New McIntosh amp build quality

I've been doing some research on the new MC 275 Mark VI. I've only heard the amp for a few minutes. I thought the 275 sounded nice. On another thread, a person stated the new Macs are not built as well as the older ones and in fact said the build was "shoddy" compared to pervious years. Just curious how owners of newer Mac amps feel about the build quality vs the old ones. Maybe a Mark V is a better option. I'm not looking for alternative brands...I have that info that is a mile long. Specifically the build (and sound) of new 275's (or new Mac amps in general) vs older versions. 

Thanks
