all cables checked and are correct

you have checked that the cables connect the right sockets.

there is the potential chance that one of the cables is incorrectly wired internally - is it possible for you to use any spare duplicate cables, to check if changing any of the cables, solves your problem?

im using spotify premium from macbook pro via aitport express no other program involved.

so that is the same software source frontend, for both the irdac and mojo?

im not aware i can its in line level mode i dont think you can change the sampling mode.

regards

I think you can set your Mac to upsample from 16/44.1 to higher, for example 24/192.

This is just an experiment to check if it's a firmware bug.

Q. Do I need a driver for Macs? (OSX)[/b]

No. OSX supports high-res PCM playback. You will want to match the output sample rate with the music sample rate. You can set this in Audio Midi Setup. Many "audiophile" players (Audirvana Plus, Amarra, VOX etc.) will auto-switch the sample rate to match the music. You don't want OSX re-sampling the music!

Alright, you guys sort it out. Too many chefs in the kitchen this way. Mike knows what he's doing.

 

[The Mad One]

If this is a problem with the mojo with changing adjusting sotware then im sorry id rather just stick with the arcam ir dac even though its clearly not as good.

but its its simlpy plug n play then so be it.

canot be bothered with this hype of a better sound if your prepared to fanny around for an age to get it just so,

i don't know about that!

i am just good at searching for the obscure answers to engineering problems.

I had this problem with my irdac using Apple devices connected to it. I contacted Arcam and they were aware of the problem. They claimed Apple made some changes that led to the channels being reversed. I downloaded the latest firmware for the irdac and problem sorted.

I do not have this issue with the mojo. Do you have the latest firmware on the irdac. Maybe you've been listening to the irdac wrong way around all along which now makes the mojo seem wrong even though it may actually be right?

An Arcam iPod dock I use also has this problem but firmware can't be updated. Easy solution, swap the cables.

Interesting

Turns out it could be the irdac that was doing the channels in revers and the mojo was doing it right.

i think you should get a Mojo Vladimir. You always express a keen interest in it. Would be great for your new set up.

My active desktop speakers accept balanced connection via TRS or XLR. I'm sure you could see how a battery powered portable DAC with unbalanced 3.5mm output is not the ideal solution here.

Also I have no hi-res music, I just stream via Tidal (320AAC) and Youtube (192 MP3). I wouldn't use the Mojo even if I had it laying around. The Lexicon Alpha is much better suited in this application.

You could get rca adapters maybe?

 

[Vladimir]

3.5mm is a compromise in connectivity and too fragile. I prefer my hefty Neutrik TRS-XLR double shielded professional cables. Plus I get a balanced connection.

Ideally I would use a Benchmark DAC2 HGC.

And it has a remote!

OK

Ive just spent an hour pulling my hifi apart disconnecting all cables then one by one put it all back testing each bit of equipment as i go using the same track until finally ive found the culprit.

its the bloody QED J2P Cable it must be wired round the wrong way weird. *diablo*

But hey at least its not the mojo or Amp

Apologies for the rant yesterday but a few glasses of wine and i was beginning to wind myself up and couldn't se the wood through the trees as they say. all could think of its the Mojo thats at fault, so being sobered up its all sorted and now im well enjoying my music although im sick of listening to Early mornin'rain *wacko*

P.S

Anyone thinking of purchasing the chord mojo youll not regret it, its fab *good*

you see how easy it is to make a simple mistake i done it myself ... glad its sorted *good*

Sorry if it seemed that I was asking a never ending list of questions last night, but I was just trying to eliminate possible root causes of the problem - one by one. *biggrin*

I'm pulling your leg sorry. To be fair you stayed calm!

Perhaps for balanced output you could sellotape two mojo's together, double the love!

That would be like a whathifi 10 star rated dac then, be quite expensive so obviously better than anything else you've suggested.

I use USB 1.1 isochronous interface at 16/44.1 for streaming lossy music online through a pair of cheap and plastic Chinese made JBL speakers, connected with microphone cable, sitting on improvized stands.

Unfortunately the amazing details, clarity and vividness coming out of the Mojo will get suffocated and lost on my low fidelity setup. But some day when I purchase high fidelity speakers and amplifier, I may get a Chord Mojo and run it only on battery so the sound is super super clean.

As said I was joking with you. I've no doubt your system could teach a few things about unesseccary hifi expense.

To be fair to Chord though what they charge for the Mojo vs what they could have charged is a very encouraging step in the right direction for a hifi manufacturer imo.

The unanimous positive press it's receiving is at least an indication it's doing nothing terribly wrong as a dac. Personally I can't agree with the "all dacs sound the same" mindset of some, they simply don't. I've been through a few, all well reviewed, some expensive etc and in the mojo I've found an excellent performer regardless of price or reviews. Neither high price nor reviews led to influence my mind, otherwise I'd be a delusional owner of a £1400 Chord Hugo or worse.

 

[Vladimir]

I want that Benchmark DAC despite it's price exceeding a Chord Hugo. It's well made, good features, can serve as a preamp and it has studio alure to me. The flat neutral colorless digital sound is not what creates majority of the appeal. I can get that from 10 or 20 times cheaper gear. It would be an irrational purchase as much as any in hi-fi.

People who like small pocket and portable DACs will like the Mojo, or Hugo, or Meridian Explorer, or Dragonfly etc. The battery has its extra practical use. It is a valid product, but not for everyone and every application. In this instance, not my application. I object its toyish looks but that has never stopped me at getting something I want.

 

[ChrisIRL]

I know the mojo would be completely unsuitable for your application.

For me it is all about the sound, nothing else.
