Well, if that's  the case, I don't trust it, Snowflake!
Am I the only one uncomfortable with the number of new models Admark puts out, compared to CVR/Morin? Their K 30, K35 and AD 42 models are essentially the same w a 10USD difference,  but power claims are hugely different.

I think Admark OEM the amps for CVR and Morin.

Admark has become very popular in which, they are capitalizing on it. The differential in terms of output of the K30 versus AD42 is a mere 1.85 dB gain @ 4 ohms per channel. Those that must have the most powerful amplifier Admark offers will buy it.


The 4-channel version of the K30 would consume around 60 A (240-V) to 120 A (120-V) all channels driven at 4 ohms per channel (continuous average power). I doubt it would be possible to achieve the output it claims offering the same footprint (chassis, power cord, etc.) in a 1 rack space unit. The current demand alone would be the biggest challenge for the majority. It would make sense to just buy two units and distribute the power amongst two circuits than trying to achieve that type of power on one circuit.




Best Regards,

I always heard they were Morin amps rebadged.
However the many iterations Admark has would lend credence to Snow Flake's statement...

I will be picking up a K420 within the Autumn season to power four double tens for mids. It will definitely be the Morin and not Admark. As I mentioned in the previous K30 On The Bench review, I cannot justify paying twice the shipping rate in which, I would be subjected to buying the Admark over the Morin.

Best Regards,

I don't know for sure. It's also possible that one company has licensed the design to the other and there is more than one factory producing amplifiers of same design. the cvr and morin amps I have don't look like they have come off the same production line - differences in a few components but also lots of small differences in assembly - glues, chassis screws etc.

Morin builds in house as with Admark. You would be surprised what people will say when they have something to sell. No company can claim their designs are originals as the amplifier is China's modified version of Powersoft.

Cvr and sinbosen use a large output boards with the capacitors local for each chanel, and a small powersupply board, whereas the morin/ admark uses a smaller output boards, and a massive powersupply board to drive  both chanels. Don't know which will better for long term reliability yet!

Best Regards,


When you say modified, does this mean "modified for cheaper production, using cheaper parts" ?

As I have seen Powersoft K20 draw 34A @ 240V, driving 2x 8 ohm drivers per channel.

This suggests to me an extremely well built and designed amplifier, and anything built to cheaper price, would obviously  not be built to same standard.

I had missed that the sinbosen d series are the same design as well (they also do a k series which is different internally). all four companies produce amps that are identical in layout. most obvious difference is the size of the capacitors on the output boards.
