So should I end my curiosity for balanced. If it's not audible then I guess what for...

It's audibly better for me but certain factors has to be in place.
1. Your source has to be recorded in stereo (this I've heard personally on a Beatles and beach boys album) and the imaging is superb.
2. Noise floor is almost mute for most cases in balanced mode.
3. Impact is better as the separation is better heard (expounding on point 1)
4. Detail and depth lifts up as each ear hears something different.

On a good recording though they could simulate a stereo image but it's not quite the same especially depending on what genre you're listening to.
That's my take so far :)

Since many Mojo owners use Jitterbug, I thought I ask this question here.
Do you think, I should give a go to Jitterbug even though I use a very well shielded, quality USB cable with 'floating internal ferrite jacket', which is said to decrease jitter by 50% compared to cables without the ferrite jacket?

Rob has said many times that the Jitterbug doesn't reduce jitter with the Mojo as the Mojo is already pretty much jitter immune on all it's inputs (you can read Rob's posts for detailed information regarding how/why). What it does do with the Mojo, and even the DAVE, is reduce RF noise entering the system which he says hardens the sound and flattens the depth. Rob did a test with the DAVE and with his laptop running on battery power he could not discern a difference with or without the Jitterbug in the mix. However, with the laptop plugged in to the mains he did hear a slight (emphasized slight) improvement in sound that typically comes from reducing RF noise in the system.

That was with the DAVE which is already galvanically isolated on it's USB input. With the Mojo the benefit may be stronger because Mojo does not have galvanic isolation, but it isn't from reducing jitter.

So, in the end, if your source is introducing a lot of noise in to the system then the Jitterbug may be a benefit. I'm also not sure if it will help with cellular signal noise as that can enter the Mojo even through the headphone cable (as I've tested myself). FYI, the ferrite jacket shouldn't have an effect on jitter at all as it's simply a passive choke for RF noise, not an active clocker in the path.

Sorry didn't think it was a big difference, but yeah balanced supposedly cancels out the noise floor yeah?

Is that why a lot of people say that they can hear increased hissing with balanced?

Nope. A fully differential balanced topology may lower the noise floor, but it doesn't 'cancel' it. It should cancel introduced noise in to the system but it won't cancel the noise floor.

Slightly off topic but not for me.

Relic, I get the impression that you can function well on less sleep than most folk - in my case I need 7-8 hours of good sleep otherwise I can feel a bit miserable.
 
I remember a while back when we exchanged some PM's about food and health related issues - that you were quite knowledgeable on food and general health issues.
 
Would you and others be interested in starting a general health and well-being thread - at some stage in the far future?

I appreciate your help, now for me all sorts of curious

Thinking of getting the chord mojo so was looking around for cases too.
Does anyone have both the official Chord case as well as the Dignis case?
How do the 2 cases compare?
 
Also found this $40 USD Dignis clone from China:

I'm no expert but I'm always glad to weigh in my experience if it helps :) I think we're all in the same pocket burning boat haha if it helps well at least we all discover audio bliss :)
A quick shout out to all who gave reps! I don't know what priveldges it comes with but sincerely appreciate it :) I've learned quite a lot from reading all of your inputs as well :)
