Worthwhile budget measurement microphones for REW?

[Samazar]

Just realised that Cross Spectrum provides the 90 degree cal files which is what I need.

Absolutely. Here's a Comparison graph someone posted on another Forum a number of years ago.

That is good to know, thanks Wayne.

Just came to learn, CSL no longer calibrates or sells Dayton EMM-6 mics.

Is it possible to use REW exclusive (excel) JAVA drivers to measure multi-channel (7.1) in REW using the XLR Mic + Audio Interface loopback function?

Frankly I feel very dumb about what to expect from a better measurement microphone. My stereo is mid-fi, better than entry level. I have great imaging and soundstage.
I am using REW with a cheapest Dayton USB measurement mic the simplest way - run a sweep, make EQ, export EQ as convolution filter, that's it.
I really like the result, playing with REW made convolution filter is far superior to just plain Wasapi output, great project - thank you, it makes my life better!

My question is - will I get audibly better results from a better mic? Then, assuming a decent USB mic is about the same price compared to XLR one with audio interface (+/- few $) - do I benefit from getting an XLR mic and all its phantom powers, assuming my goal is just to build a better convolution filter? Please tell me like I'm 5.

No. Broadly speaking, a more expensive mic is likely to have better high frequency response before calibration and may have slightly lower noise floor. If your mic has a cal file then the first point doesn't apply, and mic noise floor won't be a factor in your room response measurements.

It turns out a cheap USB calibration mic actually does a better job here than a pro XLR mic. Two reasons:
A. You don’t need an audio interface, less hassle..
B. You save a few dollars for your evening lager ; p

USB calibration mics are best and easy to use... EMM-6, UMK-1 and UMK-2 are used by most everyone here...
And for fun here is a thread that compares the UMK-1 and UMK-2... https://www.avnirvana.com/threads/umik-1-vs-umik-2.8397/
