The use of transformer output coupling in the M3 allows the output power generated by the 5687 triodes to be fully utilised to drive the power amplifier and cabling. The second stage is again pure class A, single ended and is transformer coupled using a custom line level output transformer. Two 5687 dual triodes are used for both anode followers. The line stage is of a direct coupled cascaded anode follower type. Beyschlag resistors and Audio Note™ copper foil capacitors are used in the signal path. Final phono stage gain and buffering is provided by a further 6072, connected as an anode follower. The input stage of the phono board uses a cascode connected 6072 General Electric dual triode feeding a completely passive (zero feedback) RIAA EQ network. The phono input is directly routed to the phono board with AN-V pure silver Litz interlink. The volume and balance controls are Noble conductive plastic potentiometers and this output signal drives the line stage. Inputs are routed from Audio Note™ non magnetic RCA connectors into Swiss made ELMA gold contact input selector switch. Aside from the six key features on which the design is based, a technique called “Comparison by Contrast” is used to ensure that the product is developed with the most important specification of sound quality as the overriding factor. The development of the M3 Phono is the result of Audio Note’s ongoing research to find ways to make better audio products. We hope you will find the M3 Phono preamplifier to be a rewarding experience and a worthy investment. The highly refined circuitry, timeless engineering and careful hand assembly has resulted in a product of the highest long-term aesthetic and commercial value.
The M3’s design is based on the following six key technical features: We have developed the M3 using a “Comparison by Contrast” technique of aural evaluation - a system that is currently unique to Audio Note. The M3 Phono incorporates sophisticated yet simple vacuum tube circuitry to re-create the most accurate sound possible - uncoloured and realistic.
