Rowland Amps with MBL Speakers vs. All MBL System

My reference is the Jeff Rowland Synergy IIi Pre & Model 302 Power Amp.

I recently heard MBL's omni-directional speakers for the 1st time, and was absolutely blown away by their amazing life-like performance. They were in an all MBL system.

Regarding this, I am looking for input from folks who are familiar with both of these lines, or have done some head to head comparrisons of Rowland vs. MBL electronics.

1) In general, how would you decribe the sonic differences between these Rowland components in comparrison to MBL's "Noble" pre and power amps?

2) Do the MBL speakers need to be in an all MBL system to do their magic, or could the MBL speakers be a good match with my Rowland gear?

Any feedback from personal experience would be appreciated.

Thanks
