I don't know. I'm not there. Mana is great stuff, but harmonics and tune are secondary to overall detail, and a very etched focus to my ears with Mana.
However, JW's own system did everything right except Nitin Sawney's plunging bassline on track 6 of the Broken skin album, and to be honest, if that was the only fault of the Briks he's got, I'd still buy a pair for everything else they did right once I get moved into a house with a bigger listening room than the one I have right now.
Me want Briks!
