LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING

I am replacing the Plinius Koru phono stage this week with a BAT VK P12. If a 8000 dollar tube phono stage can't make this cartridge sound good then it's not my 12k dollar Krell amp, it's not my 5k dollar Ayre preamp or the 5k in cabling. The Delos with be replaced.  I'm having a VPI guru come over and check the calibration of my Classic one turntable with the Delos. adjusting azimuth and tracking force does not change the sound of the cartidge.  It only affects imaging. The Delos sounded fantastic when I listened to it on all very expensive McIntosh tube gear. Maybe throwing some tubes on it will give me the sound I'm looking for.

Even small changes in tracking force should alter the sound of the Delos quite a bit, which suggests that your current setup has not managed to extract all of the performance that the Delos has to offer.

Nonetheless, I wish you the best of luck with whatever you replace it with.

kind regards, jonathan carr

Jeff, Tube phono stages per se do not "roll off" highs.  Perhaps a tube phono stage may have an audio bandwidth out to 100kHz.  Whereas a solid state equivalent might go out even farther, but you are not going to hear that particular difference.  You'd be more likely to hear a difference in bass definition, but such generalities are dangerous if taken as gospel.

What the OP is describing sounds more like a poor setup.  Tracking force too light, VTA way off, arm mass way too light.  

Nothing can fix a poor setup except improving to a good setup.  That's why there are turntable setup specialists.  

Jeff - do you understand jcarr IS Lyra ?…
