YMMV, but some people feel they add coloration. i recently opened up my lightly-modded Sony SACD player, which i've felt for a while was a little bright and tizzy up top. i forgot i had previously added Panasonic polypropylene film bypasses by the output opamp. the Pana P is a pretty good cap, but i realized this was a no-no and took it out, replacing it with some 10uF Panasonic HFU electrolytics i had in my parts bin (they're predecessors to the FC caps). ah, much better... after some break-in much of the tizziness was gone. i'm now very wary of using film caps for PS bypassing anywhere when high-frequency, low-ESR 'lytics (like Pana FC) are already in place. quick question: does anyone find that the SB lacks a little "oomph" in dynamics or bass with the opamp taken out? i mean on an absolute basis, i.e. compared to a good external DAC, not the stock SB. my experience with bypass mods is they are very transparent, but sometimes the impedance mismatches caused by the removal of buffering can make the sound a little thin or anemic. is the BB DAC chip really ok by itself? -- dorkus dorkus's Profile: http://forums.slimdevices.com/member.php?userid=3373 View this thread: http://forums.slimdevices.com/showthread.php?t=19822 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

True? I think it's a great idea to go with an active setup Jon, but at some point did you plan on moving to speaker/sub cabinets that did not include a crossover of their own? I know there is a debate on active vs. passive xovers, but I didn't think anyone recommended both.

The balance is correct on these files when I play them through my sound card. Also... All other sources on my system are balanced correctly, so the finger points to the SB3... I am sad to say.

But left and right should be calculated the same way, so you'd expect them to match if the levels match. Fezco, have you measured the analog outputs with a meter? Have you tried playing a test tone?

Can someone from Slim comment on what they have experienced with FW 29 -- why it was injected into 6.2.2 so late in the game and what the deal with the stuttering is? 6.2.2 looked like it was poised for release and this new FW seems to break what was once a very stable branch for a lot of folks.

Are you saying that the VU meters on the Squeezebox show that the left channel is louder? I would expect those to register the levels in the digital data, and it would be very odd indeed if the Squeezebox were digitally boosting the level of one channel and not the other. A bug in the firmware or the slimserver, or perhaps the level bias is intrinsic to the tracks that you're testing with. What version of the firmware are you using? What version of slimserver are you running? Have you examined those files in an audio editor? What format are the files you're trying to play? -- John Stimson John Stimson's Profile: http://forums.slimdevices.com/member.php?userid=218 View this thread: http://forums.slimdevices.com/showthread.php?t=20964 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Get the balance right
That's very strange. Is this coming from the analog output or the digital? I'm assuming from your equipment that you're using the analog outputs, in which case we have to determine if the files are like this at the source (unlikely) or if they are being mangled by the SB. Try to play the files in a computer audio player. Odds are they are fine. If they're fine in the computer, try another sound source on that preamp input. Make sure to swap interconnect cables too. If that's fine as well, I'd say you have a defective SB. Confirm this by listening to the headphone output. This must be a very rare failure though. fezco wrote: > Greetings SqB3 meisters.

The PAR-0530 is not suitable. It is rated at 0.3 Amp which is nothing like sufficient for the Squeezebox. The PAR-0510 has the best spec at 1 Amp, which may be enough, you will have to try it to find out. I can confirm the CPC power supply is linear - I've had a look inside it - and it is rated at 1.5 Amps. I can also confirm that mine and the two others I know of are working well with S/box 2 and 3. -- afblaster afblaster's Profile: http://forums.slimdevices.com/member.php?userid=1643 View this thread: http://forums.slimdevices.com/showthread.php?t=19452 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Not withstanding M3Rocket's comment, the Squeezebox smps wall-wart is rated at 2Amps (10VA), but the CPC 1.5Amp (7.5VA) linear supply works well with the three players I know of. In comparison with the 1Amp (5VA) Power Pax, the size and weight of the CPC unit is substantial, and it's too large and heavy to use as a wall-wart if it had been constructed like that. This suggests to me that the Power Pax transformer may be a tad undersized and working at the limits of its spec, if needs to supply 1Amp continuously to the player(?)" With regards to the Powermax model, wouldn't the next model up part no: PAR-0530 from http://www.powerpax.co.uk/ac_dc.htm be sufficient? It has output voltage of 5v and ampage is 300 (mA).
