Externally, the smps seems solidly built, comes with a nice stainless steel case, and AC and DC power cords. I can't attest to the quality of the innards, I'll leave that to someone more knowledgeable. The power supply gets warm but not hot, and so far the cooling fan has not been activated. Tracking of the shipment from Modders is via the Sure website, the PayPal payment went to a Sure email address, and the recipients name is the same as on the amplifier board. Add it up, and you get Sure electronics as the vendor.

Oh, so it's a Meanwell clone, my mistake before then.

The shortest cables (none) following the lowest value pot that your source will still drive well (10k?). Or better yet, if the volume levels work out, straight in with small amounts (0 to -10db) of digital volume control from your media player.

Connect 5v to mute for mute.

I am assuming it is a Meanwell clone because there is nothing on the case calling it a Meanwell. The case is slightly different than pictures of the Meanwell, and the weight is listed at 1056g for the clone and 1134 for the real thing. Otherwise the spec sheet is lifted directly from the Meanwell. Both product numbers are PT-IP012, and the model number is S-350-27 on both. Because of the weight, I am guessing that the insides are different.

If it's the same SMPS as here:forum.zelfbouwaudio.nl • Toon onderwerp - 2 * 100 watt klasse D module.

Then I can only say don't buy it. Reports are that the fan in this device is super noisy and the guy in that thread reported smoke coming from it.

I'm also guessing you better pay those 10$ more and get some (better) quality.

Edit: just set the gain to low. Much less hiss now in idle. (barely/not audible when 10cm from tweeter)

The Google translation isn't that good but it sounds like they are discussing the contact of Meanwell to resolve the problem so I guess that is who made it("Je kunt beter Meanwell mailen"). The pictures don't look like my supply at any rate, and the fan has yet to be activated so I can't tell if it is noisy. Definitely no smoke so far and it is working well.

In hindsight, you are probably right if the quality is indeed better.The difference in price is now around $13.50 US, not that much if the Meanwell is a better unit.
