Making good on a <A HREF="http://www.stereophile.com/news/11382/">promise</A&gt; made several months back, <A HREF="http://www.avantgarde-acoustic.com/">Avantgarde Acoustic</A> is moving into the retail realm. The company's German-made horn loudspeakers are the featured products at <A HREF="http://www.avantgardemusic.biz">Avantgarde Music & Cinema</A>, a new showroom at 27 West 24th Street, Suite 502 in Manhattan. The store is privately owned and operated by <A HREF="mailto:TheHornStore@aol.com">Bob Visintainer</A>, who emphasized that his business is "definitely Avantgarde focused" but also carries other brands of electronics and accessories.

Robert Deutsch says, "There <I>is</I> something special about SETs: a kind of midrange magic, a harmonic rightness that tends to elude other amplifier designs." But how to get more power from a single-ended triode design? In his review of the <A HREF="http://www.stereophile.com//amplificationreviews/687/">Air Tight ATM-211 monoblock power amplifier</A> RD discovers one answer.

Single-ended triode amplifiers (SETs) have a considerable following, but even their most devoted fans admit that its maximum power output is not among an SET's strengths. You'd be lucky to get an SET that puts out 7Wpc, and some (like those using the 45 tube) are closer to 2Wpc. Highly sensitive speakers (<I>eg</I>, horns) will tend to offset the power limitation, and SETs usually sound more powerful than their measurements indicate, but the laws of physics still apply: 2W is 2W, regardless of the kind of amplifier that produces it, and an amplifier's manner of clipping and recovery from overload take us only part of the way toward achieving greater volume.

The subject was horses' fannies.
