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.

JAMES

@jimboman I have the LUMIN U2 as well and I created a playlist for burn-in that had multiple sample rates; 16/44, 24/48, 24/88, 24/96, on up to DSD64, and I set it on repeat for a week.  I just wanted to recommend that to you.

Share your impressions if you try the different digital outputs.

I was using the LUMIN USB output with my Holo Audio DAC, but I’m using the AES output paired with my recently purchased MSB Discrete DAC as I don’t have the USB module.  The AES output sounds excellent, but I would like to demo the USB when I get the MSB USB module on loan.

@jimboman It sounds like you are on the right track!  I use Cardas Clear XLR interconnects and speaker cables, with Audioquest power cords.  I always preferred USB music playback because I could play the highest sample rates with my Holo Audio DAC, but my music files and Qobuz max out at 24/192 kHz and I don’t upsample.  I have one DSD64 music file, that’s the highest sample rate music file I own.  If you have an AES cable, then it’s a free demo for you.  
 

Have a Happy New Year!
