The review by Douglas Brown of the Furutech included these two statements:
"the increase in sound quality was so immediate and dramatic"
"the improvement in sonics was so clear that I could literally hear it in other parts of my home"
I generally think that the believability of a review is, in part, indicated by writing the opposite words which therefore describe the extant system, and then deciding if it is an accurate description, namely:
"the inferiority in sound quality was so immediate and dramatic"
"the inferiority in sonics was so clear that I could literally hear it in other parts of my home"
For me, these types of hyped-up reviews encourage me to have no interest in the product - and I would guess that the manufacturer might prefer something more tempered to provoke interest rather than something extreme which, for me, does just the opposite.
