Hi Zaibatsu,
I do not see an argument here about understanding circuit design/implementations between pure Class A, MX 1k or 10k.
Class A design not equal MX-1K sliding bias design and MX-1K sliding bias design not equal to MX-10k sliding bias design..Yes that is clear, never been in question, I read those articles..etc
Semantics, that is what this argument is about, so there you go:
The MX offers Class A LIKE performance.
Hope that clears out the air.
Same goes for M sounding the same with MX:
The M and MX have SIMILAR sound based on other accounts / opinions....Not mine, but yeah, I already mentioned that...
There, I amended my statements
wait...what?
I have a feeling you could get away with an M-60 pretty comfortably, and get the same sound as the M-80
As far as heatsink mass, hmm, you mean surface area?..
The MX fleamsy fins do an excellent job at dissipating heat for a sliding bias design. You need surface area, Mass is secondary in importance.
The M heatsinks certainly have greater mass, and possibly larger surface areas as well, one would need to measure and calculate, but are they located within a sheet metal box that is prohibitive to air circulation to some extent. That might be suitable for some circuits but is it suited for continuing use in Class A?
... as are the massive heatsink and the design of the BX-1 monoblocks,.... since you mentioned them
Yeah, discussion for a different thread, but the BX-1s are moving heat incredibly well. After hours of use they were very comfortable to the touch. I have a suspicion that whomever had their units baking themselves to death, had them in a place with poor ventilation.
As far as research and development for the mx-10k, what is wrong with that? A true engineering company is expected to do that for a flagship product. I wish more companies did that and I trully wish Yamaha would start doing it again.
As a consumer, I would take that overengeneerring (if there is ever such a thing) over pseudo original designs thrown in a 1inch thick front plate aluminum box and sold for many times more than the MX 10k or other true engineering statements.
But, yeah good discussion.... Sorry for diverging off the subject of the thread.
