ARC Ref 5se inferior to LS28?

Cleeds you are talking about minor parts differences, not  different implementations/schematics.   In fact there is some differing opinion on which of the KT Tubes is best, is there not? In my opinion Tetro's or not the last word and sound quality anyway. You need to look  to the triode for ultimate fidelity.  Which ironically was developed far before the tetrode was. 

To restart,, Ls28 or Ref 5se?? Whats the better move- I would be going from my ls25mk2 pre and using a 400mk2 arc amp--thanks

shuberto - that is silly and shows you don't understand the scientific method

cleeds - I agree there are more potentially confounding variables - there usually are in economics, and that is why it is not a science

BUMP

No one had addressed the original question - a sonic comparison of the 5SE and the 28.
