I am maybe a little bit late here but something very important to point out with Sarastro is to use them with bi-wired (2 speaker cable runs are even much better).
If they are connected this way, you will have the most natural, musical and coherent speakers with correct timing, an outstanding resolution, great soundstage with depth, width, great focus and solidity, bandwidth, low level detail, dynamics, transients, accurate tone & timbre, etc.
I fully agree that they are not as coherent, with differences in timing and between the 2 modules and sometimes tending to be hyper-detaile,. when connected mono-wired and with their own jumpers,
I have not a technical explanation, since am just an audiophile but this is what I have experienced. I was tired of moving them around my room, trying to find a good spot/placement (tilt, toe-in, distance between tweeters, to walls, etc) with a better integration of tweter and between the 2 modules and was just about to sell them until I bi-wired them with Dream Stealth Speaker Cables instead of mono-wired with same cables. A connoisseur friend, distributor of Audio Research, Kimber and ProAc in Mexico gave me the hint. He mentioned that this sometimes happens with many speakers that were truly designed for bi-wire as ProAc.
Hope this helps with current owner's of Sarastro.
I also agree with comments about Saratro I is better than Sarastro II. I had the chance to audition them side by side and believe that the tweeter on Sarastro I is more natural and extended with less glare. I also believe that the crossover (different form I to II) makes a better job when bi-wired.
