I never said the amp would blow up, yes if you coupled 100Vrms into the input you may damage the protection devices or overheat the input transformer but I doubt any sane person would connect it up to a power amp or power line on purpose... clipping produces objectional distortion so I choose to have that be impossible in system.
Look, I have no intention of any markting BS. MSB makes less than 1% of our revenue on products other than DACs and OEM contracts. I only step up to the plate to design something like an amp when all the avalable products are difficient in one way or another and we have need of it. I have zero interest in lying about technicalities. Yes a calibrated metrology KVD is the worlds highest performance 1000v amplifierless DAC but that fact alone does not make it suitable for music reproduction. Tossing hypotheticals about does not change reality.
I must say that you seem very defensive, did a grandkid poke you in the eye at Thanksgiving dinner? Flames usually accompany smoke, do you have something to hide? Nothing I posted was inaccurate so I don't believe I deserve being called a FOOL.
BTW when is any electronic component off the table when a designer sets down to design a product? Every DAC we sell has multiple transformers throughout its circuitry. RF transformers isolate external data busses and impedance match clock transmission lines, micro transformers do level translation or isolation for voltage islands, power transformers are used to generate power supplies, MF transformers are used for DC to DC converters, ect... The only drawbacks to designing with any transformers in my view is cost and size, they tend to cost more than any other circuit component and consume more space so I usually attempt to design them out of products that have a low cost BOM constraint or size constraint. My view is that a designer should test and choose the best architecture and componets that fit the relevant design constraints, not reject possibilities out of hand because of some irrational belief or fear. Just because a box has a transformer in it disqualifies it from being called a DAC in your view? I'm curious for you to explain your position on this...
Obviously I can stand the heat or I wouldn't have a product... Being terrified of being caught in a line and being dragged into a storm has never stopped good sailors either... fear is what keeps people cautious and alive.
