Unless they've made a major change, I doubt the iDSD Pro is mirroring the DP-777 in that regard.  The "Quad Core Dual Mono" is just a fancy way of saying they are using 4 DAC chips, where each chip has a mono output in a 4 channel, balanced out configuration. (each chip handling half a phase of left and right channel).
Being a current satisfied Mojo owner, this updated Hugo also interests me.  Assuming the retail price doesn't get too bloated.  It does seem like the Hugo 2 should offer better value than the previous one at about the same price.  I think around $1800-$2000, it could be quite competitive.  I've always liked how Chord can squeeze out performance out of a limited physical space.  There's a certain design efficiency that I appreciate as a future prospective engineer.   Like...
Given that this thread is in the source component section, and a thread for the Pro iCan exists seperately, I've edited the title to reflect focus on the Pro iDSD.
I will try to get it shipped to the next loaner recipient tomorrow, assuming no Snowpocolypse issues here in Michigan.
Here is my review for the loaner program.  I am going to try to also post it to the reviews section, but the upload was giving me an error.   First of all, special thanks to Todd at TTVJ Audio for the opportunity to participate in this loaner program.                      Introduction:   The Sangaku is the first Apex Hifi product I have had the opportunity to audition.  It is one of, if not the first headphone amps to utilize the new Korg Nutube, which is a...
In your case I'd say the Stax. If you don't feel an appreciable difference between the Modi and onboard sound, you will likely be disappointed spending the money on a higher end DAC. Or it could just those headphones aren't resolving enough. In any case, you could try the Mojo first with the Koss and see if you like it and the Chord house sound first.
Are you using with the iDSD? I found the presentation to seem a bit recessed in a similar way the Elear is already recessed. It may not be an ideal pairing. If you are willing to try parametric EQ, try something like +5db, 4.5khz, Q=16.
So, I normally hate to hype up simple tweaks, but I decided to put Rob Watt's claim that the Mojo is essentially immune to jitter, but sensitive to RFI to the test.   It's USB related, and cost me all of around $10, but made a fairly dramatic difference.  Different enough for me that I was originally going to give a lukewarm review to an amp I have on loaner, but the amp was only being transparent to source (for the most part)   It's basically taking a generic but...
This isn't my personal experience, but taken from a quote elsewhere from a respected amp designer.  This is from user DSavitsk, of ECP Audio and the Torpedo DIY amps. "Basically, the Focals behave a lot more like a traditional dynamic speaker in terms of impedance while pretty much every other headphone doesn't. That means that output impedance makes a big difference and really needs to be kept to a few ohms. In essence, the headphone impedance creates a voltage divider...
This is odd. My HD-650 is modded to be less dark than stock, and after adjusting to the sound of the Elear, the 650 sounds muddy and veiled in comparison, without readjustment.I have read however, that the Elear is sensitive to amplifier output impedance. That it needs to be no more than a few ohms. Too high and the impedance curve will boost the midbass significantly. This could be a source of varying impressions. The Mojo and the Sangaku I have in loaner both have...
