So the
Oriolus BA300S tube amp for the 1Z is in the house and under testing with the Solaris.
I'll add this in the review when I have had enough time with it but after an hour with it I can say the Solaris scale well and, the very interesting point is that it takes the Solaris a few notches up on the bass... what I did miss with the 1Z alone I don't anymore with the BA300S, the mid bass kick I was missing is here and the best part is that it's without loosing anything in terms of textures and layering quite the contrary
I think this small tube amp would pair so very well with the ZX300 as it's the same form factor, making it a potential killer combo for the price.
On monday, I'll get the 8 wire Hansound Zen and then I am set!
