AIYIMA A07 TPA3255 2.0 Channel Power Amplifier 300Wx2 HiFi Class D Stereo Digital Audio Amplifiers Sound Amp For Passive Speaker Home Audio DIY with 32V Power Adapter

Product Information

The max driving power is similar, the background noise is absolutely dead silent with A07 PRO, while there is some minor noise if you really listen for it with TB10D. It embeds a TPA3255 amplifier chip capable of developing a large power of 2x225W under 4Ω, with high efficiency. Based on sound alone (overall tonal quality, detail, imaging, bass control…), the MP-D1 + A07 combination was superior. While this slight hiss doesn't involve any moving parts and isn't expected to result in wear and tear on the speakers, I prefer not to have my speakers "working" continuously, especially since they are the costliest among all the other components.

You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice.Model Five in particular has a large mid woofer driver, so they can reproduce bass if the source feeding them has the power. However we see Aiyima claim they use the same pot as the V3 on their MAX unit, yet refer to it as linear. Turning both wheels at absolute max can make the sound a bit too sharp and boomy, so around 3-4 o’clock is the sweet spot with the AIYIMA A07 PRO.

Interestingly, when you switch off the BT20A Pro amplifier, the volume controls on the pre-out are bypassed as well. You can avoid this by turning both wheels at max, this does not add any kind of distortion or problems, and the experience is super pleasing.Such is the case for users who pair the unit with a Fosi M-03 or an Aiyima A3001 sub amp to power passive subs or control active subs. We listened to more songs than those named in this playlist, but those are excellent for identifying a sonic signature. I thought I'd have to daisy chain from amp to sub to speakers, but instead, I can use the much tidier amp to speakers + amp (aux) to sub.

TI's ultra-low distortion high-definition high-power power amplifier power amplifier chip TPA3255 is used, and 5 NE5532 OP amps are used internally.Couple of things which you might have noticed but must have missed mentioning is the wobble of the volume knob and when idle if you lower or increase the volume you will hear a faint crackling hiss if you listen closely while being near the speakers. This is indeed great as a DAC and streamer but it doesn't have tone controls so there is no preamp controls in it.
