opamp. C15 replaced with a 10uF Black gate. C19 is removed (No need of a ceramic cap on the Analog supply of the dac) Following components has replaced and mounted in the air between C21, C23 pads and centerpins of the RCA connectors. The center pins of the RCA connectors has been disconected to the PCB when mounting following six components. C21,C23 replaced with 47uF/6.3V HQ Blackgate, C22,C24 replaced with same value but styroflex versions. R12, R14 (220R) replaced with holco 33R. Last the GND of the RCA connectors has been Cutted. and two wires have been placed direct between the opamps GND and each of the RCA connectors.

[SlimDevices: Audiophiles] Re: SB3: Absolute phase shift
Dear Slim D Support. As an Engineer and audiophil, I do a lot of tests and development of home made DAC's As you properly know a lot of CD's are not recorded or made in absolute phase +. Acctualy a lot of Cd's , Yes even different tracks on the same CD are not recorded with same absolute phase. This is a problem when you are a audiophil. I would like to ask you guys if you can implement absolute shift feature in the SB3. My suggestion is that it should be possible for the user to make the absolute shift function via the remote control while the music is playing. The SB3 used DAC (PCM1748) has this feature in register 22. Datasheet can be downlioaded via this link http://www.ti.com/lit/gpn/pcm1748 I have also made a lot of tests of digital filters. Eg the filter in PCM1748. Also here there is a sound difference if you use the filter function either soft or the sharp rolloff . The SB3 used DAC (PCM1748) has this feature in register 20. Why not implement this feature so the used can decide what sound he /her like best? I think you will be the first company on the market with this feature if you implement it as a user defined solution. Last question. This is just a question and not a request for implentation I can see that 24bit/96kHz not are implemented in the SB3. Only max 44k1Hz(11.2896MHz crystal running) and 48khz(12.288MHz running) are supported. Is it possible to to achieve the 96KHz samples with replacing the 12.288MHz crystal only with a 24.576MHz crystal or will this need modification of the sourcecode? As far as I know this implentation is already in the Transporter? .
