"AMR is a company with capability and vision and this shows in the design and performance of the AM-77 - it's a thrilling amplifier that brings you the dynamics of valves with the power of transistors in a substantial but well-featured design."
- Offers a dynamic and revealing sound
- High build quality, input labelling and gain adjust
- Decent ancillaries
- Inconveniently heavy
- No preamp output
- Volume change is slow - a rotary control would have been nicer to use
