I would like to find out for myself...
I see the modules are used in Martens Mono blocks, so they should be fairly OK.
Have sent a question to Abletec if it's possible for DIY'ers to get hold of some.
No response yet, but did it today, and it's weekend, so let's see....

Have made some monitors with a combo of Groundsound and Hypex which turned out great.

Whats your project?

Brgds,

Hi,

You might like to check out the following link, these 4 available modules are available to whom has interest. So also available to a DIY persons like us.

ABLETEC / Profusion UK

Best,
Wim

PS. I made an amplifier using the 2x90W module, works perfectly.

Thanks for the link Wim,

If they cannot sell directly from Abletec in Norway I might have to order from the UK then

Would the module you used be the ALC0180-2300?

How is the sound quality?

They are much cheaper than the Hypex modules and have onboard PS.

Yes, that's the one I have.

I don't have an opinion on this. Why not? I do have a Pragmatic class D amplifier and wrote something about it in the AudioXpress June 2009 issue. This amp is compared with the Hypex UcD180 using the LM4562 opamp, and the owner of the amp thought as well, the Pragmatic is in specs, outputpower, noise, THD not even close to the Hypex (the Pragmatic is so much worse), but the Pragmatic sounds more envolving. My favorite pianomusic is as good as it can be, but than its comparing Lang Lang with a Volodos, Richter or Sokolov. Lang Lang sounds virtuoso, clear, impressive, and so on, but he simply just doesn't get to the hearth of the music, he simply does not know, but he is enormous popular and you are not allowed to talk bad about him. The same people forget about a Volodos or a Sokolov. Same for Hypex, it is popular and used by so many DIY enthousiast, the Pragmatic is not popular at all and not used by them. I guess you will get my point. In fact everyhting is matter of taste and (maybe) believe

I've been wondering about the Abletec modules for a while myself. Not much info on the net regarding diy users. I guess the only way of knowing for sure is to try... So I'm about to order a pair of ALC1000's from Profusion.
Hopefully in the next month or so I'll be able to do some comparisons with my
UCD400/SMPS400 monoblocks....

The Abletec modules had been recommended in another thread, where I had been asking for proposals for a 3-way system.

The ALC0180 seemed to be such a good deal to me (less then 100 EUR for a stereo board, PSU included) that i decided to order two of them at profusionplc.com.

The parcel arrived today, about two weeks after ordering. Hopefully I'll find some time for testing them this weekend.

Meanwhile some pictures:

For those who are interested. In one of the upcoming AudioXpress issues (late 2011) I write something about the ALC0180-2300 module and how to implant it. Article includes an interview with the designer, Patrik Bostrom of Anaview. Anaview Sweden joint forces with Abletec. Abletec is responsible for the powersupply and Anaview for the class d amplifier itself.

PS. I have no commercial interest in abletec or Anaview. I am just a hobbiest like yourself.

Hi Wim,

I'm highly interested, especially because information is still very rare about these modules in the web. Do you know how late will be 'late 2011'?
I'm already very curious

The article was exceptet by Ed Dell in Mai this year.

As you maybe know is the AudioXpress magazine acquired by Elektor this summer, and the team of Circuit Cellar (also Elektor) is doing the editing now, I will write the editor tomorrow and see if they have a actual date of publishing.

I know I could have published it here, but feel AudioXpress needs 'reading stuff' otherwise they will not survive, and that would be a pitty. And I feel a hardcopy / magazine is to prefer over any publishing on the internet.

Enclosed 2 photos of my Abletec amplifier.
