Trelja, the only point that I have contention with is the use of lin conditioners. You must take into consideration how well your A/C is regulated by your power company. I am a professional CET and as part of my daily grind, I repair units that have been damaged by insufficient regulation. If your line voltage is to be regulated at 117 VAC, any variance, up or down will degrade the performance of any electrical appliance. It dosen't matter if the appliance is a toaster or a pre-amp. Case in point, my own a/c varies by day, time of day and temperature. Between the hours of 9:00am and 5:00pm the A/C is pretty consistent, but around 5:30, A/C line voltage will drop by as much as 15%. The line conditioners will help combate these irregularities and prolong the life span of your equipment. You might want to reconsider these units, if not for the sonic values, strictly for the power oriented. I'll save my picks on good equipment for another thread. Enjoy!
