Lumin U1 vs Lumin U1 mini + sbooster?

What I am talking about is not my belief I am simply reporting real world findings of audiophiles that have compared DI20HE + pi to DCS and that have compared DCS to full U1. So its not my personal belief based on my theoretical understanding. Its real world experience from other audiophiles.
I am not saying that I personally observed that. If I tested it myself I may disagree or agree with them. But given their findings I am content with my solution and their impressions are enough for me to be satisfied that going full U1 would not be worth it.
To re-iterate (because it seems you did not read/understand my post)... they found that:

DI20HE + Pi > DCS Bridge
DCS Bridge > full size u1
Feel free to read audiophile style or head fi if you doubt what I am saying ABOUT THEIR EXPERIENCES.

One other anecdote is from Steven Huang of audiosensibility who finds that sbooster + u1 mini is about 80% of the performance of full U1. So taken all the above its not a far stretch of the imagination that a better ext PSU + di20he in the chain would be on par or likely out perform full u1.

@stray

With your system probably the smartest thing to do is just add DI20HE. And down the road ext morion clock is an option. Sonore is already a great streamer. Going to full DCS bridge or even u1 mini probably not worth it based on everything I've said above.

Thanks for the thorough explanation. I did understand your initial post.

The difference between our takes is that I have had first hand experience with both U1 and U1 Mini+ S Booster and shared my experience on the perceived differences between the two, you on the other hand are assuming, based on real world findings of other people, that the DI20HE plus a streamer out performs the U1 and even the dCS Bridge. I’m happy that you’re content with your solution, but realistically you don’t know if it’s better than the stand-alone U1. You’re just assuming it is, based on what you read.

I read other people’s impressions/reviews and experiences to use it as a guide to improve my system but I make a conscious effort to not claim anything based on other people’s experiences, until I try it myself.

Again I compared both the U1 and U1 Mini + S Booster myself.

I concede totally that I am relying on other peoples impressions. But what are you using to evaluate the DI20HE? You are not even using other peoples impressions. You are just using theory about how it 'should sound'. Also you have never tried u1 mini with any other PSU besides sbooster... so people looking at the ext psu option should be made aware that doing this may be something to explore... they shouldn't simply conclude that welp sbooster is the end of the line.
