Congrats! The Anniversary Mods--regardless of cap choice--make a profound difference in the CSP series preamps. Though my CSP3 was born and shipped with the mods (and another modification) the CSP2+ I sent in for the Anniversary mods was really transformed, became a much better preamp and headphone amp. Even before break-in there is much to hear.

Day two updates:

I felt that the tubes that were in the output positions might be tired so I reached for a couple of NOS tubes from my stash to replace them.   Initially I put all the tubes back in that were in the CSP3 prior to the A-mods which were: GZ34 Metal Base, Philips E188CC SQ input and a pair of Siemens E88CC Grey Plate.  That way I could compare post mods to pre mods.

I replaced the Siemens with another NOS matched pair Siemens E88CC in the output positions.  This verified that the previous two needed to be retired.  At this point I will confirm what Lon said about the A25 mods making a fundamental difference.  This CSP3 with the A25 mods is an entirely different CSP3.  I don’t think that I can put it any better than he did: “mesmerizingly good”!

Next I replaced one of my DSR interconnects with a pair that I just received that have the Xhadow ends.  Because it was a .5 meter pair I put it between the ZR2 and the CSP3.  Another significant change.  The Siemens tubes that I had just installed had the typical edge of a new tube.  That one IC cable change took it all off and more.  Yes, the new tubes still have to burn in but the difference that DSR/Xhadow made was immediately evident.

For those who have a CSP3 and are wondering whether you should get the A-25 mods, even though this is only day two with mine, I will strongly recommend that you do.  Then give it the best signal that you can and you’ll see just how good these A-25 components are.  

I'm losing track of time, I think this is day four and I would completely agree with Steve's comments.  With this modded CSP3 in place the system is turning into a music monster! Unreal timing and dynamics, as for the rest... yes it sounds like I just got a more powerful amp.

When I started acquiring Decware products not all the components were available as they are now.  So looking back I would would recommend the following for anyone getting into Decware:

ZRock2 with all options + CSP3 with all the options.  The CSP3 with the Anniversary mods is a very versatile pre and an absolute killer!  So I would spend as much of my budget as possible on upstream components.  Then a base SE84UFO or another Decware amp of your choice, but it doesn't have to be a loaded amp, that can come later.  

If you ever hear something like the SE84UFO25 at the end of that chain it likely will end up being there.
