Low power system based on the efficiency of the ZUs, the 9 watts of the SE9 are more than enough in this room. I have not had a chance to do serious listening since setting up the Omens, first impressions are positive. Plenty of bass which was one of my main concerns. Still awaiting the arrival of the NFB-11, for now using the audio out of the airport express. I went with the NFB-11 due to its use of the ESS Sabre 9018 chip, this should improve the resolution substantially over the jitter prone audio out of the AE. Music can be streamed to both systems simultaniously, the difference between the two is quite dramatic to say the least.

From what I understand TS audio is the manufacturer, they rebrand them for Norh as well as the SE-18 and the Norh pre-amp. I have been searching for TS's contact info for a while just incase I need parts someday, Norh has ignored my request unfortunately.


Thanks! I have yet to hear a single ended 300b, it will likely be my next tube amp though. I will have to give the ZUs time to break in, they are fun little speakers though. Two completely different sounding set ups, if I had to choose one to keep right now it would be the 1.6s. Time will tell if my opinion stays the same...
