I can't believe I can have a contribution :-)
I listened to the OBX-R2 and OBX-RW at Living Voice headquarters in Long Eaton. Needless the attention they gave me was exquisite. So, I encourage anyone interested to give them a visit, very very good attention.
Now, coming back to the thread. I listened to the OBX-R2 and OBX-RW in a really big room with an upgraded Trafomatic Experience Two which is just 8Watts SET, and an Italian push-pull of 15Watts. Well, I much preferred the 8Watts Trafomatic and power was more than enough to go deaf if crancked to the maximum level. I was completely shocked 8Watts could have such a control of an speaker.
I repeat, the room was pretty big and the 8Watts of the Trafomatic were better than the 15Watts of the push-pull. It was for me a great learning experience.
