I used a Shunyata Venom on my B60, and since moved up to a Shunyata Diamondback (the Venom is now on my DAC).
In a nutshell, the B60 sounds like it breathes better with the Shunyatas. Music seems to flow easier, and it sounds more relaxed and unforced. It initially sounded a bit softer, but after getting used to what it was doing, that wasn't the case. It's also a bit cleaner sounding, and it removed what little bit of edge the highs had.
Both have had the same impact and changes to the sound. The Diamondback took the improvements to the next level.
Not sure what amp you're running, and if either power cord will work in your system or not. If I wasn't so familiar with my gear when I first added them, I'm not sure I'd have picked up on the changes as easily. I've found that with a lot of cables. You need to live with the gear for a while, and small changes to most will become far more obvious to the owner.
The Venom was $99, and the Diamondback was $125 when I bought them. The Venom has been replaced with the Venom II for about the same price, and the I see the Diamondback at Music Direct for $100 or so.
My room, my system, my music, my ears... No guarantees as to what anyone else will hear.
