Class A/Triode-based preamps


I notice that the Class A integrateds, preamps and other components I've owned are very "vivid."
What are the advantages/disadvantages of the two? Will a Class A component sound more musically real (a la concert hall) or more euphonic?

Atmasphere,
The owner`manual says signal path follows transformer volume to an input transformer to the 101D tube for gain then to the output transformer.
I'm curious. Is the volume control before or after the interstage transformer? Is the tube driving the transformer?
Atmasphere,
No doubt other factors matter it just seems that the combination of class A, DHT, transformer for interstage and volume control coupled with a large power supply gets the job done. This is the design of my Coincident Statement Linestage and I`m in music heaven as a result.

Triodes are the most linear form of amplification known. Class A operation is also the most linear. So it makes sense that a triode class A circuit will be better, but there are other considerations that affect the outcome!
Charles1dad,

I have been working with a buddy how built one and so far it is exceptional. We are now working on adding a transformer attenuator for it.
Hi
BigKidz your observations are spot on in my opinion regarding the absence of signal path capcitors. In my own experience it seems that designs that use DHT and an interstage transfomer in place of a capacitor do seem in general to be more pure and natural in sonic character, by this I mean less of an electronic/mechanical artifact that I now notice with the more common pentode tube/signal cap alternatives. I do realize there are exceptions to this personal observation.
It depends on the dsign implementation. Heated Triode gear is hard to implement but if the desings eliminate caps in the signal paths then I found most sound better then any other design wth caps in the signal path.
