I dit listen to the 8k - not heard 7k.
The 8k dit "sound" sooo good,that i have finally to buy it.
I like the "sound" of the 8k,
because they have no "sound".
That means the music get produced as recorded.The speakers dont add or subtract or distort anything from the source.
Maybe thats one reason,why DSP speakers dont
"sound impressive" for the first impression.
But after listening a while,you get really impressed about the great performance.
Connected with the 861+800,for me its best reproduction i ever heard.
With an analog chains,i never heard that quality.
