Review: good quality product, sound quality brilliant, real value for the money.
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。

## Questions & Answers

**Q: If I don't want treble or bass gain, how should I use the knob?**

A: If the output is phono yes, however, the unit doesn't come with Bluetooth.

This desktop tube pre/headamp is simply outstanding. For the $ a real bargain. Works great for both iem's(Low noise) and full size cans(Lots of power). Tube rolling is super easy. 12v power supply can be easily upgraded. Comes with a good rca cable. Let me tell you, sound this good used to cost a lot more.
