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

Yes, I have very efficient speakers (Zu Omen Defs at 101 db), so one would be all I need. However, two would really look good :)
I have pushed amps under harder conditions.   I have had to service two McIntosh amps, but both amps returned in stellar condition.  A big thank you to the "old man" who serviced the unit.    
I received my MC2152 about 10 days ago and the build quality is phenomenal.  I’ve upgraded to several different Mac products this year and every one has been flawless out of the box.  Yes I have read reports of others that have not been so lucky but my experience has been great.
I've had a MK IV, MK V and a MK VI in my system. All fabulous amps with equal build quality. 
Personally I preferred the MK IV, which I felt was just a little more tubey than the MK VI. I also liked that the MK IV had attenuators and looked like the 60's MC275's.
The MK VI does have a little bit of a different sound signature - more bass, more detail, but I guess I was so used to my MK IV that I kept it instead.
I bought all of mine used from private sellers with no issues what so ever. 
Only reason I sold it - I run my system as two channel and surround for at least 3-4 hours a night so I decided to go with solid state.
MC601's is what I have now and they're going nowhere. Had I have me room I would have kept the 275 for a secondary system in the future.
