And i was also thinking about all this class D crap imposed on us in cunsumer electronics, ECO friendlyness is put before sound quality.

In sweden, you barely see an amplifier thats not class D nowdays, class A and AB is more or less a thing of the past unless you build it yourself.

This way the current through the input BJT will be the same and symmetrical regardless of bias current and offset adjustment. => Every amp will sound the same way.
Very nice incarnation 1 mA fixed input bias plus bias/offset CCS generators summing on 2,2k gate-source resistor. Similar like in your CFP amp, driven CCS in output stage.

Sonnya can you please send me the link where you buy Exicons. Thanks

When you run an amp with idle of 60 - 70mA, it would 6Watt per channel with +/-45VDC. It is only a fraction more than with Class D.
And with proper standby circuit it would be able to meet the requirements of the EU.
It can be that it is not as efficient as Class D, but class D also is inefficient at 1W. But regarding high power, no one can compete with Class D.
But for my use 100Watt is more than enough.

I would not replace my CFB designs with CLASS D until there is a huge leap in performance.

But let us return to the TSSA.

I will build it and make a PCB for it. But should it be std. mosfet or EXICON layout???

But they are out of stock.

I think it is the same production facility that make trouble in "the wire amp" thread.

Exactly, when and if, some sort of powered DAC having 24/32 bit A/D digital correction feedback. Even than there's no guarantee it will surpassed top linear amps.

Yeeeesss, Sonnya's PCB contribution to TSSA thread, greatly appreciated.

I don't know which to choose, do you have some preferences to any? I don't have a lot of laterals experiences.

Thanks, if need me, I'm here.

I read that yes, P-ch was delayed but seems they made them and both are deliverable.

As you are talking from Class D i just in soldering a IRS2092 Kit from LJM...No doubt that it will be compared to TSSA BIGBT HP.
