I have owned a pair of Heil noise-cancelling headphones for many years. They worked very well to reduce the noise of my old AL-1200 amplifier, and the 5 fans on my cantankerous man-killer Henry 2002A EME amplifier. However, they are completely ineffective against the KPA1500. I bought a pair of Bose noise-cancelling headphones recently, and they work much better but are a bit tinny and eat batteries. My question for the audio experts on this list is why don't the Heils work with the KPA1500? Does anyone have a recommendation for a pair of really good noise-cancelling headphones with a more flat response? 73 Eric WD6DBM
