Recently purchased a Chiro 200 on eBay and am thrilled. Moved out my B&O S75 speakers from the stereo system to the theater room and brought my B&W Matrix 801 S2's to the 2 channel room. Pulled out my B&K ST202 plus and started pulling out the vinyl. Wow, the sound stage got not only deeper and wider but therer was height! Even with 140 WPC to the B&K's 200, the bass was tighter and more defined. The B&K had a tube like sound that didn't mate as well with the 801's, they opened up with the Chiro. Transients are better on this amp also. I felt as if I was listening to music, not electronics. I am going to sell the B&K along with a Hafler DH200 and settle in for a long life with this amp.
