@brianbonf had mine for 1 month now and it is by some distance the best sonic upgrade to my system since I went digital 5 years ago. However, and this is an important caveat, I have an all Lumin front-end now, the P1 and U1 in separate rooms, the L2 serving up local files from its internal SSDs to both streamers via the network. The L2 is also the main ethernet switch for both streamers. The upshot is the maximum sonic benefit is derived from the L2 used as the hub of an all Lumin ecosystem. I make zero claims this is true for any other setup, which is not to say there wouldn’t be some sonic benefit, but I suspect the $4K L2 is only good value within a Lumin-based system.
Experience with Lumin L2?
Has anyone tried the LUMIN L2? The LUMIN L1 I've been using is starting to not cooperate and the L2 looks tempting with the SPDIF connections
