I'd have to agree with you with regards the Shure. I'm way behind when it comes to assessment due to having an absolute sod of a time trying to suss out a ground loop hum. I'm still working on it but I have to say that my configuration of the SC35C would need a cart costing north of £1K to beat it. I just need a break with this ground loop hum to get the best out of it.
