I've listened to the 6300. I live near Binghamton, NY. I also owned a 6900 for about
a year. The 6300 was disappointing. Very sterile, I thought. It also has a wimpy headphone
section. It had trouble driving AKG 701s. Actually not so sure
what "made in the U.S.A." really means in the case of the 6300. Sorry to be so negative.
I think that for $3000 (or whatever the probably only slightly discounted price would be) you could do
way better!
All McIntosh gear is made in the US at their factory. They do not outsource anything to the best of my knowledge.
No offense, but I don't think you really understand the McIntosh thing at all. There are a number of things out there that sound better than any given McIntosh at any given price point. (However the new mk.5 version of the MC275 is quite exceptional)
What you are buying with McIntosh is a product with a pedigree that is very well built, exquisitely finished and has a specific look, feel and functionality. It is also a product that keeps its resale value longer than any other piece of hifi gear on the planet.
Keep in mind I am not a dyed in the wool Mac owner, so I'm not sticking up for "my brand". McIntosh doesn't advertise in TONE either, so I'm not sticking up for that either....
The thing I have noticed about the Mac stuff is that it has a stately elegance about it and often has a lot more features and functionality. I have also spent a few years talking to a lot of McIntosh owners. They are fiercely loyal and honestly for the most part aren't audiophiles. The only other place I have ever seen this kind of product loyalty is with Harley Davidson motorcycles, which are by no stretch of the imagination the world's best (made, engineered, performing, etc) motorcycles, but people love them just the same.
Also, McIntosh is one of the few mfrs. in high end audio that can fix your 30 year old McIntosh product.
(the only other two I know of are Conrad-Johnson and Audio Research)
McIntosh is what it is and yes you can get more fidelity out of other pieces of gear for the same money, but it won't have the look, feel and ease of use that a McIntosh component. That's what their audience wants and they have been delivering it for 50 years. Whenever we have requested a McIntosh component, we usually have to wait a couple of months to get it, because every production run is sold out!
I guarantee you will never have a problem getting a piece of McIntosh gear in the living room past your wife either!
So in the end, there are different options for different reasons. If you want a killer integrated amp for $3000, check out the Predator from Valve Audio. It's amazing. If you want a pretty good amp that will look gorgeous in your living room, sound pretty good that you can hand down to your grandson and he will still be able to get $3000 bucks for it on Ebay 30 years from now, get the Mac.
It's just a matter of taste....
