Hey Bif, don't sweat it. The post above from Tsushima1 states that he ordered KT150's from Upscale and put them in his REF150 with no apparent issues. All is good.
You can not order KT150's from ARC because Kalvin will ask what amp you want to put those in and if you say a REF150 he'll tell you that the amp will blow up and take the house with it. You know why? Imagine each owner of a REF75-150-250-750 calling into ARC for matched pairs/quads/octets of KT150's. If they commission the use of the KT150's in those amps they will likely be "stuck" with a BIG stash of KT120's that no one would want and to make matters worst, most of their older amp models won't "sport" the use of the KT120. I don't think that ARC want people to trade their REF150 for the new GS 150. They just want to keep their little precious KT150's for that new GS series.
Having said all that, you can now call Kevin and get a matched set of Octet for your REF150, put them in and enjoy the music!!!! If you wait for ARC's blessing on the 150's the KT200 will be out.
