M14D 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, M14D este structurat în mod corespunzător cu optimizarea acesteia in 4Ω.
