It was recommended that I ask this question in a separate post. Does anyone with a DSD mk1 with or without mods find that they require reboot the dac frequently to get the best sound. I have a fully modded APS version 1 DSD mk1 with analog board and external power supply which I use a Keces P3 power supply. I find that I am required to reboot the dac every day or two or else the dac sounds either dull and flat or it can even sound harsh and hashy if I leave it for several days. I was told that this quirk was relatively common but I h aveI’only heard of one person with this issue and they resolvedd it with a different power supply. Has anyone else noticed this quirk with the mk1?
Am I dreaming (quite possible) or didn’t you get this resolved? The power supply?
btw–I have a MK1 with just the APS transformers and it always sounds mellifluous.
It could be the power supply. I don’t know.
The sound is just glorious. It seems to be good for a day or two.
I have a DSD MkI with the APS version 1 transformer along with the upgraded caps. I leave it powered up all the time and the sound does not change.
I don’t know why my DSD mk1 APS modded with external Keces P3 power supply goes off after a day or two but it does. So far I am on hour 24 without issue. The sound quality is spectacular.
Apparently after much research I have discovered that my dac is not broken. It’s the nature of the FPGA module to need reset after time. The APS mods show the sensitivity of the dac more and the external power supply shows the sensitivity even more which is why Jeff(JKRichards) from APS Audio Transformers no longer offer the external power supply option due to people having the same issue I have and my research shows me that a reboot after a couple of days for optimal sound is not that unusual. Many turn their dacs off when not listening which reboots before every listen ing session.
Apparently further modification of the internal power supply of the dac lessens the “drift” problems but the modification is several thousand dollars and too expensive for many who just option to purchase a new dac.
unless designed to turn off after preset time period electronics should not turn off. I spent decades as an electronics technician. This is a failure, most likely related to temperature.
