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.

Why to design complicated SMPS when the most of customers believe that it has to be big and heavy to sound good?  Small and efficient bring suspicion that something (sound) has to give.  In addition word "switching" suggests electrical noise.

Jaybe,
I'll check that site and read the commentary presented. If the prevailing argument centers around measurements and specifications that won't do it for me.  The bottom line criteria for me is what does it sound like?  Al,  I know you are a technical maven.  Yet I still  believe that you must be satisfied with the sound quality of an audio component before you'd place it  in your system.  I make that assumption based on your current system makeup. 
Charles, 
Charles, yes, as I’ve said in a number of past threads my belief is that specs and measurements can often be useful, but primarily because they can often make it possible to **rule out** components from consideration. In some cases by raising doubt (or worse) as to how suitable a component may be for use in conjunction with other system components. In some cases by raising doubt (or worse) with respect to how suitable a component may be with respect to user requirements (such as a desired maximum volume capability, for example). And in some cases because a spec or measurement that is **too** good (such as extremely low total harmonic distortion, for example) may create suspicion that something else has been compromised to achieve that (such as heavy-handed application of feedback).

But I’m certainly with you in considering sonics to be THE selection criterion once the list of candidates has been narrowed down as much as possible on the basis of specs and measurements, as well as on the basis of cost, physical configuration, manufacturer reputation for support, and other such factors.

Also, as you may have observed over the years, with a few exceptions I usually tend to avoid participating in threads involving ecclesiastical controversies about the superiority or inferiority of one design approach vs. another. Such as might arise with respect to switching vs. linear power supplies. The reason being, as I know you would agree, that what usually matters most is how well a chosen design approach is implemented, not which approach is chosen.

Al,
Without a doubt implementation and sheer designer talent are the major determinates of a product's  quality and performance. You are unquestionably wise in avoiding the endless non-productive squabbles that are all too common. I've backed off myself the past couple of years.
