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 ...

@tommypenngotti, If you have sound in both channels nothing is shorting. Lyra absolutely does not like that arm. They specifically specify "a pivoted arm with rigid bearings or linear tracking arm." That does not include a unipivot for very good reason. They are unstable. You are having more trouble with the Lyra which is a more compliant and more sensitive device than the Hana. It is a great choice just not for that arm and I do not know everybody else's motives, but I do not have one. There are certain aspects to tonearm design that can not be violated. There are plenty of people in the audio business that are not rocket scientists and many have motives that are probably not in sync with yours. Yes! the Fatboy Gimbal is way better. Go for it! |

New theory : the Lyra cart doesn’t like my phonostage . Allnic 1202 ohms aren’t jiving and it’s making the Delos work too hard and I get low end rumble at higher volume . The Allnic does have variable gain boost ..I’ve tried them all and same result . I seriously doubt it’s the position of turntable or the arm because pretty much same arm on same deck with lower gain Hana ML cart works fine .
