Sbooster with Lumin PSA

Perhaps this is already common knowledge but thought I'd share just in case...

Based on various posts I was considering adding an Sbooster LPS to my Lumin U2 Mini to see what improvements I'd hear.  

As part of my due diligence I emailed Lumin support with the following:

I've recently read about using the Sbooster LPS (https://www.sbooster.com/power-supplies) with U2 Mini and how it improves sound quality.

Is there a reasonable engineering based reason about the U2 Mini that this would be the case?

The response was short and to the point:

Hi,

This voids warranty.

Best regards,
Peter

So with a 2 year warranty I think I'll wait 18 more months before considering.
