I own the MG-20 speakers and am very happy with them with the following: Spectral preamp, Gamut power amp, Esoteric X-03SE CD player, Nordost Heimdall. Decided to upgrade to Heimdall from Blue Heaven speaker cable for more warmth, giving up a tad upper end detail/speed. Decidedly better with all music forms over previoud VA Beethovens. Not planning on any improvements
