Chord Mojo 2 Thread ___ [product released January 31, 2022 -- starting on page 95 of thread]

Some cables are designed to only supply power for recharging. Some are data and power. Just make sure it passes data.

Pretty sure I watched a review where they were using an Audioquest Carbon lightning to USB-C. Apple cables are charge and data as well

Are you sure that’s not a Roon limitation? You may be right, but I haven’t seen that limitation stated anywhere for Poly using WiFi.

My apologies. You are correct. Confirmed with 768khz PGGB file streamed through mconnect.

I am using HQPlayer and upsample 44.1 kHz 16bit tracks to PCM 705.6 kHz 32bit with Mojo 2, music sounds very smooth. In my experience, this is as good as it gets. If you use Mojo 2 with a computer, you must give HQPlayer a try if you have not (much cheaper than M-Scaler) Technical ability of Mojo 2 is amazing for it's small size. Really happy with M2

Anyone compared Mojo 2 with iFI Diablo. I know Diablo is twice the price, but still interested in the audio quality differences.

I own ifi Micro DSD Black Label. I auditioned Diablo before buying Mojo 2. Diablo packs power but the sound signature of Burr-Brown chip is there. So if you like that then go for it as it can drive pretty much all cans out there. However, I found burr-brown sounds a bit slow and mundane. I much prefer Chord's PRAT and dynamic sounds (some may call it dry or analytical). Also, the volume knob on portable ifi devices do not track evenly at lower volume. It needs to get up to a certain level to have equal volume. This may be not an issue for you if you don't listen at a low volume. Mojo 2 has a very good amp and volume, IMO. I cannot hear any distortion at any volume level and it tracks evenly. I was not very impressed with Mojo 1 but Mojo 2 did!

Did I mention it has Milf Resistors ?

Very good... but MELF resistors are hideously undesirable, (more of a Siren than a Milf) as they have internal pressure contacts from the solder caps to the metal film resistive element which degrades detail resolution and depth perception. Imagine replacing a gold RCA phono socket with cheap tin plated contacts, and do it many times over - that's exactly what you are doing when using MELF resistors. They also have another problem, as the metal film is printed as a spiral on the ceramic cylindrical body; that gives it large value of inductance, and together with parasitic capacitances creates significant RF resonances - adding to RF noise and so more noise floor modulation. Metal film SMD resistors on the other hand have fused silver palladium internal contacts, so no contact non-linearity problems, and minimal inductance and parasitic capacitances, so almost perfect RF characteristics.

Mojo 2 dry or analytical ? I found it to be a bit on warmer side despite having extremely good transients. Prat is not always analytical you see. There were times when prat was synonyms with bright analytical sound but not with chord dacs. Chord dacs sound 'faster" due to lack of distortion and accurate transients not because of analytical by nature. We audiophile like to describe sound as some "type" like slow fast, warm, analytical etc etc instead being accurate or inaccurate. Imo chord mojo 2 is more accurate than that burr brown. More accurate sound is more life like, it is as simple as that.

Neither Mojo 1 or Hugo 2 was emotionally engaging when I had them. However, I really enjoyed Hugo 2's PRAT. I am not sure what's different about Mojo 2, but it sounds so right to me (with Roon / HQPlayer) and I do not have desire to try TT2 which I was looking to get later this year.

Would you mind sharing your Roon / HQPlayer settings?

 

[Jeffyue]

Anybody can share the experience between Mojo2 & Centrance HifiM8v2?

Hey guys, exploring my coax cable options for the Mojo 2 in advance. I was about to get another 1694A Beleden BNC cable from BlueJeans Cable co. which was excellent for the Qutest, but due to it's thickness they recommended slightly thinner cables to fit one side onto the required 3.5mm coax connection for the Mojo 2. First they recommended this but I wasn't sure due to it being stranded copper, which is odd for any BNC type cable. Luckily they got back to me after checking around and look what they found: a silver-plated solid copper core cable. Just wanting any feedback on my options. This will go between my DDC converter and the DAC (one side RCA, other side 3.5mm coax connection)

The most important part of music to be emotionally engaging is focussed vocals. When vocals are locked in centre, while music is all around you, imo is the best situation for vocals, communicating directly to you. Chord dacs with ultra low distortion and nil channel imbalance (due to digital volume control) are main contributer to this trait along with accurate transients.

Yes, yes MELF resistors ( damned spell-check's Add to Library ).
Bottom line, the use of these resistors here, is just for a colourful sales brochure, all those colourful rings!
I get a little apprehensive, when any manufacturer starts to quote the opamp model numbers, DAC chips series etc. To me, it says "we are filling the void of low-design by exotic components".
ifi is a respectable company, they should avoid that, but these are Covid days, economy not what it used to be.

Would you mind sharing your Roon / HQPlayer settings?

I tried many different combinations of PCM filters and dithers, and bitrates and modulation for SDM, the one combination I really like, and always comeback to is sinc-M / NS9 with PCM sample rate 768K. I grey check Multicore DSP and Adaptive output rate. My tracks are mostly 44.1 kHz 16bits and this setting sounds great with all genre of music with Mojo2.
