Description

Line Magnetic 218IA Integrated 3 + 3 wpc Amplifier. Plays my big Tannoys with ease.

Or use it as a premium Headphone player. EL84 power tubes known for musicality.

This unit comes with the original box and  manual I downloaded. Rated a 9 for

condition since used but no flaws anywhere. I bought it recently as an open box item.

No remote. Cute as a bug's ear.

Small and exquisite Mini218 IA tube amplifier

Mini218 IA tube amplifier is a mini tube amplifier launched by Zhuhai Lici Co., Ltd. This tube amplifier is designed with a concise concept as the starting point. The circuit is very simple. It adopts 2-stage amplification. The pre-stage and driving part adopt 12AX7, while the power amplifier stage adopts a 6BQ5 for single-ended amplification, and each channel outputs 3W Power. Such a low-power amplifier can guarantee a sweet sound, but the prerequisite is that it needs to be paired with a high-sensitivity speaker. In terms of function, Mini218 IA is equally simple, with only one high-level input, one headphone output, and two speaker cable interfaces with different output impedances of 4Ω and 8Ω.

 

 

The front panel of Mini218 IA tube amplifier has earphone, speaker channel switch, and volume adjustment knob, which is very simple

The back of the amplifier has two different output impedance terminals of 4Ω and 8Ω and a set of RCA interfaces.

The craftsmanship and quality of these connectors are quite good.

 

 

Is 3W output power enough?

Speaking of this, some people may ask: "The output power of the current composite audio is tens of watts. Is the output power of 3W enough?" Enough! Because in actual use, the listening distance is basically within 1 meter. The sensitivity of the Helium 410 speaker reaches 87dB, that is to say, when the power amplifier outputs 1W power, a sound pressure value of 87dB can be obtained within a distance of 1 meter. In actual listening, the sound pressure value usually rarely reaches 87dB. Therefore, although the actual output power of the power amplifier is not large, the output power of 3W is sufficient here.

As for the sense of hearing, what will happen? When I listened, the volume knob was basically adjusted to about half, and the program source was the high-rate Internet radio station in iTunes. At this time, the control of the power amplifier is very good, the sound is still very relaxed, and the image is very cohesive. Whether it is a violin or a piano, the outline of the instrument is quite clear, and it does not appear flat. It can be inferred that the output power of 3W is actually enough.

 

Exquisite, pure and natural mid and high frequency

The CD replay of a single instrument works well

After listening to it for many days, I like the sound of this combination more and more. Its sound is very pure and natural, especially in the mid-to-high range. The sound is particularly clear and pure, with a hint of aura, giving people the feeling of being very delicate and beautiful. In the album Debussy's "Children's World" performed by Arrau, the piano's sound is bright and sweet and soft, and the sound is smooth, the transition is natural, and the melody of the music is correctly reproduced. Listening to Ritchie's "Paganini Violin Sketch", the texture of the violin is soft and delicate, the middle and high pitch parts are soft and shiny, and the texture of the strings is vivid.

 

 

Summary: Line Magnetic Mini218 IA amplifier with Amphion Helium 410 bookshelf speakers can emit a delicate, sweet and natural sound with a good listening experience. Due to the small and exquisite appearance, these two products are one of the ideal objects to build a high-quality desktop Hi-Fi system.
