Has anyone had odd pops and crackles in the sound from their Zero (both headamp and preamp)? I've been burning the Zero in for around 12hrs a day since it arrived last week, without any problems until this afternoon. About an hour ago, I noticed some strange artifacts in the sound. These are...

Yes, it usually takes a couple of days for a tracking number to come through.

I was hoping it might emulate the pre-outs on the back when the headamp section is disabled, to enable connection to two separate amplifiers when the Zero is being used solely as a DAC. Alas, it would seem it doesn't seem to behave that way. Basically, I want to keep my LD MkIVse and MkV...

Has anyone tried using the headphone output in preamp mode as a second line out (to a second amp)? Connecting the headphone output to an amp does seem to yield a signal - but I'm not sure what signal path it's taking.

This surprises me. One would naturally expect a true inline UPS (with buck/boost) to have a "cleaning" effect on the power supply rather than a negative effect. Has anyone tried their audio kit being the only devices plugged into a UPS? (i.e. no other kit connected to the UPS)

I did promise an update when the MKIVse and MKV arrived. Both arrived yesterday in separate internal boxes, but bound together into one package. I guess combined weight was probably around 15kg with all the packaging involved. The package left Little Dot on the 15th, and it arrived here in...

Penchum, as someone with both the LD MKIVse and MKV, do you feel the OPA627 is still the best choice (383 pages later ) when using the Zero as a preamp for the LD amps?
