The big picture is reproduction of musical performance. Circuit design of amps is but one part of what we are all seeking from a process of recording, distributing and re-producing of these.

And your missing the point. The use of tubes is to INDUCE distortion in order to gain the euphonic qualities (to use Tyll's terms) of the smoother roll off of a vaccum tube. The whole attraction to tube is the second harmonic distortion it creates which gives it musical nature. Then by tube rolling, you can control somewhat how much "fuzz" you want inthe signal depending your likes and dislikes. |
No, the point is that trying to increase "musicality" is an attempt to regain some of the qualities of real instruments and performances that are altered or lost with ss amps (at least many of them). While this may get called "euphonics" implying you are seeking not accuracy but your favorite flavor of sound, the term can mean, more respectfully, seeking to reproduce the experience in the listener of hearing live performance which, it seems to me, is a valid aspect of the overall enterprise of music reproduction.

I'm not saying this is bad, I'm just saying that the "hybrid" approach doesn't seem to me combine the best of both worlds. If your using a tube for let's say the power supply, so freak'n what, what does that do for you? Your still SS when it comes to the audio signal.
If the output stage uses tube, to me, its a tube amp regardless of whether transistors are used for power supply or voltage gain.
The reason why I said it was "marketecture" was I don't see the inherit advantage of using a tubed based circuit in the input stage or for other secondary functions (for lack of jargon).
Can someone please explain to me HOW a "hybrid" amp is the best of both worlds? Inquiring minds would like to know. |
Of course, the question should be How could a hybrid amp possibly be the best of both worlds? You confuse the effort to achieve that called a "hybrid" with the question of how successful a given implementation is, that is whether it is a "good or successful hybrid" or an "unsuccessful hybrid". That is a good question that I wish those who know more than me would take up.
As to the Rudistor RP7 you have now gone back to calling it a ss amp, given that it has no tubes in the output stage, having just previously insisted it was a tube amp because it has tubes. Can't you see how pointless this is? If any combination of ss and tubes manages to improve musicality(in the sense I used above) without loss of definition and clarity, darkness of background, dynamics, etc., then it is successful and worthwhile as a hybrid IMO.
People hear music. They do not hear second harmonics, those only appear in the analysis and conceptualization of what they hear or put thru measurement devices. What are you interested in principally: music reproduction or circuit design per se?
