It seems to me that my review of Monitor Audio's Silver 8 loudspeaker was published only a few months ago. Actually, it's been three years. The Silver 8 so impressed me that I bought three of them, along with two Silver 2 bookshelf speakers, for my multichannel system in Connecticut—and still greet them as the newcomers to my system. So installing and reviewing their successors, the 300, from the sixth generation of Monitor's Silver line, seemed very familiar.

The hoary question of tubes vs transistors, once certain and clear, is made ambiguous by recent products from a few solid-state specialists, not the least being Ayre Acoustics—the company that endures in the wake of the passing of its founder, the widely admired Charley Hansen. In their solid-state preamplifiers and amplifiers of the past decade in particular, Ayre has enshrined a number of technologies that are more than just variations on the audio-engineering status quo, and that appear to pay real sonic dividends.
