From the comments section below the video:
So, PS Audio Service here.
That repair fee is either a cap for parts and labor OR the flat fee for an overhaul/repair and a 1-year warranty.
The Quintessence you mentioned no longer has parts around to fix it/fix it reliably. Our guys will spend 12+ hours on board level repairs in those cases, hence the $750 cap, as the labor cost will most likely reach over that amount.
We also do not charge if we cannot repair. Shipping back and forth is a cost in itself, but if we are hesitant to take a product in we make it clear that it might not be repairable, so I would have to say the risk is known before sending the unit.
Did I miss anything? Cause I’d really like to make things clear here. I think our service is pretty good and would like to make sure most others feel the same. (I know you can’t win em’ all)
