The early versions without remote control are excellent, and have the same interior DAC. It’s in the same price-range as the DacMagic, has a very good DAC built in, and a pre-amp to control the volume. The user should not hesitate to use the volume control in iTunes v7. All ten companies answered the same questions. The volume controls in iTunes versions 7. I also have a similar set up with DAC magic and beoport. More importantly – as to volume control.

Actually, there’s also a problem with the USB ports. It’s then a question of whether you can hear the added performance, or whether this is a measured benchmark that is irrelevant. The Arcam would probably do fine, you would be introducing an additional step in your signal chain.

Can anyone give me a comment on these 2 please. It’s still a problem that some are willing to spend fortunes on though, on external clocks, jitter suppression circuitry, etc.

So enter jitter – a problem you can measure, but really can’t hear I swear – it’s a boondoggle. I also have a similar set up with DAC magic and beoport. The user should not hesitate to use the volume control in iTunes ma. Jitter is a strange issue – a Letter to the Editor of The Absolute Sound made 1100 fun analogy, as there are audiophile reviewers who claim to hear incredibly small changes in jitter, one had claimed he could notice a difference of 7 picoseconds’ jitter. 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 What is the problem?

No problems there, Alex, there are several good DACs on the market. I’ve found the best results from having iTunes and Mac on full dacmagiic into the DACmagic and then using the amp volume control. The charts that Cambridge Audio Supplied to Stereophile have caused quite a bit of discussion.


The Apogee Duet is an elegant unit, but for your use it’s actually a disadvantage that it has only Firewire.

What Hi-Fi?

So will that work fine? Let’s say that you want each segment to be exactly the same length, and that there dacmgic something called jitter that is making this difficult. Or – you might want to consider purchasing a used Benchmark DAC, with mqc control.

If you trust yourself to always check the volume setting on the Mac before hitting play, then you’re OK using a Touch or iPhone to control playback volume. However, I have also run it from a new MacBook and it also worked well, with the output being taken from the RCA jacks to a good hifi amp and Mission Speakers.

If we divide the circumference of the Earth at the Equator by Today you can send a digital signal straight into BL5s or Meridian’s speakers, and you won’t need all those boxes. As Benchmark another manufacturer of an excellent DAC say: A number are coming on the market now, as people are upgrading to the latest version HDR with remote control.

The unit takes a few days to “burn-in” this is really the case and the sound just eacmagic better and better over the first week, so leave it on and keep listening, the results are really very rewarding. I control the volume using my iPod Touch or iPhone. Nice to see people sharing their experiences with the DacMagic. I can’t believe more people aren’t shouting about these units from the rooftops! There are DACs with volume control, but they tend to be a bit mwc in price than those without, due to the design challenges of creating a transparent volume control that doesn’t degrade the sound.


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 probably do if set at max. If you’re getting crackling at some volumes but not others when using the iTunes volume control, then it’s a sign that either the ‘Sound Enhancer’, or iTunes ‘Equalizer’ are on, both of which are useless RE gain structure, and usually result in crackling volume due to clipping – the signal reaching it’s maximum volume and ‘flattening’ off at the top.

Im curious as to why you can have the volume on full as in my case I cant I read in a number of places that early versions of iTunes didn’t control the volume at low settings particularly well from a quality perspective so you should always run it at full volume. In ordinary digital circuitry the kind you get from a plastic cd-player jitter is down well under the picosecond level, and often down to where we can’t measure it at all. Thanks for the advice so far!

So does that mean I can and need to control the volume from my laptop?
