Hallo Gizzy.
I see that you are a fan of Yamaha NS 690. I have MK III version and a problem with amp. Please help me to find the best solution for my Yamaha. Now, I have Pioneer A9 (1981) and problem with mid tones. Especially with piano, and with vocals. It s sounds very high and crispy. To bright for my taste. I want to fix that with better amp, or with cables, because i love the look of 690.
Best regards!
Bonaca!
