Hi, I’m intrigued by these amps, I am toying with the idea, always been a solid state person but have grown to appreciate texture in voices and the mid range in general. A couple of questions if you don’t mind, How old are they, what is the name of the model of the amp and what is the output at 8 ohms (OK that was 3 questions). I have some Quad 2912 and I’m wondering if the amps would be up to the job. Many thanks
