Everything feels constrained out of the headphone out, frequency extension is limited on both ends, and the bass is significantly less textured.  A lot of detail is smeared, which really detracts from how holographic the DAC really is.  

 

I ran this test on a pair of JH13s, Grado RS1, and Sennhesier HD800.  I heard similar differences on all three, which leads me to believe that it's not an issue of current, but of design.  I suspect the headphone out on the Mytek is a bolted on chip amp, and while it uses the same excellent power supply as the rest of the unit, it's not designed to the same standard.  This unit is designed as a DAC first, preamp secon, and headamp third.  If you can get away with using only the DAC, it's a great unit.

I have the same opinion.  I guess it is not minority opinion.  I have both Mytek 192-DSD and Yulong DA8, and Yulong DA8 headphone output is far better than Mytek's.  Mytek headphone output is bass anemic.  Bass sounds thin and dry compared to DA8 headphone output.

Not unless either Audirvana builds a windows client, or I figure out a way to install a SoTM card in a mac pro.  I haven't bothered hooking the Mytek up to the macbook or the mac mini, because they serve other functions in my home.  I haven't used JRiver's mac client, and I like Audirvana a lot, but I've never liked a piece of playback software better than I like JRiver's JRMC 19 for windows.  It is a joy.

 

Incidentally, the SoTM card (http://sotm-audio.com/english/products/tx-usbexp.php) may have something t do with why I prefer USB to Firewire.  I would give firewire a fair shot with a similar card, but there's nothing comparable.  I got a high quality PCI card, but even then it does not stack up.

Did you compared the dacs using speakers?

Good question ... I have headphones, ciem,s and speakers . And although I love headphones speakers seem to review more about a dac , even though headphones do to if it's close speakers will be the judge..

No, only headphones.  I use the line output with Violectric HPA-V200 headphone amplifier, I would say both are very2 good.  I need to spend more time to be able to give better impression of both DAC using external headphone amplifier connected to the line output.

 

As for the headphone output on the DAC, Yulong DA8 headphone output sounds much better to me :)

I am not surprised as to what you have found. The headphone amp is ok but a little on the blah side of things. It is a little better with iem,s. But generally just ok. But as we listen to others we realize quickly what we are missing.

I've updated the unit's firmware, gotten the latest drivers, and carefully arranged data cables to be as far away from power cables as possible.  I'm going to give the firewire input a fair shot now that everything in the rig is (basically) set.

 

Anyone have recommended firewire settins for JRiver?  is anything preferred over ASIO?

INCREASE buffer size in firewire control panel on desktop.

Sherwood. that is a nice usb board. where and how much???

Just did a temporary mod of shorting the two resistors in question and the difference is very noticeable (fuller, more detailed bass and less "restrained" sounding) using my JH13s. And I'm one of those firm disbelievers of much of the audiophile snake oil that plagues the Internet. From experience, I'm guessing the difference will become less noticeable the higher the impedance rating is on the connected phones.

Don't do this if you don't have experience soldering components and talk to Mytek directly about possibly voiding the warranty.

And be prepared, that you might kill the headphone out because of a short circuit, while you plug in your phones. The 1/4" TRS jacks can short the contacts of your 1/4" female connectors while halfway inserted, and thus overloading and breaking the headphone preamp circuit. That's the reason for the extra resistors.

i am glad you liked it, its a shame it needs to be modded, but it is a big difference . the jh16 is even more of a change..

I'm guessing the Roxannes will be an even bigger change since they're only 15 ohms.
post #194 of 343
Well it is only 1 ohm . But at least it will sound its best now. The amp has a noise floor issue to, but it stops when music starts. I asked mytek but i have not found a cure for it.

Sorry, I missed this until now.  I picked mine up from Smallgreencomputer, who specializes in such things.  It was $350.  They can be had used cheaper from time to time, but they're rather rare on the used market.  One on Audiogon for full price right now, I believe, which is crazy.
