I had not posted anything for a year. There is not much changes in my setup. Just had tried out some diy and bought few small usb dac. That is more to curious about what would the effect as have read good things about it in internet.
I tried made usb cable and change in the power supply of the usb dac. Both bring surprise as it did make changes to the sound. Positive changes. These changes was made to the setup with small usb dac.
The first changes that I tried was to use give an external power supply to the usb dac. The usb dac that I used does not requires external power supply. It get the power from the usb port. In this changes, I cut the small +ve and ground wire in the usb cable. And connect it to +ve and ground wire from a phone charger. This changes was found from internet. And with intention of quick try with external power supply. So, the usb that I used (that had cut the +ve and ground wire) is a cable that bought from computer shop. This change has brought more details in the sound.
Then, I made change to the usb cable. I made a usb cable using cat6 cable and using the same phone charger. The change in usb cable brought more details in sound.
After that, I tried to make change to the power supply. I heard good thing about linear power supply and low noise regulator. But, the linear power supply is is quite expensive; and for the low noise regulator, I do not have enough knowledge and confident on doing that. So, I tried with the ATX power supply from old computer. To surprise, again, this bring more details in sound.
Each changes bring small or some details in sound. It seems there is still area in improvement. But, I do not know what that improvement is until I has made change to it. The next change that I am thinking to try is to add an usb isolator to the setup. I am still looking in that. Besides, I plan to have another enclosure, floorstand, for my speaker driver.
Besides usb cable, I made a 3.5mm to RCA cable the cat6 cable. It seems give clear sound than the normal cable that I brought from hardware shop. If have spare time, some diy on cable and changes in system may give surprise as we may know the effect of it only when we use it in the system.
The small usb dac that I used is UD110v2 dac and a SA9023+ES9023 dac. These dac has different in sound. I have not listen good enough to tell the different. But, for sure, these dac are worth to use especially the UD110v2 dac.
