Hi to all.
I'm new on this forum, although i've been reading a lot of threads about Class D, i cannot decide which one can be more suitable for my purpose.
I'm willing to make an audio system based on class D or class T amp and i would like to find from your experience which can be more suitable, and with the best price-performance ratio.
Power should be at least 100W /ch at 4 Ohm, better 200-300W, 2 channels for the beginning.
Thanx.

I have build some 41Hz com Tripath amps. 41hz makes un-assembled kits, and they are pretty cheap as far as I can tell.
You can find people to build these boards up for you at the 41Hz site:

There are some pretty good builders there. I'd check out the Amp10-BASIC 2x100W, Amp9-BASIC 4x100W and Amp11 +60W monoblock.

bobsnakke, you want assembled modules? If you have the bucks you can't go wrong building a Hypex UcD180. It will be nearer your power requirements too.

If you want to make it really EASY to do, get the Hypex 180s and companion SMPS module. "Building" an amp becomes little more than mounting modules to some aluminum sheet surfaces, and connecting some wires to terminals and connectors.
Extremely nice result, too, and price is quite reasonable.
Remember to factor in costs of
--chassis
--heatisnks (if required) and
--transformers and filter capacitors (or switching SMPS supply equivalent)
...when calculating actual total price. These last three can dwarf the costs of the modules if you aren't careful -- the majority of the material cost in many commercial amps is for the damn boxes that they are built into!

The sound quality of both the Hypex UcD180st and the Amp9-basic is exemplary. There really isn't much between them. Most of the time I run the UcD180 powering my subs and the amp9-basic is powering my mains, it being 4 channel I can run it with an active crossover for my mid and highs.
Tests that I did before I went full active. I must admit where the UcD180 is probably a more truer sound, there is something about the sparkle to the highs of the amp9 that make it great for running compression drivers and waveguides.
Its all good!

For jazzy939
at the moment i use class AB amplifiers, which are quite big and ineficcient for my purpose. i use to use-it at parties, that's why i need at least 100W. and of course, to be light, this counts when i have to carry all the time.
price for UCD or for 41Hz is still a little bit high for my budget, i will consider this eventually if i cannot find alternative. i keep searching.

i plan to use an old amplifier housing, in which i can retrofit a new existing amplifier which i will buy.

I would seek advice before going for a amp2 build.
"The AMP2 is an advanced high power amplifier. Building AMP2, requires considerable experience in building electronic devices. It is not suitable for "beginners". If you would like a simpler to build, smaller amplifier, take a look at our AMP1 boards or the AMP3."
That statement off the 41hz.com site is not to be taken lightly.
Amp9-basic is a relatively easy build, Iv'e built a couple of them. They are also great value for money as you get 4x100w into 4ohm.
http://minirig.org.au/2008/05/28/minirig-41hzcom-amp9-basic/
Using old chassis can be fun, Iv'e done it quite a bit with preamps. I don't think you will be able to use much in the way of old amplifier power supply components though, I guess it could be fun to try. I love utilizing old stuff instead of discarding or recycling it.

Hi Luka,
Nice amp2 Howto on your website.
If you know what you are doing maybe amp2 would be an easy build. But I think the topic of this discussion is more about assembled modules. If you were a novice kit builder I think amp2 would be very difficult for a first project.
I was going to have a go at Truepath but a friend of mine just had a very trying trupath time, it has taken him nearly 6 months to complete it. It's put me off, I just bought 2 UcD400

Hey it was my first one, 3 day to do all...I don't know...col said:Hi Luka,

Also no extra cost for 41Hz kits...
But if he wants assembled modules, that is up to him, there are few to buy...coldamp, hypex and many more, which can be found even here

right
i don't have the time and experience to buid one amplifier, even if is complete assembled kit, that's why i would preffer assembled one. seems that i found was looking for, i would need your advice regarding the choice. i found this site where they have for sale some ready modules for great price. anyone have experience with this site ? some feedback ? oppinions ?
