I even see that they have a AD442 now! Just after that I have the AD430's LOL

I encountered the same thing when I bought my K30. A few months later, K35 then, AD42 by the end of the year.

I've seen sound systems in Jamaica using 100/100 dual poles and have no issues with the amplifier's performance. 99.9% of the time they play outdoors where the demand is far greater than playing indoors.



I'm sceptical of quoted output power, of cheaper Chinese lightweights, until I hear feedback  about real world results.

And by real world results, I mean on sub use, < 50hz hpf, at 4 ohm stereo.
When someone reports they have played number of gigs as above, and sub tone was "full/warm", amp remained fairly cool all night, no thermalling/premature limiting, I class that as a success.

I would not class the above, as a requirement for 1% of users.

yes massive problem in the electronics world at the minute, lots of items sat half built awaiting parts , automotive industry also,  that's why k20 are fetching up to  3k nowSleepy ,gutted i didn't get one when they were 2200 used  ,was offered one too :( only spoke about this today , tho these admarks do look good just need to see one being hammered on a reggae sound and a drum and bass hire out for many hours for a good few months  to finally decide 33 to 80hz on sub duty i personally set mine to

This is what I call, real world, sub usage, especially with pre amp, for Roots Reggae, and not many amps of whatever country of manufacture, can handle this without issue, 4 ohms stereo, week in, week out !!

Hence sceptical, until unit is tested and proven.

You may need to sway away from your circle friends and focus on Sound Systems in Jamaica. They play multiple times per week for years using CVR/Admark with no issues.

These amplifiers have already proven themselves year in and year out to be very reliable in the field. This is why, the majority of sound systems in Jamaica use them.

I've heard from many people that Admark and CVR are just fine for sub-bass duty (20-90hz). I know a few people who have had them powering subs doing this range for 20hrs per day for 3 days straight. This is for EDM music as well.

Really hearing contradicting feedback about Jamaican/West Indian usage, of these amps.

Yes, they are selling well, yes many sounds running them, but told mostly with 50hz+ HPF !?

On European continent (Esp France), where number of heavy Roots Dub sounds are increasing, and hpf 30-40hz is very common, amps like Void Inf8MK2 and Powersoft K20/X series are sought after.

When playing around with a CVR 3002 I noticed considerable weight added to the sound when dropping the HPF below 40hz. Just thought I’d say this as I saw some mentions before that they cannot do anything under 40hz! Only used mine on small inverter setups so not had a chance to cane it but then again I don’t play sine waves or want to boil a kettle from my amps so my feed back isn’t of use to some of you guys LOL
