Valve Heaven Review
If you are a fan of classic valve amplifiers and retro looks then feast your eyes on the new Audio Research Reference 160M monoblock. It features four KT150 output tubes with two 6H30 driver valves with both Ultralinear and Triode mode operation available. The former is said to give 150 Watts of output while the latter is rated at 75 Watts. If you are not a fan of KT150s, KT88s and KT120s can also be used thanks to the incorporated auto-bias circuit. The transparent faceplate allows a view of the glowing vacuum tubes while the power meter has LEDs to indicate just how loud you are playing your tracks.
