[TenTec] Centaur cooling mod for lower noise?

[Gary Tuck]

Another "solution" if you wear headphones is to try a set of noise  
canceling ones.  I've not tried the Heil cans, but have used the  
Noisebuster FX and Solitude as well as a Sennheiser HD 280 passive  
set.  The former at $69 work the best with the Centaur and are very  
comfortable. My daughter, a musician, now has my HD 280's and I wear  
the Solitudes when I'm cutting the grass!!  That's not to say that  
the more expensive Solitudes and Sennheisers wouldn't work best at  
what they seem designed for, airplane travel.

I also bent the intake louvers to the horizontal plane which seemed  
to reduce the "howl."   So, I wear the Noisebusters all the time and  
when I crank up the Centaur, I just flip a switch on the headphones.
