I've been told by number of Jamaican Reggae sounds, who have both Powersoft K20s, and Admark AD42s, comparing both amps, side by side, playing 2x 2x21" cabs per channel of each amp, the Powersoft produce more SPL, however the Admark have a warmer sound.

This seems logical to me, and what I would expect, considering price difference.

Makes used Admark, worth the price, to me.

We were unable to determine what makes the sound quality so bad but If you take an oscilloscope the waveforms on the output are very ugly.

Horrible in every audio meanings :-)

I am talking about this comment about the ad442 specifically .

What do you mean by not the best sound?

When we compared them to MC2 E-series, Powersoft K series, Linea Research and FFA the difference was negligable.

The only one that smashed all of the others out of the park was the MC2 Delta series and that seemed to be way better than all of the other amps we tested, with the same signal on the same box in the same position with the same gain.

Can you find this info?  I bought 2x ad442 for backup amps etc and they worked so far on low mids and bass but not the best sound.  Worried to use them or sell them somehow or keep for emergencies.   Do the other admark amps work fine without any anomolies?

Please report you finding. 442 looks too good to be true.

Do you mean the Admark ad442? I was curious about this model if you have comparisons between that and the other models I’m very curious .

I asked quite a lot of questions about amps , before i pulled a triger( bought some)Thanks Stef.
Its by no means Armonia , Lake or any other pro environment , but its ok , there is even some FIR . 
They can and do higher end of spectrum , but i don't think they sell a lot  , its well established market .

@Marjan

its indeed AllDSP (SBD44). It works ok. Fast but very simple UI, and for me personally not enough capabilities processing wise. The LCD of the amp is also quite limited

I now run some CVR 3004 DSP which are basically the same amp as the AD430 with a different DSP and some other small tweaks. Its the same DSP as used in the wharfdale DP-F series. I am not sure which manufacturer makes the DSP, but its looks nice and works nice.
