I haven't and I am happy with what I hear. But of course, it could always be better... I use a common mode choke on the primary side of the power transformer as a rule. For "big" power amps (25w + 25w) that means a 3.3mH 4A Panasonic job. I recently discovered that you can get these for pennies (well, about a dollar) from www.bgmicro.com (cat # PWR1025 or PWR1026).
