Speaker recommendations welcomed

If you go with Goldenear I would get Triton Reference just based on room size alone. Much bigger than the T66.

I'm always somewhat mystified by room size dictating speaker size. Do people sit 30 feet back from the speakers in large rooms? My listening space is in a large room with 18 foot ceilings, 20X30 feet or something, and I sit with my ears maybe 9 feet from the speakers in one end of the room. Efficient horns with 2 subs, and I rarely crank it up much except when I want the sound to bleed into the kitchen when cooking. I'm not an EDM freak having drunk dance parties (I admit drinking can lead to a volume increase, but I don't drink much). Get whatever speakers you like with whatever amp suits you, and the room won't care. One of my amps (Dennis Had tube SEP) fills this room with a massive 12 watts PC and the other is a Pass XA-25 with somewhat more power...doesn't matter...one bit.

I'm starting to move away from Goldenear (or any powered speaker Meridian,etc.) simply because I don't want to worry about an internal amplifier failing.  Not 100% eliminated but hesitant.
