Not crackles, it usually manifests as Audirvana just giving up playing a track and skipping to the next one. This only happens with 192kHz tracks, and only on my old computer. Converting these files to 96kHz using XLD works as a solution for this, but what I really want to know is are there any...

Thanks, but I've narrowed this down to an old computer (2009 Macbook relegated to hifi duties) CPU/Memory/USB2 issue. On my 2015 Macbook all my cables (both optical and USB) are 100% fine playing at 192kHz. I really don't think I can hear any difference between 192kHz and 96kHz but I'd like to...

Hey @Rob Watts apologies for quoting an old post, I'm just wondering if you could give your opinion on converting 192kHz files to 96kHz using something like XLD? Assuming I'm using one of your DACs, is there any downside to this? I'm also having occasional problems playing back 192kHz files.

Pause the music and turn your amp up to full, and listen to what the tweeters are putting out. Then replace the iPower with a regular Apple iPhone charger and see if you get the same. I also tried this on some Mackie active speakers and got identical results to the Mojo/Naim set up. Whilst I...

My experience with the iFi iPower is not "really good". Whilst it may supply clean power to whatever it's powering via USB, it kicks back so much noise back into the mains it's not really usable for hifi/speaker applications (would be fine if you're listening to something like a Mojo/Hugo via...

I was under the impression the super capacitors on the HugoTT were essentially to help out the battery on power supply duty, not to beef up the analogue output stage, is this not the case? I can kind of understand how this would help re driving difficult headphones, but if you're just feeding an...

I'm sure you could replace the power supply with whatever you want, the fact it would have to be terminated with a micro-USB connector really shouldn't make a difference should it?

Supplied charger is 5v 2A So I'd imagine it needs that. What's the problem with a Micro USB connection?

@Music Alchemist Ah @ChordElectronics updated this, originally it said £1995.

No, signal is on the larger USB connector on the left, power is on the micro-USB on the right, you can tell this by the little lightning 'power' symbol.

£1995.00 ?!

"A further new feature is a user-selectable output voltage available in 1, 2 and 3V RMS outputs for flexible connectivity with partnering devices."

Some UK Chord dealers have been dumping 2Qutes on eBay at £795 this week, I'd expect the announcement to be the 3Qute.

Yep: Thumbs down. iPhone 6s, iOS11, Mojo attached via Meenova cable: Played music for about 1 minute before freezing and 'accessory not supported' popup. Maybe it works with the CCK, but this doesn't bode well.

Even though I use cheapo Fisual cables (about £5 each) they work fine at 192khz (never had a single dropout/issue) with my newer Macbook Pro, and also the X-USB. The problem is that Apple didn't support these rates until after 2013: https://support.apple.com/en-gb/HT202730

I'm using an older Macbook that only goes to to 96khz over optical (and won't do 88khz either) so to get around this I bought a SMSL X-USB to convert USB to optical. Sound is great and interestingly Mojo no longer auto shuts off, so obviously the auto shut off thing is specific to certain...

Hmmm, John Franks in the Poly thread: "Because at present Poly can only be switched on by being connected to a Mojo that is switched on."

I wasn't aware that 2tb Micro SD cards even existed! I'd imagine they're pretty expensive... I'm not interested in Poly for a few reasons: 1. It's £500. I'm not saying this is bad value, but I just want a DAP, I'd be paying for a load of functions I'd never use. 2. As a DAP it requires an iPhone...

The Meenova lightning-usb cable works perfectly with iOS 10.2.1 (it's cheap too), I'd really like to know if it works with the iOS 11 beta (anyone?), but I'll just wait and see on that. If this doesn't get resolved soon I'll probably end up buying a cheap DAP, can anyone recommend one that...

Yeah it's total nonsense. In fact, many many people have asked about using Mojo in this way (i.e. using as a DAC in a hi-fi) and the ONLY issue that gets mentioned (by John, Rob or anyone else) is Mojo's lack of galvanic isolation over USB. If this particular use case is problematic, why...

@Chikolad I think it's different, in that under #3 'charging noise' they basically say that's it's not Mojo, it's the charger, and if you change to better/charger cables the noise will go away. I've tried short 20AWG cables, Anker Powerline Cables, and the supplied Mojo Cable, none of these...

We don't know, and this is what I'm trying to establish... By looking at some of the posts from QR coded units on here it would appear that there is some sort of problem with a number of units. At least one person with a 49xxx unit has said their's doesn't make noise, so *maybe* it's been...

@mswlogo Yep, hissing is from the unit itself, not through the headphones. In at least a couple of examples (and probably others), playing music actually reduces the noise.   @Chikolad I believe if the unit was on, then your Mojo would probably continue to make noise. Like you say, if it's...

@Music Alchemist As far as I can tell all the users on here with this particular type of noise (when it's in trickle charge mode) have all had the later QR coded units, mine were 46xxx and 47xxx.  I suspect there were some internal components changed at some point around the time of the QR...

Yours is worse than both of my bad ones, mine have been more of a hiss than a whine, but it's the same in that it's much quieter when music is actually playing.
