LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING

I think moving coils are overrated.

I think we have found the crux of the issue here in terms of the sound the OP prefers.  It's all a matter of preference and what sounds good but I suspect his tastes lean towards less resolving and a hint of warm distortion in his signal.

Can we keep the old, boring, and endless MC vs MM/MI debate out of this thread, 3 easy?There does seem to be a consensus already that the OP’s experience with the Delos cartridge is very atypical and that he might want to consider having the cartridge inspected for defects. Now he was invited to do that by the guy that makes the cartridge. You can’t do better than that as an endpoint.

My apologies for taking the bait @lewm when the OP stated MC's are overrated.  I should I have taken the high road.

MC's are COMPLETELY overrated.  

"When I heard a Demo of the Delos it was on an all tube system. Mine is solid state. There is the problem. I would not recommend this cartridge to anyone unless you have tubes which roll of highs and add body and warmth to the sound. "

Perhaps your tonearm is not damped enough.  It takes a while to dial it in.  Try a lower tracking force.
