Mytek Stereo 192 DSD DAC/Preamp/Amplifier Thread - Page 11

Not sure what other buffer you mean, other than the settings for the FireWire device itself, in device settings? 

 

I worked with Chebon, presumably from the Brooklyn office, who got me the older driver. He was very helpful.  Older driver worked but I ended up switching to USB just to avoid the mess.

Ok I understand , I be leave in the windows control panel under devices there is a buffer setting as well. Also that is Brooklyn 718 area code rifght? Fire wire does sound better though to me and they told this as well. Wow I am wish I could help you.

I talked to Chebon about the firewire.  We both had read the same review that stated it sounded better, but neither of us had heard it.  I should probably do a listening test.

I read it and tested myself . It is defiantly different and I feel better in definition . It's not amazing but if you A/B you will hear it . Do the test with a simple song just singing and Tatar or small jazz , use a known recording of yours. I'm sure you will hear it.

Do you mean clicking noise when you turn the volume knob? Mytek use analog step attenuator as one of the volume option, it is normal to hear soft clicking noise when you turn the volume knob, when you choose the analog volume control. In digital volume control, there is no clicking noise.

Dear Sirs,

 

what do you think about Mytek 192 vs Zodiac Antelope Silver + ps? Any test?

 

thanks :-)

No, this was something else entirely.  Definitely a driver related issue with a specific machine.

I'm tempted to do the same mod, to short or reduce the value of the headphone output resistor.  If I'm looking at the right part, below as shown in the picture, it seems like Mytek use TPA6120 family as the headphone amplifier.  20 pins chip.  And according to the schematic of TPA6120, output is on pin 2 and 19, which connected to 20 ohms resistor in Mytek circuit.  According to TPA6120 datasheet, output resistor is required for the amp stability, to reduce the parasitic capacitance on the output.  Minimum should be at least 10 ohms.  So I'm not sure whether to short it, or reduce it to 10 ohms.

 

Could you please confirm that I've circled the correct headphone output resistors ?  Thanks!

 

 

 

 

Hi good Sir. Did you ever figure out if these were the right resistors and did you end up shorting or replacing them with 10 ohm ones?

However I brought my unit to there shop in Brooklyn ,ny USA. I had them shut the resistor . And it gives more bass detail as it helps with the damping factor . The resister is on the left side facing the front when removing the cover. It also helps greatly with low impedance IEM,S or headphones. It is a worth doing mod.

Pm me if you need pics I will open it up and take a pic to show you what to do.

Also if you here artifacts useing the USB . Increase the buffer in windows . This helped me greatly . Until they gave me this info I was using FireWire as it was clear with no artifacts.

I hope this helps some people here.

Thank you for the tip, but could you please help us out with images here in public, or maybe respond to earfonia's questions above?

Thanks a lot! ;)

 

BTW, just FYI, I've upgraded to firmware 1.75, everything seems ok, and I didn't notice any changes in the sound signature.

I'm glad your ok now , enjoy great product. If you have other amps try the dac output it is better then the internal amp.

The amp in the Mytek is seriously good, at least at moderate (85-90 dB) listening levels IMHO.  I think it could support many headphones just by itself.

I wonder what kind of power output the headphones output has with different loads. I've asked Mytek about it in a ticket, but they didn't respond to that question. However, and to be fair, I did ask many questions where everything else was responded to, so they might just have overlooked it.

 

Does anyone know how many mW it puts out on different loads, or should I start naggin them for real? Haha.

 

Edit: Mytek have responded quickly and extensively to all my questions, so not trying to put the company down. I'm very pleased with both customer service and the product. They probably just missed the question.

I haven't seen measurements anywhere and I looked around a lot prior to purchasing.  Most reviewers were complimentary though with comments like the following:

 

 

I did some informal A-B-X  against my Master 8 and I think its pretty impressive.

Digging back through the product reviews I just saw this:

 

 

Has anyone tried the filters?  I didn't even realize they were there.
