It's been a while since I've posted something here. I've got my TA-N7 restored and the results are quite interesting.
I'm going to compare the Sony with my two B-3s in BTL. Of course, it may be just my lying ears but it's something like this:
1. Sony resolves more detail
2. Sony's got a bit more air
Otherwise they are rather similar in every way.
When I pitted the B-3s against the Accuphase A-75, the B-3s were clearly better and I reckoned that the B-3 is a pinnacle of sound design. However, the TA-N7 just proved that it can always get better.
