any update on the performances of Joule V power supply?
thanks
thanks
Is this a code for the Little Dot headphone amplifier? I don't get the point. Perhaps it represents an earlier or later period in your life.

I made a statement that I retracted as I need to do further research.
Sorry, just making puns: point, dot, period, etc. (I do that sometimes...)
At 50 hours or so it does go back down hill regarding the sound. The magic leaves. I am around 90 hours now and it sounds better but not the magical sound I had around 24. I expect this with burn in but I have had things do so-so, some hours later sound unbelievable and then coast down in sound, never to return to the refinement and very fine rendition of sound that had been experienced. So I wait and let it run.
Forgive me if this has been addressed before, but I've wondered about this for a while: Has anyone reported the results of metallurgic studies at the light microscopic level for electronic parts (cables, wires, etc.) at various stages in the "burn in" process under controlled conditions? More specifically, are there any microscopically visible changes in the structure of metals during the burning in process? This is a knowledgeable group; someone probably knows the answer to this.
Wow, I am posting to myself. lol
I am using some Sylvania great glass (the coating inside the glass) from the 1940's, 6F8G with great success. Great transparency, dynamics and layering with the HE1000 and using the Mojo V power supply. This Mojo goes up and down as it burns in (caps forming etc.). I am still listening to a lot of DSD via the Hugo (DoP) because you can really pick out the differences in sound with the amp and setup and I find it is hard to listen to some music do to the lack of spacial cues, when you can hear them in DSD but there is plenty of DSD out there that isn't very good also. For the IC from the Hugo to the micro I am using my own pure silver IC (99.99995).
I do find I like the coated tubes more than the clear glass. In the past I did not like the GE grey glass and still don't in 6SN7 but for some reason in the 6F8G they are fine. I have the round plate black glass also and the grey, IMO, is as good.
@jamato8
Still not getting a sense of how you feel about the Mojo power supply and the ZOTL...have you got a sense of it as of yet?
Thanks
Benjamin said it takes 300 hours to start hearing how it does for the sound and 800 to be fully burned in. It was up and down for a while but sounded better now. With the investment that it is, I want to be sure on my impressions before making an solid statement but right now I am getting a very, very realistic, dynamic and for lack of a better word, clean sound. All music, not sterile and smooth but with edge when needed. The HE1000 do not lack any dynamics at all, none. I would not want less dynamics but would not want more.
