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 ( 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:


This voids warranty.

Best regards,

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





To use the Sbooster with my Lumin T2, I needed to open the case, disconnect the internal power supply, and cut a wire (although I supposed I could have desoldered it), then connect their PS to the motherboard. I presume the procedure would be the same for a U2 Mini.

Why on earth would Lumin honor a warranty after somebody permanently modified their device?

If you replaced your new car's transmission with an aftermarket transmission would you expect the car's manufacturer to respect your warranty?

Warranty realities aside- I wonder how the external power supply that Lumin makes for the higher end models compares to the more popular aftermarket offerings. I know they charge a higher price but has anyone compared it to the performance of those like SBooster and Teddy Pardo? Is it even configurable for use with the Mini?
