I’m doing this right now, with playback from a Mac mini to my soundcard. So enter jitter – a problem you can measure, but really can’t hear I swear – it’s a boondoggle. All itunes options also turned off.. That’s pretty good for something that is meters long. Full volume on Mac and iTunes also works best for the BeoPort. If you really need to EQ the sound, use a good external equalizer, like the Klark-Teknik digital EQs which are brilliant.

If you have the time and patience, you should read all the responses look at the bottom for the others. If you reduced the volume, then you would be processing the signal inside the computer. The user should not hesitate to use the volume control in iTunes v7.

Cambridge Audio DacMagic review | What Hi-Fi?

I have an old Arcam Alpha 8 Integrated Amp: Oldest dacmaigc newest Newest to oldest Previous Next. Latest post 6: Can anyone give me a comment on these 2 please.

As for controlling the volume, this wouldn’t be done on the Mac, as the Mac’s volume control is disabled when the digital output is used. You won’t become any wiser, as there’s no industry-wide agreement on anything, but you’ll relax! It’s QuickTime which controls playback on a Mac, iTunes is a music organizer with dacmaguc control interface, but it is QT which does the actual playing.


Even with the worst jitter performance shown above with the power supply creating jitter of picosecondsthe individual segments would vary by at most a couple of millimetres.

More importantly – as to volume control. X will not cause significant distortion. I understand this was fixed from iTunes 7 onwards, but when I set up my system I thought it was logical to run a full volume so 100 not to risk any potential degradation through the software trying to manage the volume.

The Apogee Duet is an elegant unit, but for your use davmagic actually a disadvantage that it has only Firewire. So does that mean I can and need to control the volume from my laptop?

However – I have BL5s, which make it possible for me to set a working volume for them, and I have set it so that whatever source they are fed, they do not blow out my ears or windows which they could dacmahic do if set at max.

I have no explanation as to why this is the case Desperately looking for reasons to get audiophiles to spend money on digital circuits, the industry is turning jitter into a major problem, when it isn’t. Will this be suitable to use with DACMagic as the sound control?? I’ve found the best results from having iTunes and Mac on full volume into the DACmagic and then using the amp volume control.


I see Benchmark DACs going at very good prices, for used units. I control the volume using my iPod Touch or iPhone. There are DACs with volume control, but they tend to be a bit steeper in price than those without, due to the design challenges of creating a transparent volume control that doesn’t degrade the sound. Nice to see people sharing their experiences with the DacMagic.

So then it’s down to whether jitter can introduce timing errors in the playback of the signal – i. That’s pretty good for something that is meters long. The analogy was that if one said the distance around the Equator represented a second, 7 picoseconds of jitter represented less than half a millimetre Any recommendation for the volume control interface then? So let’s try to get this number in perspective.

David Coyne Sydney, Australia. I’d personally prefer not going through the Arcam, so maybe you should look for a DAC with volume control, and have that set at a level where you never risk daacmagic the speakers, and then just leave the volume in the Mac at max. So enter jitter – a problem you can measure, but really can’t hear I swear – it’s a boondoggle.
