I think you need to spend some time with the "search" facility on this forum as there is an enormous amount of info available for what you might be looking for.
Also try "Eliot Sound Products", which is another great site; and he has pcb's available for his design's and some very informative articles.
Have fun researching.

a 50+50Vac 1200VA 3.5% regulation transformer with +-75mF smoothing and 6pair of MJ21193/4 should give 450W into 4r0 and 800W into 2r0 and drive a 60degree phase angle load if you can keep the heatsink (& Tc) cool.

4pair and a 700VA 4% transformer with +-45mF will give >440W into 4r0.

Lme49810 driving 5 X A1295/C3264 Sanken pairs can do the job.

Is there any 1500 watts speaker?
...160 volts rails should be needed for that power into 8 ohms.
This is not very realistic.
Bridging 450w/8ohms , 750w/4 ohm capable could be better but not forgetting that a speaker is not a resistor but a more or less reactive load.
To be reliable, such a bridged arrangement should be able to produce more than 2000 watts into 4 ohms. Which is 4000 watts peak.
Does not sounds very like a diy project.
Though nothing is impossible.
90 volts rails, four to six pairs of high power devices . Not to forget current limiters.
You can google Rotel RB1090 (open schematic). It is such an amp.
Better to be a little experimented to copy it .
The pic i show is this rotel output driven by a lme49810 which is a +/-100v driver chip.
I plan to go up to 90 volts but did not do yet...

There are several threads here about the lme.
