how can a line cord affect frequency response ?

i think it's ok for audio professionals to have their say as long as they do not attempt to sell on a discussion forum .

does anyone think its ok for a manufacturer to market his/her products on a discussion forum of this type ?

Holy cow!

Common sense abounding Tvad, what is Audiogon coming to?

i agree in principle, but if it quacks like a duck, looks like a duck.... it's a duck.

if someoneone wants to spin what is obviously selling into some other activity, we'll have to agree to disagree. like everything else in life, perceptions differ. you may see day when i see night.
