Things go from bad to worse. Following my recent disappointment with the Cambridge DAC Magic I am now at my wits end with the whole 'up-grading' quest. On Tuesday of this week I took delivery of an Audiolab 8000Q pre amp and two Audiolab 8000M monoblocks. I spent an enjoyable few hours unpacking, re-routing cables and setting up the new amps. I fully expected a harsh sound from new and that is precisely what I got through my Mission 753 freedoms. Anyway, they seemed quite punchy, compared to my old Sony, so I made a note to wait until they'd had a good run and then start getting serious about room EQ if they hadn't mellowed. By Wednesday evening I had to throw a folded towell over the tweeters because the treble really was ear-piercing, shrill and horrible. I'm not blaming the amps for this. I know my room acts like a bass trap and I need to try to sort this. So far then, not having much luck. Money spent, sound is 100 times worse now than ever before. But here's the rub: I get up this moring, switch everything on ... except that one of the monoblocks doesn't come on - at all. Checked fuses, swapped power chords etc, etc - nope - nothing - it is dead - already! 2 days! 2 poxy days it has lasted. I mean it's not as though there's much to go wrong is it? There's only an on/off switch and they can't even make that last more than 2 days! I'm totally hacked off with this rubbish. So, merry Christmas to all at Superfi and Audiolab - with a special mention for quality control at Audiolab. Well done people!
