As a newbie to XXHighEnd (but with over 30 years of highend audio experience) I find myself both bemused and confused. First off, I love the sound. When I first set it up and heard it from the corner where my computer is, back to speakers and way out of the sweet spot, I was startled at how "right" this sounded. Recently I did some AB comparisons with my CD player (Stereophile A+) and could detect no differences, yet when I just sit down and listen to XXHighEnd I am hesitant to end the listening session, because the musical enjoyment is so high. What is happening here? By the way, I am listening on a Sony VAIO laptop, which is connected to the Internet all the time, using Vista Ultimate and a Scott Nixon NOS USB DAC, through Bottlehead 2A3 Paramounts (currently passive - preamp off for repair) and modified Bottlehead Straight 8 speakers Now I am thinking of selling the CD player and getting a dedicated computer.
Welcome to the "club", glynnw. XX is simply better than anything else. If you tweak you media-PC a little bit (e.i. avoiding USB interface) then you will get a sound closer to the mastertapes than any CD-player at any price. That is my experience and opinion.
PC-audio is still like shooting on a moving target. Not all the stones have been turned yet. You will find lots of tips and hints here on the forum.
