Would changing to a MC solve my problem?

Dear @traudio : 46db gain is more than enough to could have over 95db SPL if that’s what you need but I think that your gain " trouble " is not about the V10 gain but around two things: first is the very low sensitivity of your Magnepan that needs a lot og current to fly along perhaps a impedance curve that could goes at lower than the nominal manufacturer spec of 4ohms and maybe your integrated unit can’t really handled with aplomb you want it and the other issue could be that you have a room surrounded of attenuators as the floor carpet and the kind of listening couchs and the like. problem is not in the cartridge/V10 but this is only an opinion about and could be wrong.

Sorry not give you a different answer you are looking for.

Regards and enjoy the MUSIC NOT DISTORTIONS,

The room is not the issue as the Digital input plays at an appropriate volume setting.

Thanks for the link. That's exactly what I was looking for. 

@traudio : Ok, then digital is ok so the problem is with analog and that could beaproblem in the V10 or in the H390 running analog.

Why insist I in the overall issue? because those 46dbs of gain ( repeat ) is totally enough for any integrated to achieve over 95dbs on SPL no matters what.

The designer of your  cartridge spec said:

" suggested preamp gain: 38-44db "

and you have 46db. 

With all respect looking for more gain makes no sense at all. Again, something is wrong down there. Maybe the loadimpedance or in the MM stage circuitor something around it.

You can ask directly to Hegel/Soundsmith.

Anyway, your " call ". I'm trying only to help you.

Maybe some one in this forum can help about with out need you buy a new cartridge.If I was you I ask and explain all to Hegel and if for them what you are experienced is ok then buy the MC cartridge.

What linestage are you using, and how much gain does it add to the signal driving the amplifier? If you’re using an integrated, the linestage section of many integrated amplifiers does not add gain. 400mV from your phono without linestage gain may not be sufficient to drive the amplifier section to full output needed to drive Maggie’s. Whereas the cdp makes 2V, more than enough to drive any typical amp to full output. So Raul is correct in that case.
