Eros Phono kit is in transit - any capacitor upgrades?

[Henry2011]

Some of us have Eros Phono kits in transit.  I would like to do any recommended capacitor upgrades during the initial build (as I did with my SEX amp).  What capacitor (or other component) upgrades have proven worthwhile in the Eros Phono?  Are there any other mods to the Eros Phono that have shown a performance improvement?

My phono cartridges are relatively high output Grado moving iron (in the 4mv to 5mv) range so I am not considering SUT installation.  The Eros output will go to my SEX amp input.

The high voltage supply is regulated and isolated with a C4S.  The heater supply is regulated as well.  The most important capacitor in the circuit is the output capacitor.  The output stage is designed around the Seduction final stage.  PJ has said that a 0.47uF value there is sufficient to cover all audible frequencies.  The 1.0uF that is supplied with the kit is considered an upgrade not because of the increased value but because it is a PP film cap.  

I was musing online with Paully about the use of two 0.22uF 600V KK Teflons (in parallel to achieve 0.44uF) there.  These caps are very nice sounding and unusually inexpensive.  PJ urged Paully to try just one 0.22uF at first.  The indication was that a second might not bring any additional bass information to the table at all.  Bass is what is sacrificed with a lower value at this point of the circuit, nothing else.

So my obvious suggestion is for you to buy some of these, break them in as I have posted and report back.

Grainger, 
Thanks for the info (especially the link to cap break-in techniques).
