I dont live near an audio shop with the kit I am after and therefore cannot arrange a demo easily. If I do it will be at some effort to myself and the retailer and I will end up getting the kit of the net anyway. Id rather not waste either party's time. So at the risk of saying the hifi equivelent of "Does God exist", Is there a discernable difference "TO AN AVERAGE CONSUMER" between Amps of the same build/cost/brand levels? I am in a Yam (630) vs Marantz (5200) dilemma. On the web in specs alone the Yam has all the bells and whistles but the Marantz seems to get the rave reviews, (Especially where using the Amp for stereo source material is concerned). Will the audio differences be detectable to me an average consumer or are the differences for the audiophile perfectionist? Im appealing to those who have a similar dilemma. Will it be purely down to personal taste and therefore either choice is valid and the difference marginal or will I be buying one at the risk of hearing the other and being mightily upset? I will be using it with Mission 77C, 77DS aand 773e setup and Sony 735 DVD.
