LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING

something is drastically wrong.  the Delos is an exceptional sounding cartridge and is not at all bright or shrill.

if you tried loading at 200 ohms, make sure the VTF is dead on 1.75 grams and your headshell is perfectly level to the platter when the cartridge is in the groove, something is wrong with the cartridge or installation.  
have you checked the phase of the lead wires?  

Given the OP's stance, there is no point in further discussion or advice about the Lyra Delos. He clearly had made up his mind about the cartridge before his OP and simply wanted re-enforcement for his position. I am off this thread now.

A Puffin could make it sound good.

Find better recorded/mastered LPs! Particularly original ones from the pre-digital era (1980). Avoid new reissues that were digitally mastered!
