They are using circuits that we pioneered- yes, they are competition but they've yet to break the price barrier. So we have amps for about 1/4 the cost of theirs that are more reliable and sound better.

Of course, they like to use negative feedback and don't use class A.

There is a sort of 'trap' with OTLs where the designer tries to make the amp do things that it really shouldn't be, in an effort to show off what the amp can do. If you just accept the fact that an OTL might have a higher 'output impedance' (I put the term in quotes as under the Voltage Paradigm, the term is misused) then the thing to do is to look at whether that is important and what are the consequences.

Using negative feedback makes the amplifier violate a fundamental rule of human hearing, IOW it exacerbates odd-ordered harmonic distortion. The violation is that the ear uses odd-orders to determine how loud a sound is, so such an amp will sound artificially louder and brighter than the actual music.

This means that any amplifier built in this way cannot sound like real music!

So if a speaker demands this of an amplifier it in turn cannot sound like real music either. Since the Einstein commits this sin, it will never sound right. That, other than the price, is the reason we beat them on a level playing field.
