Cool that will be a good match up What chip is in the yulong
As Michal and I have discussed ad nauseum, for a budget of $1500 they had to make sacrifices, and one area IMHO, is the variable analog stage. It suffices, but is wayyy better (again IMHO ) in bypass mode, which then requires the user to use a preamp or integrated amp (or active speakers, etc). Also, as a Mytek-defined preamp the analog ins are clean and would suffice for someone who primarily listens to digital but needs a secondary analog source for those few times.
I'm using the Mytek with a preamp but I'm tired of the very high output level
Did you use the internal hardware gain jumpers to lower it by 6dB?
Here is how it is better in description . In my office I have a speaker rig large speakers . When I first set it all up I quickly used the mytek as the dac and preamp. And I was not happy with the sound, it is almost smeared , it lack body. Dull sounding . I thought it was my speakers and was not happy at all and really pisssed off. I had remembered reading an article about the pre amp and how much it improves with out tit. So I used another preamp and wow what a change . And the change is not my other preamp it's just the way the dac sounds in preamp. I am not sure if it is the way the volume control is done or what . Now further more the internal headphone is ok . But after you use
The dac with another headphone amp you will get a feel for the issue.
Google the mytek and read it is not a myth it is real. One more thing the USB and FireWire
Sound different too. As for me FireWire is better , but I'm sure this changes with Cpu used.
I read somewhere that the resistor on the headphone amp output is 20 ohm, but looking at the resistor that is bypassed, it is actually 5.1 ohm resistor, not 20 ohm. So if it is 5.1 ohm, than the total impedance with 32 ohm headphone will be 37.1 ohm, so the max power is higher than 1.18 Watt.
It's a shame Mytek doesn't report the headphone output impedance clearly. Is it 20 ohms or 5.1 or what? To me this seems to be the dealbreaker, because I don't really want a separate DAC + hp amp if I'm spending this much money. The headphone output impedance 'rule of thumb' is below 2 ohms (NwAvGuy) and 20 ohms is just too much.
He also said the 20 ohm resister was put there from people who blew up the output op amp by shorting it. He also said with headphones it would not matter at all. The headphone part makes sense since it is just a bit of attenuation to the headphones. But he did explain I was not the first person to ask about the IEM,S. .
