Best DIY power-amp/kit to build?

If you can build your own chassis, I would say this module, based on the well known myref amp found profusely on diyaudio, is the best bang for the buck module. I have not bought this exact one but have very good experiences with the myref amps.

The akitika looks like a classic good chip amp implementation as far as I can see but I agree that the the price for everything included is outstanding.
The myref amps are usually a level above the classic chip amps.
 
Suggest you look at the 'Leach Amp' as a start point.
A) Leach Amp Plans - Part 1
B) Leach SuperAmp Plans
An 'oldish' design but also a VERY good one.
Well respected.. by any yardstick.

I'm sure this is a good amp but the age makes it trickier to find the bits & pieces.
The Atikita is exactly the sort of easy all in one pack a first time DIYer needs, IMO. However, it is too pricey for a 3 way tri-amping project.
 
There are Leach clone BOMs using modern components.

But for a 3way active, a Leach clone build is not cheap, far from it, it tends towards the expensive side, due to big heatsink, large PCB and many components compared to similar 150W ClassAB amplifiers.

Look alright. For the record, in case the link breaks, this is a
Classic lines LM3886 dual-channel +LM318 AMP/ DIY
for 52$ + 12$ shipping.


So, what does that require to work? A power supply, some RCA + speaker connectors and a case ? Is that it ?


Thanks
 
Hi RickDangerous and all others,

Three to four years ago I bought my chip amp kits from Peter Daniel at Audiosector. I allready have tube amplifiers for my Hi Fi and have tried out several SS amps (so I am playing a lot of music). I believe the Audiosector kit to be one of the better, and most evolved, chip-amp kits around.
For my costs: I had enough caps for the powersupply laying around and needed "just" PS transformers, cabinets and cooling elements. I have recirculated some small fins from my old, small, Sentec mono's.
BUT: I haven't gotten around to piece the amps together yet. There's been too much going on in my life these past years. I've got everything I need now, except from time, to make my double set of Audiosectors for bi-amping my speakers. DIY Chip Amplifier Kits, PCB's, Components and Information.
There's many other very good suggestions in this thread now. A lot has been added recently that may bring other options for the best to make for your money. l will make my Audiosectors in the near future and evaluate them.
My own ideas for possible projects in the far future: I must say that I have been very tempted to build the Hiraga 50W Le Classe A, as described here: Jean Hiraga's Super Class-A Amplifier knowing how excellent the 20 and 30W versions sounds! I might also consider building the First Watt F4 to bring more power from small power 45 DHT SET amplifier later on, in the far future ;)
All the best for all your future projects;)

Hi Aril!

A few things to consider...

1. If you are not that experienced, be careful with amps that require your own personal choice of components. If you buy a pcb only and then have to decide which transistors, which capacitors, resistors and so on to buy, you will get into trouble because there are so many different choices in todays market. If you buy a kit you can at least assume that the builder is experienced to some extent and everything is already well thought out. Besides, some unique or special parts are sometimes difficult to source and if you end up with some kind of substitute you will always ask yourself if this was the right decision...

2. There is definitely no such thing like a "very good amp" by itself. It all depends very much on system synergy. One example: At the moment I have an old Linn LK100 power amp and one small diy-amp, build around 20 years ago (not by myself). As source I have my notebook and either a Echo Indigo DJ pcmcia soundcard or a Fostex HP-A3 DAC/headphone amp. Both units sport AKM dac chips. Now, the Echo with the diy-amp sounds flat and a bit technical, not very musical. The Fostex with the Linn amp sounds a bit constrained, a bit nervous in the highs and like something isn't quite right. But, the Echo with Linn sounds very good! And: The Fostex with the small diy-amp sounds also VERY good! With these combinations everything falls into place and sounds convincing, but the other way round, something always bothers me.
Ok, which one is now the "better amp"?!

3. I build serveral amps before, but there was always the need for something more convincing in all areas. Personally and from my point of view I would consider the Avondale NCC200 (if you can afford them; I'm very familiar with Naim amps and I like them a lot, but I always found the upper midrange to be a bit grainy and if Avondale managed to better this, this would be a very nice kit indeed). Also I would like to try the AmpsLab Lm60. The (short) desciption of the sound comes quite close to what I'm looking for. Sure, a Pass F5 would be an awesome thing to build, but as said before, sourcing all the parts and building such a heavy enclosure might be not that much fun if you don't have the know-how and all the proper tools needed. AKSA might also be very good but I can't afford, period. The SKA GB150 looks like an interesting kit, too...

You see, hard to decide. In the end you need to build at least a couple of amps to see what you get with these kits and then decide which one to keep (or: to build next...).

Hello

There is the Naksa amp modules, I have the 70 watt version and it sound superb.

That is WAY to much money for a diy amplifier kit. Why pay that much money if here We have some good designs and kits, just to name some: Nelson Pass F5, Anthony NXV200, Aussie amplifier and one from Lazy cat that are excellent amps and the best of all...They are WAY cheaper than the NAKSA.But that is not all...We still have so many diy amp kits all over the net that are very good ones and will outperfom most of the commercial amps. I would never pay that much money for those Naksa amps and I bet you some of the above amp will outperform the Naksa amps.;)

PS: These Naksa amps reminds me of the so well known "Gaincard". that people paid thousands of dollars for those amps.:joker:

First of all, I am real noob. I have basic electronics knowledge, mainly digital circuit but not analog. Build a headphone amp before with a complete kit, and did some mod by changing caps and resistor, adding filtering caps etc. Currently own a pair of emotiva xpa1 monoblk pair with dali ms5 speaker. But feel the amp is not what I want.

I like a sweeter sounding system, thick mid, prominent bass response, airy high, good separation, large staging and transparent. I still remember I once had a system sound like that, power amp wise it's arcam p9 power amp.

Now looking to start a power amp project, it has the be base on balance, symmetrical design. I saw a few lm3886 gain clone balance design but it doesn't seems to be sym, just a 2 sets of amp one handle amplification of +v input and the other -v input. (we call it bridge??). As for SuSy, I can't find any stable design that I can follow, with PCB component kit available.

Just few days ago I start looking at pass aleph-X100 and F5X, its not cheap and a lot of effort needed to build them (I don't have osciloscope only a dmm). I wonder if I can handle them?

Hope some experience builder could give some advice.

I would suggest this kit:
Ground Sound

Kit building instructions :
http://www.groundsound.com/pdfdoc/Ground%20Sound%20-%20SPA1000kit.pdf

You only need a box with some cooling profiles, and some plugs for connecting the signal, speakers and power.
I have been listening to music with these modules for some years now. And they simply do the job great!
If I hear the sound become anything else but enjoyable - then it is the fault of the recording, x-over, speaker-units... etc etc (MPO).
They are very solid build and simply amplify the signal, even though the going gets rough (low ohm, high volume etc etc).
Some might want more power - but then again, this is the second smallest module available :D
If the Guides on the homepages is followed and read carefully - which mean to remember and twist the cables, solder proberly etc etc. Then everything should work fine - I did with all my 6 modules in my newest build, and they have been performing flawless for the last year now.
I know that sound is a very personal experience. But when it comes to power amplification, I think these modules are hard to ignore.

I don't want to sound predictable but wh
at about a good gainclone? You can find assembled or not kits or pcbs on ebay. For a little more money a hypex module class d. If you want a class a amp then a scaled down version of a pass labs amp is it
Clones kits of these are available from the web ebay and of course diyaudio site. Look at the amp camp amp for the simplest.
