D'Arbignal,
Okay, once again I believe I have mispresented myself, with the wrong terminology. When I said "warm" I didn't mean a sound that was altered or changed, such as you described with tube amps. I don't want a tube amp.
In my mind, I meant an amp and processor that delivers the closest possible sound, to what was intended by the recording engineer. A sound that does not color or enhance, but simply reads and delivers. As you stated in your post.
Sorry for the incorrect wording, and thank you for bearing with me on this.
Oh boy, I still have so much to learn.
