Plethora of Pinjatas / SET P amp(s)

These:


I bought them, in fact, a friend of mine boight them for me, but the speakers remained in the Paris area in his apartment. In the meantime friend moved to another country (job) and did not have the time to get back to deal with the speakers. Didn't want to ship them, me too. So we are awaiting some convenient moment (his holidays) to arrange their retrieval...

My amp sounds fine, offset and bias very stable. Same spooky sound as XA252, for most purposes. Wonderful amp, but I am big fan of XA252, so go figure.

It did do the "self turn off" again. There must be bad joint somewhere in the switch, (shurter so unlikely but still possible) the CL 60 soft start assembly ( totally possible) or rail wiring.

Getting ready to replace this temporary power supply with dual mono which will likely undo the problem anyway, but still...

No, let’s take it off the rails completely…….with other amps….😂😂😂😂😂

The last two days I’ve done a very long shootout between my S.B. and my XA-25 (hey, don’t judge me, I bought it before Choky got the 252 design done.)

The Singing Bush absolutely delivers the detail that the XA25 does WHEN it is driven directly by one of my dacs. In fact, the two SIT amps that I have deliver “ a spectacular wrap around the head thing” as long as they are directly driven. Not even a buffer (in my system) can be in the chain or it ruins the spookiness of the SIT. With my XA-25 I can have a buffer / line stage and it still delivers its epic soundstage. The SB is much closer to the XA than I would have thought and certainly is its equal when I use it properly in my system. I really had to figure that out before I heard the SIT “magic”. It has refinement and tonality in spades and when driven directly rides that very fine line between smoothness and leading edge attack that I did not hear when used with my buffer / gain structure. I’m lucky because I have multiple toys to drive my amps with so I was able to quickly find a combo that allows Alex’s design to certainly match an authentic Pass product, which of course these amps have very different distortion profiles.
 
Vix, funny you mention that because I’m thinking about dusting off my hotrod DCB1 because it is also the only thing (or passive) that doesn’t destroy the “magic” with my two SITs.my uber, (ASR approved 😂😂😂😂😂j, performing Schiit Kara in buffer mode almost destroys it.

Interesting. I'm wondering how Iron Turtle would perform in that regard. Keep talking myself into that one!
