Wow some really great marketing hype. The writer should get the award this year. There is nothing really new in the amp's magical features. Almost everything mentions has been used before.
One thing I do, ike are the speaker terminals. The really last great ones I was were on the Sony STR6120, designed to be used with a supplied wrench to really lock them down. All metal no plastic and hardened steel so unlike screw terminals when tightened down they do not stretch and break.
The screw connecting of important connections such as the factors? How is this unique? Well, maybe to Yamaha, don't know. As for other connections, a goodly number of those Chinese produced boards and amps are using them including some very inexpensive stuff. If this is such a good idea, then maybe everyone who uses terminators on speakers cables sprouting it is better than a mechanical connection are wrong.
In the tube days thermal shock was an issue and why component isolation was sought. With ss I doubt it is a concern and one of the benefits espoused by the original users if toroid vs metal core transformers was the elimination of shock and vibration. You could feel transformer vibrations so it was real but I never felt any such thing with a toroid, though I admit, it is not something I got around feeling up too often.
The amp my be excellent, first class and worth every penny of the asking price and I hope it is so well accepted in the market it will convince Yamaha to continue down this path but they need to do something with the marketing side IMHO.
and the PL depicted in the post above certainly isn't great in terms of sound quality -- although it is OK).
ahh, I see -- indeed, I cannot guess how it sounds... although I imagine it is fully complementary, but I am sure it's polite.
