Low budget compact class d power amp

[gasolin75]

I wouldn't mind trying a much more power full compact (cheap) class d power amp for my triangles speakers

Such an amp is not impossible to get for around 100 euros

The fosi audio v3 integrated amp is 109 euros and up to 2x225 watt in 4 ohm, what if i only want a power amp ?

Fosi audio v3 monos are 300 euros for a pair and is a little more then 100 euros, shure the fosi audio v3 only has a volume knob in the front compared to a power amp like the fosi audio v3 mono and it only costs 109 euros

So why isn't there any 2x200 watt (or more) in 4 ohm power amp that costs less then one fosi audio v3 mono (under 150 euros), the power amp version of the fosi audio v3, a more no nonsense version of the fosi audio v3 integrated amp ? (don't pay for the volume knob,potentiometer or what they use for adjusting the volume, either save the money do to not having a volume knob or what you save can be used for better sound, better binding post,better power supply, better internal components or better ventilation holes)

Shure the v3 mono's might for the price have a little more power,control and mabye better sound quality (the last thing you would expect because they are the same brand and the monos costs about 3 time as much as the integrated amp).

Is the monos worth the price difference if both sound good and are rated for over 200 watt in 4 ohm ?

Not so much that 300 euros is a lot but the fact that both are rated to have over 2x200 watt in 4 ohm (bot might play about the same in 8 and 4 ohm) and sound good

Is there new power amp (not diy) for way less then 150 euros (mabye between 109 and 150 euros for the integrated and one mono power amp) with power and good sound ?

Sooner or later you hit the floor and can't go any lower in price. I'd say you are already talking around that level.

Given the Triangles in your sig, I doubt you need that much power, anyway though I couldn't find measurements. I wouldn't worry about it if I were you. Have you got measurements that say the Triangles do need that much power?

My advice - don't buy "cheap" Class D amps. They will be garage-built by someone who will take no responsibility if it blows your speakers (or your source) and will likely be gone in 6 months. Even "Purifi amps" offered on Ebay, etc are based on Purifi's cheap Eval(uation) board and not built using best components and associated kit - power supply, etc.

Either spend decent money on a reputable brand or buy a good used non-Class D amp with your €200 - but it will still likely to be pretty poor unless you sniff out a genuine bargain and pounce on it! Good luck anyway.

And be amazed to find out how good this is...
Balanced, add an old laptop power brick 19-24 vdc...
and an fine wine box, white or red...
It does not get cheaper than this...

Right now, there are two basic options - Chinese Class D integrated amps (have a volume pot) that are well-reviewed (Fosi, SMSL, Aiyima, etc.) and the Fosi V3 monoblocks (no volume control). I built a lot of 3116 and 3118 amps back in the period where those boards were not getting used by SMSL or others. They sounded pretty good, but I was never really happy with the DIY look. Some folks, of course, were able to make their chip builds look beautiful. Depending on your skill set, there are good boards out there for self-builds, this may or may not be attractive to you.

If you don't need a ton of power, just get a Fosi or Aiyima product with a 36v 5a power brick and call it good. If you are using a preamp, max the amp and use the preamp volume control.

If you need very loud, the Fosi V3 monoblocks are a good way to go, with separate 36v or 48v power supplies.

I think we all expect for there to be more "pure amps" from the Chinese and other makers soon, following on Fosi's success, but those will no doubt take a while to come to market.

For significantly more money, there are the various "just an amp" options from Schiit, that can be used either as monoblocks or stereo units. Not class D of course.

You could also go for a tpa3255, many boards on line...
I used ti 3255ev evaluation board in this one...

Not diy please

I have small standard class d amps

I wanna have,try this 200 watt in 4 ohm amp(s) that you can get for not a lot of money

Higher dynamic head room, more power to prevent distortion and when the amp goes over to a more sharp sound, also wanna try a much more power full amp to hear what it does for the bass on my current speakers, the bass needs alot more power to sound clean and punchy then bass light music like classic music, i have had experience that a very power full amp can set the bass on fire (meant positive).

It's more and addition to my system, nothing i think will be a replacement of my current amp, because of that and because i don't at moment have a budget that say €300 for a pair of fosi audio v3 monos, im sticking to the €100 ish price tag

Even when searching for used pa amps to get the power, i couldn't find anything at my place (Denmark) i wanted to buy

 

[Joe Smith]

I think your current budget is out of line with your power needs, frankly. $250 and up would begin to get you there. Short of a DIY build.

If DIY is not an option...you should stretch your budget a bit I guess.

You can get that for the money (+ shipping)

only cons i have with that amp is pop sound when turning it on,off

 

[gasolin75]

update my amp has preout

BUT although it works with a subwoofer it doesn't with an amp, meaning volume on my amp does nothing, i have the use the volume from the unit im connecting to my amps pre out

Meaing i can't set my amp to 12 o'clock and then adjust max volume on the power amp or integrated amp, the volume on my marantz amp don't work

Connecting a powered sub + passive speakers both can be adjusted in volume using my current marantz amp

What happens if a rosé case is used instead?

The sound gets coloured to much.

What kind of amplifier is it and are you sure that it has a pre out and not maybe a line out?
If it has a line out, then the controls on the amplifier do not perform any function on that output.

 

[gasolin75]

Totally screwed it up, it only works with a subwoofer or if use my amp as a preamp and use recorder for sending soundpowqer spakers or power amp and then use the connected speakers or amp to adjust the sound

It would help to make a sketch of what you want to do.

Are you still using a PM6007? If so yes the only pre-out is the subwoofer output; the record output is fixed line level. You can’t use that amp as if it were a pre-amp with a separate power amplifier.
