The smartest thing is likely to stick with the Modwright PH9.0X phono. (IMO)
I had the Sim/Moon on the short list, as well as Sutherland.
It sort of depends on the cartridge though. If one is playing many cartridges then the Sim/Moon has combo that can be selected from the front panel.
If one is inclined towards MI or MM then I doubt that the transimpedance are “the go”. I am pretty sure that the Sutherland requires only MC… so no MI or MM.
And there is the SUT crowd. So whether it is “build in” or outboard, then that drives one to a different set of phono stages.
If one already has a nice phono stage then a good case can be made to just stop there.
My system has zero hiss at full volume, except with the phono stage… and the old ARC is limited to MM and 42dB (or maybe 48dB) of gain. And the ol ARC PH2 has a fair amount of hiss and low level noise… which starts to get audible a bit higher than where I normally have the volume at. So it is not bad, just it’s not perfect.
And I am limited to using only High Output coils.
Hence; I decided to upgrade the phono stage. And I have more cartridge options available.
If I had something like the Modwright PH9.0X phono, I would not likely have done so.
I’ve liked all my tube phono stages better than both of those units.
I got a used tube phono stage. And most are not overly “tube hungry” like a power amp can be.
