99% of the time in electronics "new and improved" means we found a way to make it 50% cheaper and added bling bling that cost 5% more so overall the company just saved/made 45% more than they would have with a good design / product and figures the extra profit will make up for the increase in rma's / warranty work that the cheaper parts they used internally and externally will cause.
And yeah I will keep my usa 100, 200 and 400 "wish I would not have sold my vlx400 years ago! man she was a brute, all 44" of her!
I predict that the older US amps will be a really hot item on
ebay as soon as the die hards see this new stuff!!!
