Fair points and intelligent question

As far as I understand the imputs benefit from hi Hfe
No so much for the current mirrors

Like you for same guide lines would be most welcome

On shielding

I am currently using a 304 stainless stell box (non magnetic)
and the boards are mounted inside a open top second box made with cooper
Noise is just not there but this IMO is in grand part due to the clever design and board quality.

Did see your nice build.
But for discussing proper shielding,
only the audible abscence of noise is not really a fact.

Tanks that is just beta....

Much smaller surface area for R3

it is a fact that with amp at max and ear glued to speakers I can not ear any noise when needle is up also a fact that I am not realy bothered by frequency above audible
low band with of ears and twetters take care of that.

I say buid Paradise to start with and then if you decide that improvment is needed no body is going to stop you to build new box

Propper shielding may involve Mu metal multiple layers as they do on moving coils transformers this can be had as A4 paper thin sheet from E bay or one can use EMC shielding Paint on multiple layer paper sheet all good stuff as long as one get to play a few track in between builds.

And yes, the Paradise is dead quiet, when shielding, grounding and boxing is done right.
Short circuiting the input makes the noise even lower. The cartridge has some Johnson noise too. Your DL103 with 40 Ohm is 4 times more noisy then the Paradise itself, Benedetto.
