Monitor Speaker pairing for Leben 300

Very happy with Proac 1SC for two years. Had Audio Note AN J earlier, not a monitor strictly speaking but also superb match. Swapped due to the foam surrounds (and wifie, they were black). 3,5x 5 meters room, all genres.

I recommend MMDecapo by Reference 3A

I have falcon LS3/5a speakers which are 15ohm - impedance works differently on valve amps..... I also used it / Tested it in my main rig with Tannoy Legacy Ardens (15 inch dual drive 93db and 8ohms) and it was nearly as good as my croft ATC combo.
