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 ...
I haven't heard YOUR table / arm combo with a Delos. But I have not had good experience with Lyra cartridges with the VPI 12" unipivot arm (VPI Aries Extended). Have not heard ANY Lyra cartridge work well with a VPI unipivot arm on any table. I switched to a Jelco TK-850L and both the Lyra carts I currently have just love it. I have heard VPI unipivot arms work VERY WELL with AudioTechnica MC carts. |
My direct experience was with a Lyra Clavis Da Capo and a Skala. Both were defocused and thin sounding on the VPI JMW 12 on an Aries Extended (original). On a "custom built" table using original VPI TNT components and a Jelco TK-850L, both opened up, had great tonal body and remarkable imaging and soundstage. Maybe the VPI / Lyra recommendation is associated with the gimbaled arms.

@tommypenngotti Since this is volume related it leads me to think the turntable isn't well isolated from room/air -borne vibration. If it were me I'd be looking at things to improve its isolation- better feet, an anti-vibration platform, that sort of thing. |
