Do not worry about the grade. It must be as familiar in order to be able to write a review. I do not give a rating but hope to be helpful to people with similar upgrade thoughts I had.
I have a Yamaha RX-V3900 surround amplifier that cost 17000kr 2009. It plays in front 2st ELAC FS 207A (13000kr in 2009). My idea was to economically spruce up the system. I was particularly looking for more punch and control in the base after hearing the speakers play more authoritatively on a TEAC HiFi amplifier at a trade show. I heard me with a renowned HiFi shop recommended Roksan Kandy K2.
Immediately heard no difference to Yamahan and after playing through a bunch of favorite songs, I think the options are very similar. Both play with good resolution, warmth, heart and powerful bass with right good bounce but a little too little control (ie cloudiness in the deeper range) with my ELAC.
One can interpret it in different ways. Kandyn play as good as twice as expensive machine. On the other hand, plays surroundrecievern which of course works for both audio and video and can control up to 11 speakers, an integrated amplifier, has a DAC converter, at least as good as a reputable stereo amplifiers for almost 10000kr.
People with a different set, such as a cheaper surroundreciever, can reasonably get a good lift with Kandy K2. But I return the mine and upgrade the speakers instead.
