Can do some discount on two SMPS500-CLA with +-25VDC if anyone is interested.
There was a spike in prices all over the world for electronic components, and hopefully, we get a better price by next year.
However, the price you pay for my products is for the quality of the components used and the technical support over time.
Thanks!

I can say from my experience after buying hundreds of SMPS’s from MicroAudio, that Sami’s power supplies are made with very high quality components and the customer service and support is quick, friendly and superb.
I have built an M2X with meanwell smps
I just finished casing up X's LuFo Lite which uses a VICOR smps - these are built like tanks and have their own heatsinking
both sound great , the M2X has been pretty much working daily for the past 3 years ( and it runs hot )
Don't the SMPS emit any EMI especially placed so close to the amp boards?
My approach for Lazy Singing Bush which worked very well (very quiet) was to place the SMPS in its own chassis and then place the SMPS box about 0.5m from amp chassis. DC output wires from SMPS board goes via a few windings on a ferrite ring to reduce HF noise (according to Connex data sheet). Also the filtered mains connection was according to Connex data sheet. It is good to ensure you don't get HF-noise back into the mains which could pollute rest of the system. Then in amp chassis a heavy LC filter is placed. L is a serial DC-choke and C a large cap. Then audio gnd is on the cap terminal. There will be no pulsing currents on that cap. It was a "no-go" to have the SMPS inside the amp chassis. For future builds the two-chassis solution is the only way for me 🙂

Just today a member posted photos of his FirstWatt F6 (Class A amplifier) using a pair of 200W switchmode supplies inside the amp chassis. Have a look at Post #7,045 . It's pretty nice!
