About The Product1. Prefer sound quality, seek reproduction, multi-operational serial thrust, A935 selects two operational amplifier sets (OPA2604AP+OPA2107) featuring good sound quality and large thrust provided by American famous BB, with superb effect, the small-sized distinct dual-power boosted circuit carefully researched by engineer upgrades the transparency of OPA2604 to the highest grade of amplification effect. Power is the key to producing good sound from the portable headphone amplifier, and A933 power supply adopts the complex and costly dual-power design. Among so many single-power headphone amplifiers available in the market, A933 high-quality high-current positive-negative power supply is absolutely considered as the "master grade". Through partitioning, headphone amplification is kept far away from the power supply to solve the possible electromagnetic interference caused by power boost. Ultra-small-sized audio filter capacitor array + LC type filter circuit reduce the system ripple to the minimum, providing clean and high transient power to the headphone amplification circuit. As a headphone amplifier with the strongest sound quality, A935 is featured by high SNR, delicate and transparent sound quality and large thrust. Headphone fans are often experienced that, although headphone is the nearest acoustic device to human ears, even the distance from common in-ear buds to the eardrum is only 1-2 cm, in most cases, the sound is heard to be obscure, as if the glass cannot be properly cleaned, it sounds a bit unclear, A933 will free you from this concern. 2. This product uses quadruplex potentiometer to regulate the volume, the power switch is provided by Japan ALPS, the power relay is provided by Japan NEC to offer dual protection on the output circuit, prevent impact sound and protect the headphone. Its power supply is added with the unique charging feature, which can charge other intelligent devices and output 1A current. 3. About burn-in: Our intended design effect is only achieved after burning-in the product for some time. For headphone and speaker: need to burn-in for 96 hours; for amplifier and other devices: need to burn-in for 24 hours, burn-in mode: select the continuous burn-in or the cumulative regular use.Advantages1. Upgraded sound quality: top sound quality, let time prove everything, make sound transparent, awaken music inspiration, the new design concept, more than imagination, three-partition isolation circuit, master power, two operational amplifier sets (OPA2604AP+OPA2107AP) provided by US Famous BB, treble/bass is felt to significantly upgrade one level after multi-operational serially connecting to the product, which is benefited from the internal +/-7.5V high voltage for greatly enhancing the thrust. 2. Details reproduction: The product can capture more details which are not the extra addition to product but the existing ones, because non-professional headphone amplifier often disposes such details. 3. Increased sound field: Anyone who doesn't use a good headphone amplifier may never better understand "sound field", it is a sense of presence, the sense of scene heard from a transductive headphone is different from that added to the product, it is worth noting that a good headphone amplifier deserves a good headset. 4. Backup cellphone power: The unique product design (cellphone charging) can be used as the backup power.

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.
