Once upon a time, reviews of Musical Fidelity components frequently filled pages in Stereophile. But in all my years covering audio shows, I can't recall blogging about any of the company's products, not even once. So, when my editor offered a review of the new M8xi ($6490), a hefty 101lb dual-mono integrated amplifier that includes a DAC, I seized the opportunity to fill a black hole in my consciousness. (Kindly cast aside thoughts that it would take more than a hunk of audio equipment to fill the black hole in my brain.) As long as I didn't break my back lifting the M8xi, solo, to the top shelf of my rackfor this I humbly beg assistance from spouses, neighbors, and friendsnew vistas were in store.
