The K17 will get warmer than other devices for the following main reasons:
1.The K17 uses a linear power supply with good sound quality but low efficiency.
2.K17’s amplifier is OP + Buffer architecture, the front stage op-amp + rear amplifier transistor work in class AB. But in order to listen to the excellent, the static on-current intentionally set up a relatively large, so the static heat will be a little higher.
3.AKM flagship DAC AK4191+AK4499EX*2 belongs to the high-performance DAC so the heat is also a little higher than ordinary DACs.
4.With the appearance of the 4-sided heat sink design, K27can quickly form a full range of heat distribution. And it has the internal temperature protection circuit. So please don’t worry.
