Just received the same builders version of the f7, very happy with sound and build quality. Definitely sounds class A with super pure and natural vocals like a veil was removed between the singer and the mic recording them
hi Nicholas, just wanted to say your great 6moons review is one of the main things that helped me decide to get my kismet in khartago case monoblocks as my end-game final amps for my main system. The amps are everything I'd hoped. I'm also in hawaii :) Hope you're doing well.
