Best streamers WITHOUT a DAC

So, I fixed on the Lumin U1 Mini, which just arrived and was installed, replacing the Node 2i.  And the whole system is back up after repairing/recapping the preamp. 

The difference is NOT subtle.  I feared that it would be, or maybe not much difference at all.  The U1 is a transformation.  Most listening has been CD-quality upsampled to 24b/88khz (which seems to be a little better than the native stream). WOW. The improvements are mostly extremely low level detail - vocal inhalations, cymbal details, piano high register notes, that kind of stuff.  The Maggie ribbons are extremely revealing and seem to be getting what they deserve. Bass also benefited.  More controlled, better resolved.

In short, the U1 Mini uncovered things I simply hadn't heard before.  I was happy enough with the Node 2i, just felt that there was room for improvement.  I didn't know how much room!   $$$ well spent.  Now I have to re-listen to everything.

@daledeee1  SBooster makes an  adapter for Lumin that allows you to hook up a LPS.  I upgraded the power supply on my Node 2i and it made lots of improvement.  I used a PD Creative board.  They also make Power Supply improvement for U1 mini.. Might affect warranty.  Just food for thought.

Yeah, I'll certainly be doing the SBooster thing before long.  As for the rest, I'm quite satisfied with the Lumin at this point.  Obviously the Aurender stuff has a lot of very passionate advocates, but upgrading the SFD-2 just doesn't make sense as long as it works.  To be clear, it's the MKIII version which is vastly different from the others.  It also went back to Parts Connexion a few years ago for further and fancier upgrades.  Detail is mind boggling and it's not at all a weak link.  In fact, at this point I'm hard pressed to find any weak link in the system that wouldn't cost a fortune for only miniscule improvements, if any.  In any case, thanks to all.   The Lumin has greatly improved my life.

Next project:  retweaking speakers.  After fixing/recapping the preamp the bass was "fixed" too.  I'd forgotten what it originally sounded like.  That's all a topic for another thread.
