With easy-to-drive headphones / iems does it make sense to turn it into high gain? Does it improve the SQ in any way?You can use a 3.5 to 3.5 mm adapter, it will "trick" the tempotec sonata HD Pro into going into the maximum 2 V output all the time.
I've bought 2 tempotec sonata HD Pros, one is 9 months old, I use them daily and no issues. But I am very careful with them, the wires are a bit thin, so I try not to snag them on anything and put them in hard cases when not in use.
Also if I want can I also connect an amp to Tempotec Sonata HD Pro and use it only as a DAC?
