Lumin upgrade
Hello:
I’m thinking about upgrading my Lumin U2 mini to the new Lumin U2, and would like your feedback.
My current front end is comprised of the Lumin U2 mini, powered by an SBooster LPS. It’s fed Qobuz via Ethernet from an optical cable coming from a Cisco switch, (converted to copper Ethernet just before the mini, using a cheap converter box with a Jameson LPS wall wart and a short Furutech CAT6 cable).
I’m using an Audioquest Coffee USB cable to feed a Benchmark DAC3 HGC, which runs balanced into a Benchmark AHB2 amplifier. The AHB2 draws current from a separate 20A power line, and uses Kimber cable speaker cables to drive a set of ATC SCM40s.
My listening space is about 16’ wide, with a 35’ length, and has basic treatments at first reflection points, on the ceiling above the listening position, as well as corner bass traps. I listen to pop, mid-later century rock, vocal and combo jazz, and some folky stuff too, usually at moderate (70-75 dB) levels.
My question is, will the upgrade to the Lumin U2 provide a substantial improvement to the sound (soundstage, smoothness, depth, etc), and, is my system resolving enough that I’ll be able to hear it? I do have mild tinnitus in my left ear, with commensurate HF loss, but most days my hearing is still quite reliable.
I was considering an Aurender as my next upgrade, but then saw the new U2 (with excellent price/trade-in for my U2 mini from a local dealer), so thus the questions.
Thanks to all in advance for any advice/opinions.

Happy New Year! After probably about 300 hours of running in the Lumin U2, I'm loving it. It's a solid performer, running with no issues. Pumping out the music in a very satisfying manner. There is more detail, more musicality, more presence, more 'depth' to the soundstage and dynamics. Overall, a very solid upgrade to my system. Not much else to say, other than that I'm demoing some XLR interconnects now. Enjoying the process. So much listening to do! Best, JAMES. |
@jimboman got my answer to the question on how you are connecting streamer to dac. So did the U2 opened up the top end a bit? It should be a nice step up in resolution from the Mini. |
@audphile1 Definitely opened up the top end. Feels like a lot more of the tracks have a holographic presentation, much more open than the U2 mini/Sbooster. Resolution is also greater. I'm enjoying hearing much deeper into the recordings. Of course, it's not always great. On one tune, (Black Crows, not something I usually listen to) I think I heard analog distortion, which I'd not heard before. Maybe it was something on my end, but it definitely wasn't something I heard before. Of course, I've compounded the degree of difficulty by testing some new XLR interconnects...heh heh. Oh yeah, and a pair of jumpers. The fun goes on! That said, I can 100% vouch that the Lumin U2 is a keeper in my system! |
Hey @audphile1 Congrats on your Aurender purchase! Fantastic piece. If I didn't have a lead on the Lumin U2, I was seriously considering the N200. It is amazing how much the source can improve one's system. Enjoy! JAMES. |
