Are future improvements in Amp/PreAmps slowing to a crawl?

The answer to the question of this thread is, Yes!,  As a mater of fact,  the technology is going backward's with the invention of class D.                  However,  company's like Gryphon is pushing the technology of class A.                                           The fact you see class D is a money making scheme,  this is a very cheap implementation,  the profits are astounding to say the least,  Class A is extremely more expensive, the profit margin is far less unless you charge the amount of burying a cheap fix up and resale house!, the good ole day's of class A costing below $30,000 is over, I remember Krell, pass labs, Boulder,  Mark Levinson, Jeff Roland, etc...                              High end audio in general these day's is over priced. 

Let’s get serious for a second. High end amplifier manufacturers really need to do something about toxic transformer-generated magnetic fields (magnetic field countermeasures), directionality of all wire, not only the wire in transformers, but in fuses and the power cord. Also, they need to implement effective EMI/RFI countermeasures, damping for transformers, maybe decouple the transformers entirely, or put them outboard. Whose brilliant idea was it to bolt the things directly to the chassis, anyway? Not too swift. And those capacitors also, need to be damped. Hel-loo! So, the moral of this story: $90K Tenors or $200K Dart Zeels are off my Christmas shopping list until they solve those issues. You can’t just sweep this stuff under the carpet, folks. Hel-ooo! You can paint a turkey different colors but it’s still a turkey. 🦃

costco_emoji, good reaction! I assume you are enjoying another one of your DMT flashbacks. Obviously I’m not referring to transformers that are already outboard, Mr. Smarty Pants. I’m not surprised you didn’t know that all capacitors induce vibration in themselves. That’s why damping them is a good idea. I realize you’re a newbie and a wannabe but you shouldn’t let your emotions go crazy. As I said previously anyone who argues that air in a listening room moves at some great speed is not exactly in normal reality. If you wish to become the resident know it all I'd say you've already made it. 😀
