The Cayin brand is owned and manufactured entirely by the Chinese government.  Personally, this would be a deal breaker for me though I know for others it is not an issue.(Yes, I know where my iPhone is manufactured, thank you.)
No. I like manual anyway it feels like i have the control. By the way Tekton perfect set 15s came a couple of days ago. I am really happy with the great match. 
Thanks cb3489. I am very close to getting the X9 to drive my CW IV. How is the X9 bass control compares to your X7? Roll any tube yet?
No power tube rolling. It has been confirmed that they muzishare branded psvanes 300b. Changed preamps with tungsols. Made huge difference. Bass is very different than x7. If you are in los angeles area you can come and listen:)
