Nikolay,
I'm using a pair of VR-6 speakers and am amazed at how great they can sound. Like so many of Albert's designs, they benefit from the best upstream components, down to the speaker cables, interconnects, and power cords. Readers will not be surprised that I recommend you try the MasterBuilt cables, even the Standard series (contact VSA for info). Though the VR-6 speakers will illuminate any weaknesses in your components, they also have the potential to be the foundation of a really amazing system. You've got a gem of speaker system, enjoy!
