Many music fanciers are concerned about the background noise of vacuum tube headphone amplifier, but this product frees you from this concern, its performance in controlling background noise is extraordinary, the background is quiet after several tests and optimizations of the circuit design, without any current background noise, you will hear the purest, most natural, and most nostalgic sound. As to the testing of the current background noise: as it is known to all, the current background noise comes from two sources, one is the vacuum tube headphone amplifier, the other is the audio source or the audio cable (the audio cable makes it more likely to generate background noise), the correct procedure of testing the headphone amplifier is to disconnect the audio input cable, with power on, if the background of the headphone amplifier is quiet, it indicates that the headphone amplifier has a very high SNR. If unquiet, or this seriously affects you from listening music, it indicates that the headphone amplifier has a very low SNR. 4. Notes: An electronic interference device near the desktop may also affect the SNR. For example, if the vacuum tube power amplifier is placed near a wireless router or device, it may be interfered to some extent. Enclosed by an aluminum shell, miniaturized but exquisite, the front, rear panel is precisely processed by CNC machining center, you will get a terrific handle, the ultra-small volume will not occupy your desktop space too much.
