I was a way on anniversary celebration and came back now.
Firstly: The JH13Pro is unrivalled for sound - who knows, there may be another which sounds as good, but I have not heard it. The details (not high frequency, details in any frequency) are unfathomably good (yes, I made that word up).
Secondly: I tend to rate SQ above all else, however it is balanced with other aspects and taking into account that not everyone likes the same sound, I won't blabber on about what sounds good to me. If it is obviously good, it is good. If it has big problems, those will be taken into account. The JH13Pro has no problems with sound.
Thirdly: Build is very important for me. For more than 1000$, it had better be amazing. Irregularities (those happen) and aren't a big problem, but things like bent pins (mine are slightly bent after doing nothing but carefully take the cables out for pictures) are off-putting. The cables themselves, as opposed to some high quality manufacturers (not all), are the same as some universals, not a special, high-quality version.
I think it is obvious that JHA developed a world-class product, but it isn't perfect, at least to me. Had it sounded rubbish, but had a great cable, it would not be ranked as highly, but when I review products, I review them in my way which should be obvious: cables are important. There are many products which would get a 5/5 had they had a better cable. But, lacking that, and a high quality connection which will last and protect the cable is very important to me... and counting from the numbers of cable returns (from the company who use the same cable), this may become a problem with the JH series.
Do I love them? Yes. Do I think they are worth 1100$ - if all you care about is sound, then a resounding yes. But as you can see at TMA, my reviews focus on a bit more.
