So on the 25th (Sunday), will it be available on the ibasso website for sale, or on Amazon?
This is what I'd like to know also. I had my DX90 stolen from my car a month & a half ago....to say that I am itching to pull the trigger on the DX150 is an understatement!

Subbed!!! :)

Snapdragon 425 processor? Now the HiBy R6 has some competition :)
(and boy is the Cayin i5 getting obsolete FAST)

I like the look of the side buttons and volume wheel. Looks sick.

1 micro SD card slot may turn some potential buyers off though. 400gb and 512gb cards still cost a hefty premium over the 200gb cards.

At 245g and DX200 size this is going to quite a big one to pocket lol. Rip jeans.

Why do you think so? It is 4 cores, not 8. I believe, the SoC is the same RK3368 as in DX200.

My only thing that is keeping me from buying the Cayin N5ii right now is that it seems to be having processor issues, with the device not being able to handle regular use due to only having 1gb of ram (freezing up,being slow, etc). I see Snapdragon 425 with 2gb ram on this and don't think I'd hae to worry about that. Gonna wait for user reviews on this before I make my decision.
Got misinformed

DX150 specifications:

OS: Android 6.0i9
CPU: 64bit 8 Cores A53
RAM: 2G LPDDR3
Rom: 32G eMMC
DAC: Dual AK4490EQ
Sample Rate: PCM:8kHz-384kHz(8/16/24/32bits) native DSD:DSD64/128/256
USB DAC Function: XMOS XU208, Thesycon USB driver.
WiFi/Bluetooth: 802.11(b/g/n/ac)(2.4Ghz/5Ghz),Bluetooth4.1.
Battery: 3.8V 4400mAh Li-polymer battery provided by MBELL.
Quick Charge: PD2.0, compatible with QC2.0.
Size: 128.5mm*69mm*19.5mm
Weight: 245g

Play time: approximately 10.5 hours when used with the DX150. This depends upon the resolution and current draw of monitors used. With higher resolution more CPU is used so the play time decreases. This is also true with higher demand monitors with more current draw.

AMP6 specifications and measurements with the DX150:

Specifications: (Measured with AMP6)

2.5mm Balanced Output:
Output Voltage: 4.8Vrms(without load) 3.7Vrms(32Ω load), 425mW THD+N<0.001%)
Frequency Response:10Hz-40KHz +/-0.5dB
THD+N:0.00028%,-111dB (without load @2.4Vrms)
0.00032%,-110dB (32Ω load @2.4Vrms)
Dynamic Range:118dB
S/N:118dB
Crosstalk:-119dB
3.5mm Single Ended Output:
Output Voltage:2.4Vrms(without load)
2.4Vrms(32Ω load), 185mW THD+N<0.001%)
Frequency Response:10Hz-40KHz +/-0.5dB
THD+N:0.0004%,-108dB (without load @1.2Vrms)
0.0004%,-108dB (32Ω load @1.2Vrms)
Dynamic Range:117dB

Crosstalk:-115dB
Line out:
Output Voltage:2.4Vrms
Frequency Response:10Hz-40KHz +/-0.5dB
THD+N:0.0004%,-108dB (without load @1.5Vrms)
Dynamic Range :118dB
S/N:117dB
Average Play Time: 10.5 hours with the DX150
The play time varies with different sample rate/bit rates, and headphone/IEM load.

Actually the RK3368 is an octa-core A53, not quad core. http://www.rk3368.com

I did some searching and the Snapdragon 425 is indeed using A53 cores too so perhaps that's where the misinformation stems from.

Yes. That's why I think DX150 has RK3368 and not Snapdragon 425 (which is 4 cores).
