After 3 days of music in my not so big 35 m2 room, I can only confirm what I wrote above.
1) this is by far the best speaker I heard, incredible fast, involving and delicate.
Resolution is definitively better then various electrostat's I had, this speaker is terrific!
And I have to add this: alltought the cr1 is one of the best speaker, the r1 is...
a further step above, the soudstage bigger and more detailed, a more life size imagine, more "air" in the room..
The set up was very easy and fast, no boom or strange room interactions..
And the R1 has obviousely a light load for amps, and quite efficient.
2) as i reported, the combination with viva audio pre and viva audio aurora 845 is... incredible.
Seemless, delicate and thounderous, with holographic portrayal. Perfect for highres files of ecm,
Reference recording etc, but also for j. cash, lou reed, radiohead, glenn gould, keith jarret...
In one word: breathtaking.. Only the magico q7 impressed me equaly.
In my opinion way more involving than big tad amps, big soulutions ecc.
Cabling is mit ma-x for signal and (biwiring) kondo spz for the speakers.
I am incredible exited and happy with this combo!!!!
Best wishes to all Tad - lovers!
