Hi Edjis,
I listened to the samples and the JZ 301 have a tighter bass response and much more detailed transients response... it's a great mic! I like it better than the akg..(in comparison the akg sounds muddy...)
The boxes are very cool, as always JZ hits with some serious stuff.
I think it's a great company (as many other out there) because have some great products with innovation (specially but not only in the design) at a fair price.
I've always been a JZ/Violet fan...
just my 0.02$ (i don't work for JZ/Violet and I'm not affiliated with them in any way.... unfortunately..)
Greetings to Juris and to you all!
Ciao!
