??????? So, your friend and dealer Ed knows everything about AC power and audio? No, he cannot. No one (including me) knows diddlysquat. There is no actual objective measure in audio. And EVERYTHING you do changes the sound. We are all very ignorant of the possibilities.
What if Fremer used a couple of Giandel systems and Puritan filters....could be way, way better than what Ed did for him. KNOW ONE KNOWS......we are in the dark....however, you can try things and find out for yourself.....or just pay your dealer big bucks because "he is an expert". Maybe it will sound better.....and if you can afford what you spent and like the results....that is all that matters. However, you really have no idea of what other possibilities there are (and for fractions less money) unless you actuall try other things in your system.
Did you read my post? Have you A/Bed a $27K Stromtank that holds 2100 watts with a $2K Giandel system that does 5000 watts? What do you know from direct experience? Has Ed bought and listened to the Giandel system? (of course not....he cannot make any money off it).
Someone can buy the Giandel and batteries and charger ($2K) with money back guarantee and borrow a Stromtank from a dealer and listen for your self. But, You say that is too much work....you are a lazy type....you would rather give thousands to the dealer because he needs to make payments on his new Maserati.
What do you want? To spend money?.....to buy cool stuff?....to have the best sound?....even if it means spending less? Do you want to be happy? Then choose it now.....right this moment......it is your next breath. Audio is just a game......not even in the same league as love and joy and fun and creativity and peace.....which is all available right now. Of course, you can do audio while you are in love.....I recommend it. Do everything while making love. For there really is nothing but God making love to itself.....forever. Can you dig it?
