Linear power supply for Weiss DAC 204

I struggle with assigning any kind of percent improvement to upgrades. I don’t know what 100% better sounds like as I just don’t have that baseline. 
I go as simple as are the improvements significant? Is what I’m hearing to my liking? Am I able to go back to the old setup and be happy? If not, is the improvement worth it to me? 
I suspect the power supply addition to the Mini will result in better sound - power supplies matter. But will it be a dramatic improvement? Probably not. Will going up to a better streamer give me more ROI? I would say yes. Also take into consideration the mods you will be making to the mini and the resale value.

So in my opinion it’s worth trying a better unit.  

Uptone Audio JS-2 Linear Poset Supply and it can power two devices.

I agree, it’s difficult to assign a number or percentage of improvement. I guess I look for the “wow” factor if I’m purchasing a new piece of equipment. In other words, is the difference in what I’m hearing worth the cost - ROI from a sonic perspective. 

I wouldn’t overthink this.  You’ve clearly heard significant benefits with your current LPS units so would spending double really get you that much more?  I don’t know but call me very skeptical.  I’d stick with Teddy Pardo, SBooster, or LHY as they’re all well-proven, high-value products where you really can’t go wrong.  Best of luck. 

I’m with @audphile1 

Teddy Pardo is the only company I have dealt with and I like the product and their service.

All the best.
