Review: マランツ７故障のため修理期間中のつなぎのために、安価なプリアンプをアマゾンで検索して見つけたのがこれ。 驚くべきことに、こんな安いのに良質な音がでてくるではありませんか！ マランツ７修理期間中の２ヶ月間くらい毎日聴きましたが、音の粗雑感を感じるところだけが非常に惜しいところ 6J1Pが互換球となるらしく、アマゾンでロシア製のを発見したため、これに交換したらものの見事に高品位な音になりました。 マランツ７修理完了後に聞き比べた結果、A1で行こうと決意し、いつの間にか２年経過しました。 生前整理している身であるし、次の故障考えたら面倒なのでマランツ７は売却しましたが全く後悔しておりません。 A1お使いの方で、若干の音の粗雑感を気にされる方は、ロシア製真空管 6J1Pを是非、お試しあれ。 フォノイコライザーも優秀で、私はもうこれで生涯行くつもりなんで、故障時のためにスペア用で追加購入しました。 信じられないくらい良質なプリアンプです。よほどのこだわりある方以外は、もう高級なのは不要だと私は思いますね。
Review: かなり良い音を鳴らしてくれます。 この安価帯のコンパクトな真空管プリをいくつか試しましたが、この製品が一番安定して音も良いです。 この価格帯でこの性能、品質は何も文句がありません。買って良かったです。

## Features

- Solves all acoustic challenges in residential environments: In the narrow urban living environments, the "difficulty of installing large audio equipment" and "noise leakage concerns at night" are serious issues A1 is compact in size (width 12 cm) yet, with a vacuum tube pre-amp, it reproduces even the subtle vibrato of records HD650 and other high-impedance headphones can also be driven, so you can enjoy live jazz performances with headphones even after your family goes to bed In addition, the low noise circuit design eliminates "buzzing" hum noise even in degraded power supply environments in apartments This is an ideal solution that achieves high sound quality even in rental housing
- Streamlining your sound sources: "Unifying" them into one: Living room records, bedroom smartphone music, and scattered devices can lead to complicated wiring and operational stress A1 has a rear input terminal that allows simultaneous connection of MM phono/Bluetooth receiver and CD player With the switch to change the sound source, you can seamlessly adapt to your lifestyle rhythm, such as streaming news podcasts on your smartphone in the morning and playing 70s rock on a turntable in the evening In the office, it can be connected to a PC and used to also clear up audio for web conferences Functions as a "Central Audio Hub" that reduces the management workload of multiple devices and smoothly integrates music with daily life
- Emotional effect of vacuum tubes for heart recovery: Not just high sound quality, but an experience where the heart is purified the more you listen is what modern people seek The harmonic components produced by the JAN GE5654 vacuum tube contain a rich frequency around 370Hz, a frequency proven to have a relaxing effect in neuroscience After a tiring day at home, listening to Bill Evans' piano will bring a "warm reverberation" that is different from metallic digital sounds, helping to regulate the autonomic nervous system Adjusting the tone to your preference using the knob is also important, for example, on a rainy day, you can customize the sound by increasing the bass by +2dB for an enveloping sound The act of listening to music itself is elevated to a healing therapy time
- Long-term reliability brought by master craftsmanship: The A1 is a durable design realized by a team of sound experts from Washington, developed over 5 years The CNC-machined aircraft aluminum casing is shock-resistant, and the vacuum tube sockets feature gold-plated terminals to prevent sound quality degradation due to oxidation A notable feature is the moisture-resistant coating applied to the circuit board, especially emphasizing stable operation in Japan's unique high-temperature and high-humidity environments Designed with a long-term vision of 10 years, it has gained support from those who prioritize sustainable consumption
- Create a "showy" living space with interior fusion: Meets the demand for "stylish rooms" among the younger generation, balancing functionality and aesthetic value The deep texture of the die-cast aluminum body harmonizes with MUJI furniture for a "gorgeous" accent on your desktop The special feature is the LED lighting effect, with the orange light creating a relaxing atmosphere for dinner time, and the cool green light creating a focused environment for work time Practically, by placing the headphone jack on the front, it eliminates the clutter of wires around the desk Designed to save space while also creating a display value as a "hobby space" when placed alongside a record player The aesthetic beauty that makes you want to share on social media creates a synergistic effect that enhances your motivation to continue your musical life

## Questions & Answers

小さいのに10万クラスのアンプと変わらず。アナログレコードプレーヤーに接続してヘッドフォンで聴いています。真空管のオレンジとミドリの発色を変えられる遊び心は、部屋の雰囲気やサウンドによって変える楽しみもあります。こんなに小さいのに優れもので気に入ってます。
