No it does not. the M2 has the typical MOSFET sound, similar to tube. The J2 has the typical JFET sound, if you know what I am talking about.

Please check my later post in this discussion. There are some limitations with the Class-A amps that you may want to think about.

What limitations are you talking about?  The biggest difference would be going with MOSFET or Power JFET.  

 

With the HE-6 and most of the First Watt amps, Class A or Class A/B really doesn't matter as the HE-6 will stay in Class A anyway because of the high bias in Class A.

 

Interesting to see your thoughts.

I should be careful here: the midrange of these amps are so smooth and free of the usual gunk you hear with most amps that, by comparison, they seem not to be as forward sounding. These amps almost seem to be too clean for the HE-6...
 

 

Strangely I am not finding that. The HE-9 which is pure A, at 9 watts has really amazing bass. The same with my Xindak speaker amplifier, which gives some 60 watts into class A. On the speaker amplifier yes, the bass is tighter, but still silly strong bass with the HE-6s. The HE-9 is more forward sounding, the Xindak has a huge soundstage putting the listener a few rows back. If anything both these amps are fantastic with the HE-6s. The same I could not say about the Ragnarok, which has lower class A bias.

 

Nothing too clean here, yet enormously satisfying. But again my present reference for clean & clear sound are the SR-009s.

I do understand the voltage end of it(JFET using the PN junction whereas MOSFET uses the isolated gate). I have heard fast transient  MOSFET amps and have limited experience with JFET, so I guess my question was posed as brand specific rather then  generalized (knowing you heard both).

 

I thank you for your answer!
