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?

Looking forward to hearing how it turns out.

Sorry didn’t read your entire post.
In your case sounds like the maker is saying the linear supply is better for this specific unit. Lower noise level I would expect. Low level Phono preamps do not require a lot of power but are most sensitive to noise. I would expect there would be specs that indicate noise levels in both cases for an upgrade of significant cost. Independent bench tests would be even better. A money back guarantee on the upgrade would also be nice. Or you can just trust them if they are a reputable vendor. Lower noise levels do typically result in better sound. More detail, better soundstage and better imaging.

Not very if both are done well.
