  1. H***m

    Products are OK. Shipping quickly grew.

  2. L***u

    There is a bit of hiss comparing to my audio card.(The max volume hiss test). Tested with Meze 99Classics. Overall it is nice to be able to control the tone for the headphones, at the expense of the lost neutrality. Good product if you need an amplifier or you are curious about lamps in general. No connectivity issues, and nice sturdy build.

  3. D***n

    I pc-fi is being used. Tidy and high quality performance is no. So more neat sound source to enter the sound card the water you use. PC-soundcard (DAC)-nobsound preamp – headphone reason. This amplifier vacuum tube highlight push force is apparently giving strong. But small and delicate sound squish to Jim lot high input the sound is clearly not broken don’t other DAC grab bars body.

    The lamps are heated heavily, if completely embraced with three fingers for longer than 2 seconds-Burns. The body is metallic, heated noticeably but does not burn. Sound quality compared to the smashed soundhoods just the sky and the Earth! Details appeared. Who used to be far on the second plan. The driver did not swing did not put Windows 7 recognized itself without problems. Tested in ATH-M50x headphones. Packed well, in foam or something. Happy. Recommend!

  16. A***n

    This unity finally solved a long period of finding the correct solution with a proper impedance match with my active speakers. The audio quality surpasses all alternatives I have tried in the past. The unit does produce audible white noise. When audio is paused or at quiet moments it switches itself off with an audible mechanicals click. One of the tube looks misty/used but has no impact on the audio.

    Due to Covid19, shipment a little bit delayed. Finally arrived, tested ok. However, just notice, 6J5 tube being used is 7pin version. I have octal socket version 6J5 NOS, can not be used with this pre-amp. Perhaps anyone has further info?
