New Yamaha integrated amps

I'm not convinced the move to toroidal transformers is a good one. The best attribute of the current crop of Yamaha integrateds is the bass extension. It's my suspicion that some of that is attributable to the EI transformers. Of all the amps I've owned, those with EI transformers have consistently produced superior bass. It could be a meaningless correlation but the move to a toroid alone is not enough to warrant one of these new models over the outgoing series at closeout pricing. It's not as though the current models have a high noise floor, especially not in any practical/audible sense. 

Why would anyone buy a Yamaha amp when you can purchase a Parasound integrated.  I wonder why manufacturers promote watts when the real spec should be current?  Watts are a bigger number.

I switched from the original Parasound Halo Integrated to an A-S1100. The latter is a better sounding amp in most metrics, especially in terms of noise floor. It has also been more reliable. My H-int produced hum in the speakers that could be heard from 10' away -- my guess is due to a cheap toroid that didn't cope well with the 100mV of DC offset on my mains. That and I had to file a warranty claim for a faulty volume pot. The Yamahas sound very similar to a tube amp in the midrange. The Halo merely sounds like good SS.
