Hot Deal Update:
Since was in the vicinity of Boomerang @ VT, Mumbai day before yesterday, decided to go & check out the combination.
The Monitor Audio M4's were paired to the Marantz PM6003 with a Cyrus CDp used as source, since they did not have the Pioneer DV220 in stock.
First impressions of the set up were really good, pairing of the Speakers & amp is great,
liked what I heard, though this being an unplanned visit, had not carried any of my music along. Plan to carry my music & audition again soon.
The M4's look really tiny for Floor Standers, at first sight I nearly laughed looking at them! But their sound is very good & so is the delivery of bass quality. Instrument Separation is great & so is the vocal delivery. Heard Dire Straits, Allan Taylor & Some Jazz Cd's. All sounded really nice & mellow. Wonder how they will handle some Hard Rock & Metal

The M4's are front & rear ported, front port for the Bass Driver & rear for the Mid Driver, as was informed by the sales rep.
Was also informed that the M Series of Speakers are a new line of Monitor Audio recently launched, with pricing that seems to be on the VFM side. The M4's are quoted @ 27 k for a pair.
