On Friday, February 28, 3–7pm, Audio Advisors, at 2271A Palm Beach Lakes Blvd., West Palm Beach, Florida, will present the new Wilson Audio Chronosonic XVX loudspeaker. Wilson's Peter McGrath will be there. Space is limited so please R.S.V.P. to Rudi, either by email rkothe@audioadvisors.com or phone, at (561) 478-3100.

The components I needed to choose for my first system were never in doubt: a turntable or record changer, an integrated amplifier, and a speaker. One of each, please, in those mono days.

Today, even in stereo, that trinity would be regarded as rather traditional—or, if you prefer, purist. Digital has exploded the range of source options and loudspeaker options. Yet amplifiers have not changed much in how and what they do.
