tordial wont matter much with this design because of the topology of it, its easy to eliminate noise. there's a reason why yamaha went with this old circlotron design. and anyways tordial transformers doesnt automatically mean it has higher noise floor. just look at how much great gear like pass labs uses tordials.
New Yamaha integrated amps
Just a few days ago I checked the Yamaha site to see if they really were releasing a new S lineup. I read somewhere (maybe Reddit or here) that they were going to release updated S series integrated amps. Well, I checked again tonight, and voila! There they are---the new A-S1200, 2200 and 3200 (flagship). I'm in the process of looking for a new integrated and the 2100 was on my radar. I'd like to see what's different on these. I bet the older models will have some sweet deals. Has anyone seen or heard them yet!
