In response to numerous requests from audiophiles, we have deeply collaborated with a Bluetooth manufacturer to co-develop and specially launch a limited edition tube amplifier with a built-in Bluetooth decoder board. This decoder board features independent power supply to eliminate power interference. It supports Bluetooth 5.0 for lossless transmission, lossless decoding (including FLAC, APE, etc.) in USB/TF card mode, AUX (direct audio cable input), and multiple sound effect adjustments. It offers extremely high resolution, outstanding sound quality, and convenient use. Highly recommended!
In response to numerous requests from audiophiles, we now present the Compact Handle Edition 6P1 (Limited Edition), which includes a Bluetooth decoder board.
In response to numerous requests from audiophiles, we now present the 6P1 Dual Meter Premium Edition (Limited Edition), aesthetically pleasing, grand, and very beautiful!
Effective today, the side wood panels are upgraded free of charge to rectangular straight panels. The front and back surfaces are finished with high-gloss environmentally friendly varnish, and the cut edges are treated with wood wax oil. This provides a better feel and more distinct lines! Product photos will not be updated separately. Please be informed!
"Tube" refers to the vacuum tube. What people commonly call a "tube amplifier" refers to an amplifier using vacuum tubes, etc. Some tubes are used for amplification, others for tonal enhancement. Tube amplifiers have their unique "tube sound" – warm, easy-listening, with good musicality and atmosphere. Tube amplifiers are the evergreen tree in the audio industry, ancient yet enduring. Their notable advantages are sweet, soft, natural, and intimate sound, especially their large dynamic range and excellent linearity, which are hard to replace with other components.
Characteristics of this unit: The sound features transparent highs, rounded mids, and soft, natural, bass with ample charm.
The transformers used in the kit are all oxygen-free copper (OFC) transformers. The silicon steel sheets are brand-new WISCO special-grade single-crystal steel sheets, resulting in transparent and elegant sound. The coupling capacitors are German Red WIMA audiophile capacitors.
(Friendly reminder: The chassis is DIY with many holes and numerous processes, so minor scratches or dents may occur during machining. Please do not purchase if you are concerned about this.)
The kit consists of separate components that require self-assembly and soldering to function. Please be aware of this.
