iBasso DX320 MAX Ti
iBasso DX320 MAX Ti
The DX320 MAX TI from iBasso is a limited run music player, with only 888 units being released worldwide. It features the very best iBasso has to offer in a portable DAP music player including a premium Class A amplifier with a whopping 8.4V, x4 BD34301EKV ROHM DAC chips, and iBasso’s proprietary stepped attenuator, letting you use even the most sensitive IEMS for low volume listening.
It’s not the first MAX DAP iBasso has developed, but it’s certainly the best. The digital and analog sections of the DX320MAX are powered separately, with each having an independent charging system. The digital and analog hardware and signal communications, adopt optocouplers and I2C isolators to completely isolate the digital to analog sections from any interference.
The amp section outputs a beefy 8.4V – no voltage boost is used, which ensures the highest and cleanest current output. The Class A discrete amplifier circuit has less heat generation than the competition, while simultaneously retaining the desired signature and properties of a Class A amp – less distortion and maintaining the high-end sound quality in particular.
The World’s First DAP with a Stepped Attenuator
Compared with previous generation MAX series, one of the major improvements of the DX320 MAX TI is the replacement of the carbon film analog potentiometer, with the new stepped attenuator. This makes the DX320 MAX TI the world’s first portable music player with a balanced stepped attenuator (4 sections). The custom 4-wiper stepped attenuator has less than +/- 0.1dB channel tolerance imbalance with four settings for the physical gain control.
Android on Steroids
Like all iBasso DAP, the DX320 MAX TI uses Android, giving you all the functionality of a top-tier open-ended operating system. Equipped with a stunning 5.0-inch Full HD (1080 x 1920) IPS screen, the DX320 MAX TI has an On-Cell capacitive touch panel, resulting in hyper-responsive gestures and commands. The screens on iBasso DAP music players are some of the best in the audiophile industry. You can also dual boot to Mango OS in the DX320 MAX TI.
How does the DX320 MAX TI compare to the DX320?
The Max series from iBasso increases the power output of their music players, allowing the user to drive more demanding headphones. The MAX series also increases the chassis size and iBasso usually finishes them in full metal design. This might add to the overall weight of the music player, but considering the premium nature of the MAX series, the additional features are well worth it. The DX320 is still iBasso’s current flagship music player, but the MAX is built specifically for those who want additional power.
How does the DX320 MAX TI compare to the Edition X?
The Edition X of the DX320 music player is iBasso’s special edition DX320 to commemorate the 10th anniversary of the Android DAP and iBasso’s 16 years in the audiophile industry. It’s a limited run of only 500 units and is made from a liquid metal alloy, resulting in a sleek and futuristic design. The only difference between the DX320 MAX TI and the Edition X is the finish, as the specifications of the two are identical.
What is the difference of the DX320 MAX TI from the other MAX music players?
The analog potentiometers of DX220MAX and DX300MAX slide on the carbon film in the potentiometer with the resistance at different positions decreasing as you increase volume, which is used to attenuate the volume. Analog potentiometers solve the bit rate truncation problem in digital volume adjustment, retaining the full resolution of the recording. However, its design principle can present severe channel imbalance between the left and right channels at very low volumes. Also, the resistance tolerance of carbon film can be quite large, and often there is a+/-2dB uncontrollable volume imbalance between channels in the entire range and as the years of use increase, the carbon film wears, which may introduce a distortion to the sound when adjusting the volume.
What is a Stepped Attenuator?
One of the best ways to adjust volume in analog, is with stepped attenuators. The resistors iBasso chose are of very high precision, with low temperature drift, no thermal noise, and excellent audio performance. iBasso’s stepped attenuator utilizes a high-durability alloy contact to switch the internal discrete resistors mechanically. Our use of high-precision resistors keeps the difference between channels controlled to within +/-0.1dB. This is a massive improvement over +/-2dB of carbon film potentiometers. Moreover, there is no severe channel imbalance issue at very low listening volumes. In terms of sound, the stepped attenuator is very transparent, with accurate positioning and more precise imaging.
