Dear slowikpl,
Many thanks for those informations. Mine have nox 60h and so far of break in. In his time i compared xa60.5 and xa100.5, and there was a big difference as the 100.5 had much more bass but high of 60.5 was more beatiful. The gap between 160.5 and 100.5, is great and treble is more detailed, bass is deeper , tempo is faster so we have more slam. But i am waiting till they will be broken to go further in description.
At least 300h....
Now, it's normal there are big differences with 60.8, look what is inside both amps and you will find the answer.
