Could those who claim to have achieved loud volume from this help out with power supply and speaker specs? Would be much appreciated.

I purchased 3 of these and I love them. They only produce ~3 watts/Channel so you can't expect them to make enough volume to shake a room. They will, however, keep up with the majority of boom boxes on the market if configured correctly.. This unit operates on a D.C. voltage between 3.5 to 5.5 volts. It operates fine on a 5 volt supply. A lower voltage will decrease the wattage output so stay between 4.5 and 5 volts for maximum volume. (Either 3 standard AAA, AA, C, or D cells or 4 rechargeable cells) And, of course, USB power.. I use a voltage regulator (LM7805) and operate from a higher voltage. (12 v.d.c.) This protects the amp and gives you a large D.C. input voltage selection. By using the regulator, now you can use any good D.C. voltage supply between 6 to 35 volts without concern of damaging the amp.. As for speakers, this amp seems to work best with an 8 ohm speaker. I've tried 4 ohm speakers but they don't produce as much volume before the amp starts to distort at high volume. I've connected this amp to many different wattage speakers between 20 to 200 watts @ 8 ohms and it performs just fine. Plenty of volume to fill a standard sized room. All that can be expected for 3 watts/channel.. Hope this helps..

It will probably work fine with low volume of music and make sure you are using the right speaker impedance but to use it at high or full volume I think it will require a power supply of at least 20 Amp; The fuse use in the Amp is 30A and the manufacturers leave some room in the fuse value from 10% to 30% for the start-up current. Since an Amp has a big start-up current I will guest they use 30%, that means 30% of 30A = 9A, so 30-9=21A will be the require current for the normal Amp operation. Just make sure when selecting a power supply to check the constant current output not the maximum current.

Sorry - have to know how many amps or milli-amps your speaker is + how many milli-amps your power supply has too because they have to be similar. Power supply has to be at least as much as the speakers. Hope this helps a little....

There are 2 seven watt drivers and 1 fifteen watt sub-woofer so I would estimate a very clean and loud ten watts before any noticeable distortion. I don't run it wide open because that is TOO LOUD!!! 1/2 to 2/3 volume is loud. Below 1/2 volume is normal. Maybe about 1/3 volume for quiet listening.

The speakers are pretty good. I can't ride with the volume on full blast. Sorry I am unsure about the upgrade.

Sorry, I can not help you, it was a gift for my great nephew. At the time I printed one of the reviews regarding the volume setting, since that was the only troublesome issue. Look in the reviews for guidance. Good luck!

Karen, I think the design of these speakers are only for certain volume (major use is laptop). That is why the speaker power / volum is not designed so loud considering laptop use (most of the time) is in public area. My suggestion is that if you need more power for the speakers use the set that goes with power sub-woofer is the only way.Thanks,Thuc

The real question is do you normally run them with 200 watts of power?? The control is spec,ed at 100 watts. But for home use even to the most hearing impaired user Most folks will not use more than 20 / 30 working watts of power though the speakers are rated for 200 watts that just means that that is the peak excursion they should be able to tolerate without a failure. What is your amp rated at How many watts?? Knowing this how hard do you run it at?? a 200 watt amp run at half volume should deliver approximately 100 watts output power. I have 250 watt speakers and a 60 watt amp and can barely tolerate them run to 50 % past that I risk hearing damage and a visit by the local constabulary My speakers are really efficient. I am a believer that its not the power but the efficiency that rules. I do professional Sound reinforcement and rarely need to use more than 200 watts to the mids and that's to rock a crowd into the couple hundred. If you are truly using more than this consider building a more efficient system. My use of the volume control is to trim outdoor speakers rated at 50 w from an amp that outputs 25 watts

Thanks Kanje, I will keep that in mind. So far the only gripe I have is the lack of volume. If I could do something about that. Might keep ad a work computer only as I got it at a reduced price.

You should do some more research as answers vary. Are you running 2channel? Bridged? Read the instructions, I don't recall the output in each mode, but it depends on the resistance of the speakers. Seems to me 250w rms speakers will do fine with that amp...

Technically, yes, the topping amp can power those speakers. But, the sound quality is not going to be there due to sheer lack of power. You can increase the volume, and it will get louder, but the distortion level of the amp will be high. I am using it too power 2 Dayton 652's for my computer setup, and it works just fine. ymmv

The answer is, not bad. Not as authoritatively as the Anthem 200wpc amplifier it replaced in my system, but the fidelity at reasonable volume levels is good. No, it can't drive them to very loud levels, which is not surprising given the relative inefficiency of the MMGs and the relative low power of the PowerDAC..

Not sure. In fact, I'm not sure it has the power to output sound to anything bigger or better than what it has. I got mine as a gift .... it barely has volume and one speaker stop working on the 3rd time I used used it.
