GOOD HINT :

I am use my mojo with iphone(6s). Last evening i just download ONKYO player and turn ON it upsampling option.
Wow great !!!! I found that there were huge improvement in sound quality from my iphone +mojo+se846.Actually sound quality improved both flac and even 192 mp3 as well...

Then i google .. And try to find the reason. Then i found that its not new thing and most audiophiles use that technique to improve sound quality.
From theory i found that to get max sound quality you have to upsample integer multiple of original song sampling frequency. For example if you have cd ripped flacs sampling freq is 44.1 so you have to upsample it to 88.2 or 176.4 to get max sound quality.( actually ONKYO player do it automatically)

Hope this will help our friends!!!!!

Theoretical explanations can found here.

I would say you should definitely do whatever gives you the most pleasure

 
 
However, the designer of Mojo has discussed upsampling, previously, in the thread:
 
 
 
i dont believe up sampling will improve sound as the audio data wont change from the sampling method imo

I tried playing around Onkyo settings. Upsampling & PCM>DSD realtime conversion.
 
Upsampling (2n times): I noticed that the whole voicing becomes thinner. I definitely don't like the result. Please note that I believe this is just psychological.
PCM>DSD: Can't notice any difference.
 
In the end, I follow Rob advise. I don't think iPhone SOC can match Mojo FPGA in terms of covert & sample.

Yes correct real time dsd conversion for me also didnt provide proper results.

Just pcm upsample is enough.

Definitely have to give the JBLs a try.
What kind of cabling are you using?
I have a pretty Standart 3.5mm to Dual 6.3mm that would work, but would be interested in impressions with higher quality cables.
Cheers
I'm using this cable separated to each speaker.  http://www.monoprice.com/product?c_id=102&cp_id=10218&cs_id=1021815&p_id=5597&seq=1&format=2
 
Its a good gauged cable.

I like the black CNC'ed aluminum. Reminds me of the faceplates of the old EAD and Theta units I have. I also like the ability to dim the lights of the Mojo. The highest settings are way too bright to be used in a dark environment but the lower setting is just right.




How to dim light on Mojo?

Anyone using a tube amplifier after the magic MOJO with planars to add in some 'pleasing distortion' ?
I'm guessing the Project Ember 2 and MOJO may be a nice combo on older mastering
as well as the MOJO in vanilla direct mode to planars with more technical quality mastering.

that's for the dim light when after power on 2 vol led pressed
for 3vrms its 2 vol led pressed then power on
2 vrms is 2 steps down after the above process

4 clicks lower, not 2, and it's technically 1.9Vrms. :)
