Default Comparison between SMPS and Linear Supply

So my friend just compared the mono NCORE I made for him with linear supply and another with SMPS. A 115 db system was used as speakers. 4 X 15 " in each speaker. There was no big difference between them. The one with linear supply was slightly
more " analog " and a little more attack with the SMPS. I was not there but I would prefer the one with analog supply from what I was told.

So what you are reporting is that the nc400 works better with the SMPS than with an analog supply? News at 11...

does not sound like that is what he said to me... the subjective impression of more "attack" could easily be an artifact caused by RF contamination of the signal by the SMPS; I am not saying it IS, but it could be.
More in depth analysis is clearly needed here to come to any conclusions, and a completye description of the linear supply in question might be helpful as well-of course there are all kinds of linear supplies which could be tested...

That s the problem with subjective descriptions. They can mean pretty much anything you want them to mean.

Very ugly holes at the back panels, but I don't care too much.
Any critic/suggestion about wiring is welcome.

Antonio,

Did the boxes come pre-drilled ??? The right chassis appears to have better wire placements than the left chassis. The power lines do not cross the signal lines and are further apart.

Very subjective. Also I suspect a preconceived bias: the linear supply sounded "analog" and the SMPS had more "attack," whatever that is. Now everyone else's bias is going to jump in with "analog, like in smoother, softer, more realistic, veiled..." and "attack as in digital nasty, etched, revealing, cleaner..."

Let's refrain. There are no conclusions here.

No not really . We will try at my place sometime. I have not heard it myself. What I wanted to tell was " no big difference " . For me that is positive for the SMPS.

"Analog, like loss of control, approximate, round in the edges", "digital, like accurate, controlled, honest"

Why wouldn´t it be the later that is preferred?

- Conclusions? -who ever said anything about that

Personally I just like it to sound "right"
