The 600W SMPS looks to be a good form factor to squeeze for dual mono in a small chassis... unless u put in those additional input buffers.

Perfect for Hypex NC500 amp in a dual mono solution ;-)

When are u going to start ops... can I join u? :)

Very soon  ;D
Waiting for the DAC that will arrive quickly and I start mounting.
What do you mean with "can I join u?" ?

I am still thinking whether to get Purifi or just get the NC400 diy kit. The latter needs only 30 min to assemble and hola you got a pair of top class D amp for less than 2k

the dual mono Purifi kit plus power supply will stay within 1.5k.
the tests i've read so far tend to say the Purifi goes one step further in sound quality

Well, today was the D-day :D
I'm just so happy, so amazed with the sound quality of that little amp! Simply wonderful. I finally can enjoy my speakers. Those are 1.1m tall hybrid transmission line, 3 way built with satori drivers. Powerful, precise, clear and always soft and musical.
On this piece of Musica Nuda, a remake of Roxanne (https://tidal.com/browse/track/4523610), live recoding of great quality, I can hear the fingers attacking the cords of the contrabasso and all the vibrations of the cords ! And her voice..........
Music is perfectly balanced. There is nothing too strong nor weak.
Details are well present but it doesn't become analytical. With the applause, I have the feeling people are in my room... Incredibly realistic

The amp is around 650€
The SMPS has not been released for sale yet. But should be somewhat cheaper than Hypex SMPS1200

How difficult is the DIY job, just wire up or soldering is required?

Congratulations!

I must say the Hypex SMPS1200 is no slouch, it is very very good.

I did a test recently, they have very Low EMI noise , can’t compare to linear PS, but not bad, mighty impressive



Here is me , everytime I power the speakers on with the Purifi 1ET400, absolute class.... it’s on a different league all together

For the price, absolute bang for buck

Here is the internal view of the Apollon 1ET400 for reference



Zoom in to the area circled, u will notice it’s twisted, this arrangement is good as it prevents the cable to function as an antenna , in short, the approach rejects EMI noise, when twisted



You will also notice, the internal wiring is very need and done appropriately, with good separation....




That’s the Apollon Purifi 1ET400 I’m using..

I’m using it for left, right, centre channel, pairing with this Divini PTY power cord, that also has extremely good RF rejection and EMI suppression without losing the liveliness



It’s fantastic , on an entirely different league compared to the rest of the pack

Extremely lively, lotsa energy on the highs, clear, good separation and details, and best of it all is the female vocals, they sound extremely sweet... very solid
