I am experiencing a strange problem with playing LPs on my very basic Dual 510 TT, fitted with original(!) Shure M95 GLM cart and a new stylus. In the treble, I am hearing the following nasties. [LIST] [*]distortion, for example quavering of voices that is particularly noticeable on female vocals [*]enhanced sibilance [*]crackle not attributable to surface noise [/LIST] In the rest of the range, I hear the following [LIST=1] [*]listless dynamics, [*]slow sound (almost like it is running under speed) [*]shrunken soundstage [*]veiled sound. [/LIST] I have run the HFN test record and nothing obvious shows up, it is even tracking the anti skate tests quite well for such a basic deck. I have checked the deck is level, cartridge alignment was roughly OK when I checked it a few weeks ago. I even swapped in a spare brand new stylus which made no difference. The Dual TT is running into the (eerily quiet) phono stage on my normally reliable student days Yamaha AX300 amp that I have been using in absence of a phono stage. The din output of the TT is run thru an old DIN-2 RCA converter that was probably supplied with the TT. Unless my ears are deceiving me, the problem seemed to happen almost instantly. I was quite happily thinking how good everything sounded when playing some rock. When I spun a few LPs later the same day, the problem just leaped out at me. I played the same LP I had enjoyed earlier and it just did not sound the same. Any advice, help or tips on diagnosing the problem (assuming it is not my head!) would be most appreciated. Many thanks,
