La fel ca toate modelele din seria M,M20D este remarcabilă în orice detaliu, practicabil cu orice sistem de sunet de dimensiuni medii în care se așteaptă un amplificator eficient, compact și bine pus la punct a funcționa în mod fiabil pe o perioadă lungă de timp.Deoarece 2Ω, de obicei, nu este necesar în sistemele mai mici, M20D este structurat în mod corespunzător cu optimizarea acesteia in 4Ω.
