Double-sided A4 flyer for the SA-100, the tube/MOSFET hybrid power amplifier that Counterpoint shipped into Japan through distributor NOAH in June 1990 for ¥400,000. Counterpoint was a California hi-end company started by engineer Michael Elliott, active from 1978 to 1998 and specialising in exactly this type of hybrid topology: tubes in the input stages for “soul”, solid-state devices in the output for muscle. The face of the flyer shows the silver chassis with finned heatsinks and the line Handcrafted in California; the back gives a top-down view of the inside - toroidal transformer in the centre, two banks of output MOS-FETs on the sides - plus the full spec sheet: 100W BTL into 4 ohm, four 6DJ8/ECC88 tubes up front, output stage running without global feedback, copper-plated steel chassis, milled aluminium front panel 10mm thick.

| カウンターポイントに灯を入れる。ゆっくり温まっていく真空管とともに高まる期待と予感――。その先にあるのは、もはや「聴く」という言葉をはるかに超越した「体験」の次元、透明な音楽宇宙の只中にいるという圧倒的な感覚です。先鋭のステレオパワーアンプ、SA-100には、管球に現代的な命をふきこみ、ソリッドステート素子に音楽心を宿らせる独自のハイブリッドテクノロジーでなければ味わえない芳醇な世界があります。 | Light up the Counterpoint. Expectation and anticipation build along with the slowly warming vacuum tubes - and beyond them lies a dimension of "experience" that far transcends the word "listening", an overwhelming sense of being in the very midst of a transparent musical universe. The cutting-edge stereo power amplifier SA-100 holds a rich, mellow world that can be tasted only through its unique hybrid technology, which breathes modern life into tubes and a musical heart into solid-state devices. |
| 異なる要素のクリエイティブな統合、常識の再照射――。思えば、あらゆるイノベーションは、常にそうしたしなやかな思考を原動力にしてきたのではないでしょうか。カウンターポイント。1978年、マイケル・エリオットによって設立されたこの若きテクノロジー集団のアンプデザインには、そんなラジカルなエネルギーを感じることができます。音楽にとって最良の素子を選択し、それを生かす最適の方法を探求する――。そんな合理的なアプローチからごく素直に導かれたのが、真空管、ソリッドステートという性質を異にする素子のメリットのみを複合したハイブリッドテクノロジー。対位法を意味するその社名は、あたかも異なる旋律が優雅に併走しつつやがて調和していくかのような、そのアンプ設計のありかたを象徴しています。 | Creative integration of different elements, a re-illumination of common sense. Come to think of it, hasn't every innovation always been driven by just such flexible thinking? Counterpoint. In the amplifier designs of this young technology group, founded by Michael Elliott in 1978, one can feel exactly that radical energy. Choose the best elements for music and search for the optimal way to make use of them - the hybrid technology, which combines only the merits of elements of different natures, vacuum tubes and solid state, was derived quite naturally from such a rational approach. The company name, which means "counterpoint", symbolizes the way its amplifiers are designed, as though different melodies run gracefully side by side and in the end come into harmony. |
