Tango Step Up Transformers vs Bob's Sky Blue Cinemag

Well, All I know is that my biz partner, Taras,...while at a show dinner, sat near Bob and some industry leaders and the conversation turned to a discussion on transformers. Bob acquitted himself well (gave better than he took), and is no fool when it comes to transformers.

Both Tango and Cinemag are excellent! Tango.is certainly the best audio.transformer company in Japan. My Sanei SET 2A3 has all Tango iron, including chokes and power transformer. I would characterize the sonic "flavor" of the Tango.and Cinemag SUTs as that of two different maple syrups from different areas! 

Haven’t heard Tango, but the blue-label CineMag / Bob’s Devices Sky lineup is excellent. They’re on the warm / lush / fleshy (even slightly "bloomy") side of the tonal spectrum, but they’ll still be more detailed than lesser (cheaper) transformers like the CineMag red-label 3440A, Lundahl’s lower-end LL9206, etc. Pairs wonderfully with everything I’ve thrown at it -- Ortofon Cadenza Bronze, Koetsus of all stones & cantilevers, top Shelters, etc. Or course the Benz LPS doesn’t mate well to SUTs in general, but that’s not the Sky’s fault.

The Sky has a pleasing, musical sound that’s fun to listen to. It doesn’t have the laser-beam razor sharpness of some others (Lundahl LL1931 and LL1931Ag), but for me that can get in the way of music too. Adding a Sky in place of a SS headamp or MC stage can often alleviate problems with "anemic" sonic balance, yielding newfound weight and palpability to the music.

Thank you everyone for your responses so far.  It sounds like I can't really go wrong with either.  Your help and comments are greatly appreciated!

Best Wishes to all,
Don
