Tommy, you have several problems that lead to issues like this. Your turntable is not adequately isolated and Lyra cartridges do not like unipivot arms. You need an isolation platform tuned to 3 Hz or below and a gimbal pivoted arm, then the Delos will work fine. Lyra cartridges are relatively compliant and that arm is also too heavy for it.
VPI Prime Sig/Lyra Delos / Feedback ...help!
Hello all, strange one here...just picked up a VPI Prime Signature Rosewood and a Lyra Delos with about 20-40 hours on it...sounded great at low volume with my sacred Steely Dan - Aja Cisco pressing . Later that night at higher volumes I'm getting a midrange-low feedback .
Here's my rig :
VPI Prime Sig with Unipvot / Lyra Delos 0.6m output voltage / 1.75 tracking force
Allnic 1202 Phono Pre (variable DB boost +22, +24 , +28, +32)
Manley Snappers / Jumbo Shrimp Pre
Harbeth 40.3XD
So I A/B'd w the old turntable VPI Prime Scout / Unipivot / Hana ML 0.4 Output and all was fine 🤔 I then swapped arms moving the Hana to the Prime Sig , no feedback ....🤔
I've tried adjusting the Allnic (all 4 levels mentioned above) and get feedback with the Lyra on every setting...
The hifi business I purchased from said they had tested thoroughly and had 0 problem with it ...so I'm perplexed , this doesn't seem to be any vibration feedback , is the Lyra just not jiving with my Phonostage for some reason?
Any help appreciated ...
