Hi Jack
You'll need D5K2's minimum I'm afraid smile

The M6's are a BIG step back from what you currently have and indeed, much of the Meridian DSP Range

You could try the new D3300, but once you factor in a required Stand, the Space taken up doesn't become any smaller

The 818 sounds great, but you'd notice good components and speakers downstream to notice a difference compared to the already good MS600

You have that now obviously........but the M6 and other equipment choices would negate the advantage of the 818
