Anyone Using Harbeths with Grilles off?


Curious whether anyone prefers their Harbeths this way. I would imagine it's room dependent-- they are obviously voiced with grilles on but if your room is unusual (like mine is) maybe they sound better this way. The highs are getting eaten up by furniture and old ears and a strange loft type room at my place so it's working here.

I had a pair of Super HL5 Plus, I didn't notice a difference with the grills on/off. 

Also, the easiest way to get the grills off is with a cheap magnet from Home Depot, doesn't leave a mark. 
I know Harbeth recommends grilles on etc.  To me,  in my room, the M30.1s image better with the grilles off.  
With the 30.2 there is boosted bass if you remove the grille. Though I highly reccomend removing the grilles on the 30.2, if only to remove the magnet behind the logo that rattles against the cabinet enclosure very loudly during strong bass.
Harbeth also recommends just about any amp over 50 watts. I'm sorry...that's not flying with me. Just saying (-: Back on subject...I enjoy my P3's with Grills on, and don't want to mess with them. Cheers -Don
Grilles off for me. Besides the asthetics and badass Anniversary logo, it gives the 40.2a 0.5db boost from the tweeter which I need. Zero impact on bass driver.
