The QP1R has 1.9 Vrms, this in high gain mode was good enough for me to enjoy the HiFiMan HE1000 at CanJam London.

The output level is 2.5 Vrms, the AK380s is 2.2 which is as I suspected, meaning the Opus will power more difficult to run IEMs and even the occasional full size. THD is how far away from the original input the output device is, the lower the better. Total harmonic distortion is 0.003% 1KHz, the 380 0.0008% a whole decimal point better. Crosstalk is the distortion occurring between the left and right channels as they are separated out from the original signal from the DAC. Signal to noise is a good indicator of how accurately the device is able to amplify the signal it receives without adding distortion.Д¬rosstalk is 130dB 1KHz Unbalanced the same as the 380. The signal to noise ratio is 114dB 1KHz, the 380 has a slightly better spec at 116dB, Unbalanced.

Great minds think alikeвЂ¦вЂ¦ but they donвЂ™t somehow sound alikeвЂ¦. Interestingly, the D1 Dacamp, which sounds entirely different from the Opus 2 to my ears вЂ“ has exactly the same ESS9018K2M Dual Dacs. The 3 chips mentioned here are expensive parts they are not found in smartphones, even the LG flagship with the B&O hifi add on steers clear of the 9018 and uses the 9028. There is no doubt in my mind that the quality of the DAC chip has a major part to play in the performance of a Digital player. So there we have it confusion! 2 DAC chips claiming to be the industry leaders вЂ“ yet the CS4398 has lower distortion and the ES9018 the highest dynamic range. This from the AKM people -вЂњlow-distortion technology achieves industryвЂ™s best performance of -112dB as a DAC with 120dB S/N characteristicвЂќ.

The AK380 uses dual AKM AK4490 32 bit DACs with a patented Velvet Sound architecture. QuestyleвЂ™s QP1R a single Cirrus Logic CS4398.

My iBasso DX100 has one ES9018 32Bit DAC Chip and was back then a rare implementation of this chip in a portable player. The specifications of the CS chip : 120 dB dynamic range -107 dB THD. The Audio Opus #1 Cirrus Logic CS4398 x 2EA Dual DACs in comparison. ESS Technologies describe the 9018 вЂ“ вЂњwith ESS patented 32-bit HyperstreamГ¤ DAC architecture and Time Domain Jitter Eliminator, the SABRE32 Reference Stereo DAC delivers an unprecedented DNR of up to 135dB and THD+N of вЂ“120dB, the industryвЂ™s highest performance level that will satisfy the most demanding audio enthusiasts.вЂќ TheBIT have put SABRE32 ES9018K2M x 2EA Dual DACs in the 2. As you know we are some of the most demanding ofВ audiences. This is a complex and time consuming process that demands a special working relationship between the hardware and software developers and a lengthy test lifecycle to ensure consumers get a robust and desirable product. The implementation of these components is down to the craftsmanship and attention to detail of the Research and Development Centre.

Start with a diesel engine and you will never become a Ferrari for example.

The quality of the DAC or DAC Chips used in the construction, play an important part in the signature characteristics of this player.

Volume Dial Lock on software would be nice.
