Can SMPS based preamps/amps sound organic ?
Lately I have been reading about some well known companies who make amps and preamps based on switch mode (digital) power supply. Nagra, David Berning, Linn, Crayon Audio comes to mind. I have heard a couple of their products but I always seem to hear some kind of switching noise which comes through as "digital" sounding. The organic quality is somewhat robbed and replaced with some hash. I wonder if there are any designs using SMPS that can actually sound natural and organic ?
To me it seems mostly a matter of convenience to use SMPS but I would love to discuss.

Of course. SMPS actually has a lot of advantage, SMPS is basically a power regenerator. Go listen to the JBL LSR305/8, it’s an all digital design. SMPS, class D, digital crossover, DSP. It’s the greatest bargain in audio right now. The 3 series 5x305+310s simply destroys $1000 to $10,000+ audiophile setups. There are also bad SMPS designs too, eg: Benchmark. |
SMPS is basically a power regenerator. I'm sorry this is not a correct statement. You take in the AC & convert it to a high(ish) ripple DC & then feed that into a SMPS & you get a tightly regulated DC power supply. For a linear power supply you do exactly the same - You take in the AC & convert it to a high(ish) ripple DC & then feed that into a LPS & you get a tightly regulated DC power supply. So, if SMPS is a power regenerator then so is the LPS. A SMPS is a DC-DC converter (& so is the LPS). When you speak of a power regenerator then you take in the AC from the wall outlet, convert it to DC & convert it back to AC (say, like the PS Audio P300/P600/P1200 power regenerators). |

I think Benchmark Media can help with their explanation and demonstration of smps advantage against linear power supply. https://benchmarkmedia.com/blogs/application_notes/152143111-audio-myth-switching-power-supplies-are... |
