hifiman,

Sorry if you think I'm angry. It's a matter of haste.  All contribuitions are wellcome. 
But somethimes the discussion goes so far from the topics that the objectivity is lost.
If you observe, this is the third time I ask about.
And I need a consistent feedback for an eventual decision, nothing more.

Thanks

"Like anything audio, the cost is not equal to the improvement" - - so true, Elizabeth!  You have to have been born with a pretty funny itch in your brain to spend like we do, but who's to judge what brings joy to one's soul?
$7500 for a P15 is too much for me.  I’ll decide to be happy with what I have.
You also could try the Accuphase PS 1230  or the little PS530.

A friend of mine has one for years and it’s been the endgame for him
