SHAMEFUL is correct. I chose this as my first real ..'investment in serious Chi-Fi', to the tune of 300 NZD plus, wrestled on some Final E Series tips, selected a favourite tune where the bass gtr is a leading protagonist (Jolie Holland's 'The Littlest Birds") and upped volume, whereupon the bass promptly TURNED TO ABSOLUTE CUSTARD. I'm talking complete disintegration. Truly I cannot believe it. Three hundred clams down the gurgler. I am gutted.
