* Fascination Kenwood KA-907!
+
== Berichte ==
−
* An amp. with unadulterated sound, absolute noise-free, stereo channel separation, the minimum distortion up to the highest volumes, no matter what speakers. The 907 shows how good speakers are. If the sound is bad, it is because of the speakers! An amp should reproduce signals without distortion, preferably with a lot of power, and the 907 does that brilliantly! The quality is unique! Especially for phono lovers! Developed by Trio-Kenwood!
