I was listening to some santana today and suddenly the volume went down by maybe half and sounded kind of muffled. I turned the volume up a click and it sounded a little louder but still muffled.
I changed out my tubelab SSE amp with a class d amp and it still sounded off.
I then thought it must be the dac output tube. I opened up the dac and swapped in a new ge white 5 star. It still sounded wrong. I swapped the amp to the non tube output jacks and it still did not sound right.
I replaced the DAC-09 with a Berseford dac and sound was as it should be. I put the tubelab sse back in the chain and the sound was still good.
It must be an issue with the DAC-09. Any suggestions as to what to check next?
