Got my FO last week. Thanks to Cristmass holidays I had plenty of time to assemble it.
I am using single SMPS1200A400 power supply to power both channels (cost savings, you know) and I had some concerns regarding ground loops as some members already reported problems with that setup. Well, output is dead silent when modules are not connected to any source.
Waited more than two days for my modules to burn in and just started some serious listening. Well, what can I tell... My Rotel RB-1070 goes to eBay.
I don't know where you guys are coming from, but this amp will find you wanting to listen all your recordings more and more...

Hi skp
Rotel is classic blameless topology, it is quite normal the First One outperforms it soundwise. I'm glad you like it, enjoy.

Hi all
This is a test. I have problems posting.
Will this make it?
just posted a long reply.. it seems the gremlins are active..
Sight.. the short version.;(
Lazy cat, can you make al list of the available or recommended parts on the first page of this thread?
Maybe even sell it as a complete First one kit?
I see lots of recommedations and i like to make a good decision about the components and where to order them. I noticed some development about a chassis.. what is the status?
You only take orders by email is supose? No shop or something till now?
This thread is very long and there's a lot of usefull info burried in the topics. An updated first post will shed some light i hope.

We've not really had any reports of issues and so I would suggest you try a full browser and clean of temporary files on your PC as problems there certainly do cause issues.

hi Seth-space,
The thread is a bit long (could be worse). If you do read/skip thru the thread, you will notice that:
The FO are ready made Modules (88 euro each)
There are recommendations on the Power Supply (Dual Hypex SMPS1200A400) (150euro each)
There is a custom made Chassis for sale (300 euro)
So there is a full kit... you "just" need to place your order (I can't say anything about stock or something).

But looking through the topic i see more modules in development

So our lazy cat has to clean up his shop a bit 😉
It's still hard to find all the components.
A simple website/blog or whatever would do the trick i guess.

Afford yourself two ready made First One modules and explore onwards.Thanks, helps a lot!

CIA, NSA, FBI 😀Seth, same thing happened to me.
Gremlins ? Moderators?!
your in a good holiday spirit 😉As much as you like![]()
But not really an answer i am afraid 😉
for a 2.1 system i need three?
Normally yes three modules but 2.1 system can be with passive or active speakers, sub could use two modules, so from three to ... modules. 🙄
