No deep bass or highs: VTF or VTA issue?


Background:

I've been using JM Lab Micro Utopia monitors and recently added a sub (via Bryston outboard crossover). Used my music server to dial in the sub (for convenience) and after dialing it in I noticed that my analog rig is not sounding anywhere as good as my digital.

I tried comparing a few LPs to their digital counterparts and in comparison the LPs sounded dark and sluggish.

Relevant equipment:

Analog:
- Dynavector XV-1s
- Scoutmaster / JMW 9 Signature / SDS / Super platter etc
- Aesthetix Rhea Signature with NOS tubes

Digital:
Music server -> Benchmark DAC

I used a Mint tractor to align the cartridge, and the VTF on the XV-1s is around 2.0g. I had never done anything about VTA, so I tried raising it. It got somewhat brighter, but now in comparison it lacks deep bass AND the highs of the digital version. Switching back and forth it's like the vinyl is just midrange (that's an exaggeration to illustrate my point).

I also have a Manley Steelhead phono stage; I should probably swap that with the Rhea to make sure the phono stage isn't the culprit but my gut tells me that it's the setup.

Any advice on what adjustments to try would be much appreciated.

Thanks.

Quick question: when you adjust VTA, can it affect overhang? My brain keeps telling me that raising VTA would pull back the stylus...?
Dear Madfloyd: How " things " goes before you add the sub? the analog quality performance was better than the digital one?
Btw, check that the tonarm wires are connected to the XV-1 pins in the right way.

Regards and enjoy the music.

I never really directly compared digital to analog prior to adding the sub.

I'm now wondering if my problem was simply VTA was off and by changing it I've messed up overhang.
Ian -- My understanding is that the Mint Tractor is customized based on the exact pivot-to-spindle distance of the particular arm. Are you certain that the mounting hole for the arm is drilled in exactly the right place on the armboard, and that the pivot-to-spindle distance that the Mint was customized to corresponds to the actual distance?

Also, I would expect that the effects of geometry-related problems would vary depending on what part of the record is being played. Do you notice any such variation, or are the character and magnitude of the symptoms consistent throughout the record?
