Linear power supply for Weiss DAC 204

I agree, the U2 has a number of improvements over the Mini. I have not auditioned the U2. However, I don’t know if the improvement in overall sound quality is worth twice the price. This is wear I tend to look for a 30-40 percent improvement. In other words, a 20 percent improvement may be worth a $500 investment for a LPS. However, at twice the price for a U2, I would expect a 30-40 percent improvement. If not, I would consider a different streamer and increase the budget as needed. It’s simple not worth upgrading something if there isn’t a significant improvement in sound quality. I’m currently using a CJ Classic 62SE, ET3SE, and Lampizator Amber DAC. Nothing over the top but fairly revealing.

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.

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.
