Seriously, I would like to see the KPA1500 available with a larger finned heat sink and in a larger enclosure using 120 mm fans. That would move a lot of air across a larger heat dissipation area keeping noise and temps down. I love the 1500 and under normal use I can tolerate the noise. Contesting gets a little loud. That is what the Bose QC30 noise cancelling headphones are for.
