G'day from Oz.
After seeing and hearing the M3 Sapphires on YouTube (New Record Day) back in about November last year, I became fascinated by open baffle speakers. When I saw the release of the M4 and M6 models late last year, I was determined to own a pair one day. Finally this month I was in a position to put things into motion.
After emailing Spatial a couple of weeks ago and getting no reply (this was straight after AXPONA), I found out that Spatial have a local retailer here in Australia. (Once again; they were previously sold here by a local store up until about 2019 i think.)
So, I placed my order this morning on a pair of white M4 Sapphires, and I'm told they will be in the first delivery here to Australia, arriving in a few weeks. I can hardly believe my luck; I thought I would be waiting months before I could get my hands on some! I have read so many of the comments here on this forum; thanks to you all. They have stoked my enthusiasm and made me sure this was going to be a sound decision.
I'll be driving them with an Audion Super Sterling KT150 (single ended; 25W). See the biggest picture on this page:

I'll add updates (and no doubt a few questions) once they arrive.
