I have a problem with my mojo. I bought my mojo a month ago. Everything were ok until today. Basically, usb port does not work. I tested with PC, MAC, and Android. None of them can see the mojo. Any idea or suggestion how to fix it?    I have no problem connecting mojo via OPT. 

For anyone interested, this is Bob Katz and Tyll's initial impressions on Yggy https://youtu.be/jtjlUiCFkno?t=52s from 0:52 to 7:21. They also compared Ygg with 'Antelope Audio Zodiac Platinum DSD DAC with Voltikus Power Supply, and 10M Rubidium Atomic Clock ($13,045)'

Check out Yggdrasil measurements http://www.head-fi.org/t/764787/yggdrasil-technical-measurements/90#post_12536283 ....They are close to Dave . Dave still outperforms though! Shhhhhh Dave. However, if you consider the price differences, then you will have a good $$$/quality. Unfortunately, these...

Guys,   One question: I wonder if anyone compared TT with Schiit Yggdrasil?   Many thanks for your answers in advance.

Looks very promising 

You are right. My bad. In all three, apparently there is no dedicated amp (very impressive and well-done chord). Thanks JaZZ for clearing this out. Usually, this is not the case. You want to add a powerful amp, just use the same DAC and add a dedicated chip with a separate board.    Cheers,  Y

First, take it easy . The amp has to be somewhere in the box, there is no magic here. I think we both agree on that. I strongly believe that It is in the second board. It should be something like this http://uk.farnell.com/audio-amplifiers. There is no other place! The first board is the...

Two problems with this:   First, I don't about you, but I would rather have a mojo without case instead of taking every 30 mins from its shell. Then I need to carry both the case and mojo together. When it is cool down, and need to put it back in.    Second, you cannot charge the mojo will...

  A coupe of key scratches here and there. To be honest, it is useless. Don't even bother, spend your money on a dinner much better. Unless you live in a cold place, covering mojo in summer is a really bad idea. It will be cooked like a steak inside your pocket .    Personally, I went with...

Why is that? As far as I know, hugo does not have an amp in it. TT have one build-in amp on a separate board which is attacked to the DAC.    The topology Hugo>external amp>speakers: you will get one amp in the system. The topology TT>external amp>speakers: you will get two amps in the...

'Coloring' is distortion whether we like it or not (signal processing 101). Otherwise, the sound of TT should be identical to hugo (the purest component in the ring) with the assumption that the chips in both systems get exact same input signal.  In TT, since there is a built in amp,it adds...

I know inserting an external component to the ring will add distortion. There is no doubt about that. However, there are some amps currently in the market that are really good. Take Phonitor e for example which has THD & N: 0.00091 % (at 0 dBu, 1kHz, 100 kohms load). I doubt TT will give you 3%...

Internally it is not one board. They are two separate boards and should be. Maybe I am missing something from the pictures, but that what it looks like. Perhaps, someone can post more clear pictures to show how the hugo board is expanded. That will be fantastico :) There is no magic in...

According the website (which I added in the post),  both use Audio Precision SYS2722 system for the measurements. I am not familiar with 2722, but it should consider jitter in stream. Perhaps, someone more familiar with the tool can answer your question. If you are asking why the output sin...

I won't use the word 'cleanest' here. I will say it is certainly the most accurate DAC compared to the other in terms of converting from digital domain to analog domain. In plain English, it is a better DAC as the word DAC stands for. 

I tested Hugo and I have to say there are differences in details and sound stage. Perhaps, the best way to describe scientifically describes the differences is look at the sin waveform produced by the two:   For Hugo: for Mojo: for Dave, because why the hell not :D   here is...

First for most. Yes I have 846 (I love them btw) , but I also have HD800S. So in terms of headphones, we are on the same level.   Second, just look at the picture below: it is the same DAC board!!! and yes wires are used internally to expand the board to an amp. So what wrong with wires again...

  Alright, let's assume I am totally wrong from every possible perspective. Can you quantity how much TT better than the portable hugo? 1%? 10%? 100%? 1000%? and yes you can choose any amp you want, whether it is balanced or not balanced it is all up to you. 

I am sorry but 2600 USD more for a couple of capacitors with better USB is just ridiculous. Coming from electrical engineering background, I know from a true fact the chord didn't spend even 1% of that amount. You may wonder then why Chord puts this price tag? Because the market is stupid enough...

I won't recommend having a case on mojo. The only way mojo dissipates heat is through its aluminum case. Why on Earth you want to cover that? Unlike other portable DACs, mojo tends to get warm.

Fixed :) ... I think it is higher than hugo, just by looking at temperature operation for the FPGA chips in hugo and mojo. The more tap count filter used, the more heat temperature emitted. 

Does anyone know how many 'Tap count' Mojo uses? I can't find it in the specification page.  I know Hugo is 26K and Dave is 164K.

Is there a way to fix that (amp, software, etc)? Perhaps, SPL Phonitor?

Many mentioned there is a slight noise floor with SE846 and mojo pairing. I can confirm that it is TRUE. In the beginning I haven't noticed it at all, but after several tests I found out that there is a very low hass. Still very happy with my purchase    Thank for everyone mentioned that. I...

I wonder whether KSE1500 has a small sound stage like most IEMs? In SE846, you always feel the sound comes from the middle of your head.
