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.

That’s for the clarification. I’m going by what I learned in school a very long time ago. ;-)

Just another reason I rarely rely on specs and measurements. I trust my ears the most. Ive heard stuff that has great specs and measurements that I just don't care for. And others that look horrible on paper but sound great (at least to me). Visa versa too.

Personally I don't get the sense that anyone is suggesting that LPS suck. This thread is conveying that SMPS can sound every bit as good and that technically LPS is "primative" relatively speaking. There are multitudes of components with LPS that sound superb, in fact state of the art. 

Ralph,  
I am familiar with the very high sound quality of your products, are you suggesting that they'd sound even better if you could use SMPS rather than LPS?

Some times this whole game of primitive vs modern without the consideration of "sound" feels like a trap.

Jaybe, I repeat again - most of linear power supplies in power amps are unregulated.  I would bet that 100% of linear power supplies in class A  amps are unregulated.  Can you provide the link?  Sonore, you mentioned are 14W, unless I'm looking at wrong website.
