How important is a Linear Power Supply Versus a Switcyed one?

I recently purchased a used Sutherland Insight phono stage to replace the built in one in my Plinius8200 MK II integrates amp. I was amazed at the improvement in openness and presence. It comes with a switched power supply but there is an option for a Linear Supply for about 35% of what I paid for the Insight ($350). I have a Van den Hul One Special cartridge (if that matters). Is it worth it?

I took the plunge and am dealing directly with Ron Sutherland who assured me I will have no problem swapping the boards (which will save the back and forth shipping costs of $50 or so).

No soldering, and he is even willing to get on the phone in case I need any help. Nicest guy. I'll let the discussion know how easy it was and how much better it sounds.

 which seems a bit much compared to the cost difference when manufacturing the LPS board versus the SMP one.
Just the component $cost (not including enclosure) can be more than double for linear v smp.

I wonder what that represents in actual dollars. Double sounds high, but if its $20 versus $10, does that justify $350?

 $350 sound fair

Most of these small audio manufacturers have commensurate small volume. To that end, they are paying quite a bit for components, and an arm and a leg for assembly. What you can build 100,000 of for $10/each, can cost $100(or more)/each, to build 100.
