Ugraditus is calling....again. Phono stage?

There is likely nothing wrong at all with present phono stage but you know how it is.

Present analog front end consists of.

Nottingham Analog Spacedeck with Spacearm.
Shelter 501 mk3 cartridge with maybe 250 hours on it, regularly treated with Lyra.
Dynavector P75 mk3 phono stage.
Feeds into Lyngdorf 2170 via Nordost Red Dawn RCA cables.

My thoughts were that possibly the Dynavector is the weakest link and would pay most dividend on an upgrade but.....

What do I perceive I am lacking right now?
Really hard to say as this is highest quality analog front end ever owned.
Possibly lacking a little in sheer scale and dynamics? Bass is very very good, instruments are well separated and defined.
Just as an overall presentation I feel it lacks that final wow factor as a whole.
Not sure if that makes any sense?
Please comment honestly especially if you feel it is another area that may reap larger benefits. Or if should just leave well alone....lol.

Oh btw I am fairly sure it is setup correctly in regards to vta etc, at least to the best of my abilities right now. And yes setting it up correctly from initial purchase did make considerable gains in sq.

I have considered the possibility of something being wrong using balanced but this would mean 1 of 3 things.

1/ Goldnote wired their xlr plugs incorrectly direct at factory.
2/ Lyngdorf wired their xlr plugs incorrectly direct at factory.
3/ Wireworld wired their cables incorrectly direct at factory.

None of those seem likely but who knows and short of opening things up I am not sure how you can easily test for mistakes like that and how to nail down which would be the culprit if this is the case.

Could possibly be the cables being used.

@auxinput made the pair I've been using for the past 9 months, between a few different phono stages/DAC.   DH Lab BL-Ag with Furutech gold XLR connections.  They have always sounded superb in every integration.

What balanced cables did you try?

Only have one set right now
Wireworld gold eclipse 7.
The rca are Nordost red dawn which are traditionally supposed to give a leaner sound so I would be surprised if it was just the make of cable.
How bad it sounds I am thinking something a little more involved

Uberwaltz, a possibility that comes to mind, which could account for the symptoms you’ve noted with both the phono stage and the Oppo, is that the balanced cables are miswired such that their ground pin (pin 1) is interchanged with one of the two signal pins (pin 2 or pin 3) at one end. Thereby causing one of the two signals, as provided by the source component, to be connected to ground in the 2170. Which would adversely affect the performance (and eventually perhaps even the health) of the output stage of the source component.

If you have or can obtain a multimeter, check that each of the three pins at one end of each cable is connected to the corresponding pin at the other end. And also check that each of the three pins is not connected to either of the other two pins.

In doing so, it would be best to use a magnifying glass to view the pin numbers that are marked next to each of the pins, as their symmetrical layout makes it easy to confuse pins 1 and 2 with each other when comparing the two ends. And for that matter, perhaps the assembler became confused for exactly that reason :-)
