Okay, so I've mostly been hanging my head in shame and not waiting to actually contribute to the conversation or admit ownership of it for how bad this thing tested, but seriously, my room's not *that* bad.
For a little context, I bought this particular Wavelet unit used because it theoretically filled all the functions (stereo preamp/DAC/active crossover) I was missing in my 2-channel build-out, and I was entertaining the idea of matching it with Legacy's iV series of Class D amps to ensure that my power-hungry KEFs got all the wattage they could handle. I had noted to Amir when I sent it that I had observed some channel weirdness in the brief time I had it in my setup, and levied my own complaint about the archaic and bizarre network configuration process for it. I wasn't surprised to see the same complaints crop up in the write-up. All that said, I'm a little heartbroken to see the results it produced, but the results are what they are, and it's pretty clear that even if the unit wasn't operationally wonky, the results are grossly underwhelming. I would also note the manual to be notably lacking some information about operating it for people who are buying it standalone rather than as part of one of their active speaker integrated packages. I would, however, caution readers that this unit was bought used, so I can't attest to the relative level of care and/or abuse it received before I owned it, or that might have been incurred in the shipping to me or to Amir.
It may or may not be of interest, but this particular unit did not leave the factory with a pre-load for any Legacy Audio speakers, but rather for a pair of Emerald Physics open baffle speakers (the precise model eludes me, but it's written on the bottom of the unit.) After I received it, I talked with Legacy's support staff, who suggested that while they could recalibrate it with a profile for my KEF Reference speakers, but it would probably not be necessary once I ran the room correction. IIRC, if I had opted to send it in for factory reconfig, there was no charge other than shipping for this work, even for my situation where it was bought secondhand. So, credit to Legacy Audio for customer service, at least in that regard.
Regardless, I don't see the Wavelet going back into my 2-channel stack, given the issues with it. Further, even if that weren't the case, any subjective opinions I might have about the adequacy of its audio quality have been poisoned with the objective knowledge of its inability to measure up to the other gear it's paired with. It does leave me with an extended process of figuring out what pieces I do need to bring in to replace that functionality, and how much more of a hit I'm going to take in my wallet to get there.
