b4rr3l: I saw your post with photos of upgraded caps on connex smps. Can you describe the improvement after the caps upgrades ? I have similar smps powering my UCD180, so I would like to know. Thanks.

It provides a bit more dynamics and deeper bass, the base is quieter also with less noise.

Complete noob here, but I've been looking at this board for long enough to step into the world of diy audio.

Planning to put together this Hifimediy board plus the recommended Connexelectronic SMPS in a build similar to b4rr3l's.

But before I dive in, in all honesty how does it compare to a Topping TP22 ? If we are talking better by a noticeable margin, I will make the effort, no questions asked!

If I recall correctly, the TP22 is lower powererd, with just one output chip. Also, it is limited to a 24VDC supply. The Hifimediy amps have two output chips, and can operate on up to 32VDC, right?
Heh, I have one of each and have not directly compared them. Sorry.
I think I like the T2 more because I put it together. I do enjoy both of them daily and have no complaints.
