Hi all, Im looking for a premade amp around 30-50W that will drive the compression drivers (crossovered at about 1 khz) as part of a triamp setup.
There seems to be a range of options. Which of the following is the best route:
buy one of those topping/tripath ebay amps TA2024
buy a premade china amp made from TPA3116
Get a conventional pa power amp: https://www.thomann.de/gb/tamp_s75.htm
the hifi power amps appear way out of my budget ($200 - willing to stretch to 300 if light years ahead).
any other suggestions?

If you have compression, you probably have active filter. A unity gain amplifier is a very good choice. RJM Audio - The B-board Buffer Stage the S/N ratio will be improved by a magnitude.
The high damping factor suitable for cone speakers may not be ideal for compression drivers, and you may want to deliberately build out the amp impedance with a resistor to soften the chamber resonances. Of course, that would reduce the power available to the driver but you usually don't need a lot of power for horns.
I find the HF to be critical in perceiving harmonics and detail. I would not recommend a Hi-Fi amp unless you're going to use the set up in a home environment. Even so it would be far better to get a high quality power amp (Crown, Lab Gruppen, etc.). I don't have any experience with small chip amps in a PA scenario, but there is a reason for that. The PA amps are made to bring a consistent performance upon hours of heavy use.
