Audio Research Reference M160 MKII

24.500

Mono tube power amplifiers from the actual Reference series of Audio Research. 2 x 140W / 8ohm, soundwise a real dream, very stable and built to the highest standards.

They can be operated in ultra-linear mode, which gives you the full 140 Watts of output power, or they can be run in triode mode, which gives you about half the power, approximately 75 watts per channel. Some people love the sound of triodes, and if you have efficient speakers, that might be an interesting way to go.

Including original boxes and manual. Newprice was 49.000 euro (pricelist available), now for 24.500 euro.

Improvements 160M MKII version:

“The sonic improvements are what you dream about, with greater clarity from top to bottom, even better transient speed, more vibrant dynamic contrasts, and iron-fisted bass. Recorded music, regardless of the source type, just sounds more real. The music gains a new sense of propulsion and movement, giving it a new sense of animation and life. We have taken a remarkable product and simply made it better.The icing on the cake is that the MKll improvements involve new parts and wiring”

Furthermore the MKII version features a newly designed cover grille and front plate, which allows the beautiful VU meters to stand out even more.
