The system set-up I am using currently is Aurender X100 > Modded L.K.S DAC > AMR DP-777 (Pre-amp only, not using the DAC) > DNA Stratus Headphone Amplifier > Sennheiser HD-800.
The Stock LKS DAC before modification was very detailed and had good dynamics and soundstage. Overall it was a pretty good DAC for its price, but I found that it was still a bit harsh and unrefined partly due to the Sabre 9018 chip signature.
Yes, I believe the Mytek is fully burned in now. I left it running continuously for 10 days to be sure. When I received my modded DAC and first listened to it, I was kind of shocked. Your mods seemed to have killed that beautiful bass section, everything sounded tight and very restrained.
I'm just setting her (signature mod mytek DAC) up now, so I'll put some time on her. So far the image depth and clarity is much better with more clean background :)
Tested out my new Premium Modded Mytek DAC with External Power supply. Definitely after the mods it has more details and wider soundstage.
Would like to chip in with regards to MySoundAffairs mod. I went ahead with the full fledged with external power supply mod. In short, it's not magic but the sound quality really went from excellent to state-of-the-art in my opinion.
Thank you for modding my Mytek! After your signature mods, the Mytek gains more resolution and inner details. It is much more analog sounding than previously.
I am still running in the modded mytek. Compared against the stock version, the main difference at the moment is that the highs are clearer and more detailed. The vocals sound more complete.
After the signature mod to my Mytek, everything improved. Vocal is better. Very low floor noise; very quiet system now. Vocal more layback. Actually the change in my sound is quite a big gap. I thought it will be 15~20% change but this is a different league altogether after the mods!
