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.

@Robelvick.

Hooked up the OPPO via digital coax so can instantly compare the sq to the existing  xlr connection.
Have to say the digital is far superior in every aspect, and that is with a 15 year old Monster cable I had lying around.
Opens up possibility of taking a phono input via xlr.
@uberwaltz

Glad that worked for you.  You eliminate an extra conversion going with a digital connection.

Good luck on your continued hunt for a phono stage, and I'm sure you'll keep us all updated!

Best regards
Just going to copy and paste Keiths very informative email response to my question about the Herron phono stage. Obviously he is a true Gentleman as Slaw stated and would not see me disapointed in any way!

Hi Kevin,

Thanks for the note. I like to see, as a general rule in high end audio, an impedance ratio of at least 1 to 100 (output impedance to input impedance) when using tubes or solid state as loading the circuits down generally reduces the quality of the sound. I have seen similar impedance ratio recommendations from Audio Research and other high end audio companies.

Solid state circuits generally have much lower output impedances than tube circuits. 10k Ohm input impedances are a standard typically used in professional audio, but this does not work as well for tube based high end audio equipment.

The two 12AX7, three 12AT7 version of our VTPH-2A has an output impedance of 400 Ohms which performs best into a 40k Ohm or higher line stage input. Some people are using them with line stage inputs that are a little less than that with reasonable results, especially if their cartridge has a lower output voltage. Your integrated with a 10k or 5k single ended input would likely restrict dynamics substantially, even with a very low output phono cartridge. I can't recommend that combination. Audio is supposed to be fun.

Another thing to watch for is that some line stages (particularly digital ones) have a very low input voltage limitation which can cause overload (clipping) with some analog sources. That can sound nasty.

For the reasons above I design our line stages with a 100k Ohm input impedance and a wide input voltage margin in order to get the best sound quality from tube based sources such as phono stages, tape machines, tuners, and DACs with tube output stages. I wish everyone would do that.

I hope this short explanation helps.

Best Regards,

Keith
Quite likely then I am going to give the Manley Chinook or the Gold Note a trial as I do not see myself changing the Lyngdorf out any time in the very near future.
Will see if I can arrange an in home trial of either before spending money
