sonic comments: -------------- "Changing the original 6021W in my Audio Aero Capitol Signature to Platinum Sylvania 6021W was a big improvement. The audio aero is more musical, better details, the sound stage is deeper, more holographic, better dynamic too. For me, the audio aero is now better in all." Bests regards, Dominique/France
