Can SMPS based preamps/amps sound organic ?

I was always a skeptic with SMPS all they way until I heard Soulution. Never heard the Rowlands but they are supposed to be real good. Raidho used them at a lot of demo's. Then they came out with the Aavik which they now use. Now Aavik just came out with a class A amp and pre but I don't know if they are using a SMPS. 

Given the positive and encouraging comments here with regard to SMPS  what explains the continued popularity  of linear power supplies?  It leads me to suspect that they must have some significant inherent justification. Or is it just stubbornness on behalf of many builders?

FWIW, my DEQX HDP-5 preamp/processor, which is their top-of-the-line model, uses a switching power supply. Their somewhat less expensive previous top-of-the-line model, the HDP-4, uses a linear supply.

I suspect that a factor in their decision to make that change may have been a need for additional internal real estate, because the newer model incorporates a touchscreen and some other functions that were not provided in the HDP-4. But in any event I have been very pleased with the unit’s transparency, absence of coloration, and total absence of noise at any volume setting.

Charles, regarding your question my guess is that contributing factors to the continued bias toward linear supplies that seems to be evident among many designers include their own familiarity with the use of those supplies, and perhaps also an expectation that many potential customers would be similarly biased.

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.
