Throughout the years, it has suited my needs admirably. 'til now. I am getting increasing hum and hiss in both channels, and I assume it's due to aging of important components and/or solder joints. I would ideally like to replace the Hafler with a better unit, but at this point my budget (and wife ;-) won't allow it. I've heard of good modification kits for the DH100, and would like to hear from those who have experience, good or bad, with any of them. Your help is greatly appreciated. Thanks, Pete peteg@sequent.sequent.com ..{uunet,ogicse,tektronix}!sequent!peteg
