Hello, Couldn't find a dedicated thread about this power amp, so starting a new one here where I will be posting some thoughts, pics and some in-house pictures and measurements. Meanwhile, some details about this power amp taken directly from the manufacturer. Input impedance: 100 KOhms Frequency response: ± 1 dB 0 – 20Khz THD: <0.03% Output impedance: 1.5 Ohm @ 1 kHz Signal-to-Noise Ratio: 92.5dB Inputs: 2 X RCA (2V RMS line level) Outputs: 2 X Speaker Outputs Power/Impedance, Signal To Noise Ratio, Separation between the two channels: - 40W/4Ohm, 91db, 99% - 29W/8Ohm, 91db, 99% - 15.2W/16Ohm, 91db, 99% Power Supply 100-240V AC (12V 10A) Weight: app. 2.5Kg Dimensions: 210mm x 145mm x 45mm So it will fit perfectly inside a regular desktop computer. This should probably make it the first Class A/B power amplifier that perfectly fits inside a regular desktop computer...well, at least I'm not aware of any company building something like this before. I am considering this design and the small size a great advantage for gamers, audiophiles, but also for regular computer users that don't want to spend lot of money on power amplifiers that occupy lot of desk/room space. Enough power in such a small-size case was a huge challenge for BURSON, because most of power amplifiers that might fit inside a desktop computer are usually Class-D and not Class-A/B, so quite a challenge indeed (just saying, not willing to start a debate between amplifiers classes here). Like a good perfume, BANG is small, beautiful and strong, able to deliver enough power to drive our speakers inside our bedrooms and living rooms with a crisp and detailed audio quality. All we need is a volume-controlled audio source like PLAY or just a regular DAC with volume knob control and a good RCA-RCA interconnect cable or the Cable+ Pro. Per design simplicity, BANG has no volume knob, so please use an audio source with built-in volume control or a pre-amplifier between your audio source and BANG! Mains power supply delivers 12V/120VA which is more than enough for the "big" BANG. It's a low-noise SMPS (Switched-mode power supply) that can be easily replaced by the power source from inside your computer by directly connecting it to the existing "molex" connector. Power amplification is done by two reputable integrated circuits LM3886TF that do the job very well. There's plenty of musicality, crisp and detailed sound and the 4 power regulators inside are able to deliver about 5 AMPS per each of the 4 rails, so bass speed and attack will never be a problem for this amplifier. Inside pictures, details about the design and some in-house measurements will come soon. Meanwhile I am enjoying the weekend by listening my preferred music to BANG and my old PIONEER speakers.
