miniDSP UMIK-1 or UMIK-2

Sorry, I missed that, but as you have found out from @2234rew it is a high quality MCH converter. And now you are getting consistent and repeatable measurements with the timing intact. It does make an audible difference. (PS. I own an mk5 as well).

Well, I'm sure you missed it because you were busy with other stuff

But yes, the repeatability is something I didn't realize I was missing. Some of my filters would sound good, and some would sound worse with new measurments. I couldn't understand it out until now.

I've now taken a handful of measurements and every resulting filter, although graphing slightly different, sounds very good and similar to those of prior measurements.

It's a real eye opener.

Also, I still need to test the MK5 with playlists containing mixed sample rates, and make certain it switches properly between all rates. I've seen reviews on ASR where people have complained about slow switching.

What is connected to your Motu? Windows? macOS ? Linux streamer?

With MK5, after testing playlists with multiple sample rates I've found the switching to be a bit slow at times. Result is start of song has a very brief drop-off. Not too bad, but my other DACs play the same playlist without issue. Of course this can all be mitigated by having player software handle the sample rate conversion prior to sending to MK5.

This is with latest firmware and drivers.

If it starts to bother you, there's nothing stopping you from using your other multichannel DAC for playback.

The main thing is the 'best practise' for the measurement part (1 clock for ADC and DAC)

Yes, I consistently get better measurements with the MK5, but one thing that still happens and really bothers me is I'm still having the issue with spurious pops and clicks. And they can be loud!
I thought these had gone away with the new setup, but not the case.

Because I never encounter these pops and clicks with any other measurement software I use, I have to once again ask the question to @juicehifi ; Are you positive there is not something floating around in the Audiolense code base that could be root cause of this issue? These noises are a bit concerning at times.

I measure exclusively with the MOTU ASIO drivers, and they seem very stable.
