If all the circuitry is shut down, there is no mechanism to re-start.
So the RF problems (2G GSM buzz) was not RF but audio from the modulation of the RF carrier whilst the phone was communicating with the base station.
This was a problem I could not measure or experience, but Chord could sporadically replicate it. Once realising it was induced audio frequency magnetic fields, I set about coming up with strategies to mitigate it. This worked, in that the problem is now much less - it's at a similar level to Hugo 2 with the mobile phone mounted as close as possible to Mojo 2.
Having said all that, this problem only occurs with 2G - 3G, 4G and 5G do not modulate the carrier like this, and 2G is rapidly disappearing.
Yes. The tip and ring are for the two signals. Note the ring signal is only for dual data mode (M scaler) it is not another SPDIF coax input.
Not quite correct - the total number is 16 times not 15 times. And for 88.2/96 it's still the same amount of processing per OP sample, so the latency in your example becomes 0.35S as the input data is coming in at double the rate.
Taps are taps, the speed just sets the number of cores. So Mojo 2 (for the WTA1 filter only) has 40 DSP per channel (80 in total) running at half the clock speed as per Hugo 2. If it was same clock rate as Hugo 2, it would be 20 per channel, (40 in total). Both strategies give identical results.
Who knows what the future will hold regarding M scalers. My hope is that prices will come down markedly, but at the moment that seems like a dream. It will happen, but more like in the next decade.
So battery life is a complex thing - it's like MPG and YMWV. So I wanted to have >8 hours under all circumstances - IEMs or full size HP, with USB too. (USB adds to power consumption). IEMs are actually worse than HP, as it's current that depletes the battery, not voltage, and IEMs typically draw more current than full size headphones - even though the voltage is very low. I achieved 9 hours 11 minutes with headphones driven loud using USB; nearly 10 hours with optical. With IEMs it was 8 hours 45 minutes on USB.
Proper headphone jack? That would make Mojo 2 80mm wide rather than 60mm wide....
Mojo 2 will give 99.5 dB SPL for the HD800, and 98.3 dB for Stealth. That's seriously ear damaging levels.
Like Mojo, no charger given.
As to whether it will work for you, your best bet is to listen to one.
At the pulse array DAC side, coupling to the OP amplifier.
Thanks for your rapid response Rob.
My question about future Mscalers was actually whether Mojo2 will be compatible with it/those as well?
If I live into the next decade my hearing will probably not be good enough to appreciate further refinements by then.
And frankly, I am as I said so often before here soo happy with my Qutest /HMS both via HEKV2 and my speakers .
I listened to my favourite recording of Sibelius´ 2nd symphony via HEKV2 last night as a 24/96 download Andris Nelson/ BSO and it sounded so good that I could basically forget I was listening to a recording and fully concentrate on the fantastic music and performance.
And this morning I played Anoushka Shankar´s absolutely amazing DGG album RISE via my big speakers and revelled in her fantastic musicality and the exciting and authentic exotic soundscapes she conjured up. Now,to use the term musicality is really justified with her imo.
Only humans and some animals,like birds and whales can possess musicality.
A dac or any other similar "toy" can be more or less transparent, but not musical imo.
My only need for a possible Mojo 2 would be as a lightest possible travel toy .
But I have no need for any of the new equalizing options or crossfeed settings ,only max transparency and enough power to drive good headphones.
Comforting to hear that M2 will drive "REAL" headphones like HD800 and Dan´s Stealth too.? Really? Have you auditioned Stealth yet?
If so,what is your take on it?
But ,what about the quite a bit more difficult to drive HEKV2 which is the headphone I use on a daily basis, will it cope with that one as well?
Regarding no charger I only auditioned Mojo a few times and realized it was not as good as my Hugo1 and was not aware that no charger was included with it.
Why not?
And how to charge it?
Imho a PROPER headphone jack would have been a VERY welcome improvement over Mojo ! 20 mm wider would imo have been a bonus too and allowed for even further improvements with the extra space given.
Well well, wishes and wishes..

Sorry, I just could not resist posting it here again.
One more question though, will it work with both Poly and Mscaler attached at the same time?
I have no experiences at all with Poly and it looks as if a Poly added would block the coax/BNC port?
I will of course audition Mojo 2. But I will not buy one in Sweden where prices will most probably be ridiculously high.
If at all,maybe somewhere in SE Asia next winter.
PS. Enjoy Singapore in April!
I miss it a lot!
If there is an SSO Concert at the Esplanade do make it over there this time,they are really good!
Cheers CC
It reminds me of discussion HTT2 vs Dave: while Dave has more taps than TT2, I still prefer TT2 sound signature for example.
