I had the opportunity to audition the Nu Force 8a's. They werent to my liking. I appreciated the opportuinty, but for my tastes I did not like the sound.
That being said, this is one of the most interesting audio tests I have seen in a long time. If I decide to purchase a digital and have to pay a premium, I want to know that I am getting great sound.
I'm still waiting for the cheap, killer digital amp like everyone else but if manufacturers can best realisitic and solid SS choices (read: non boutique) at the same or lower pricepoint, I'll jump on board.
