The DX120 is what we consider a pure music player. Optimized for the dac used, with power for most any headphone, and a size and weight that is total portability.

DX120 Specifications:

2.5mm Balanced
Output Voltage:3.6Vrms
Frequency Response:10Hz-45kHz+/-1dB
THD+N: 0.00028%,-111dB (without load)
0.00032%,-110dB(32Ω@2.4Vrms)
DNR:117dB
S/N:117dB
Crosstalk:-116dB

3.5mm Single Ended
Output Voltage:1.8Vrms
Frequency Response:10Hz-45kHz+/-1dB
THD+N: 0.00042%,-107dB (without load)
0.00056%,-105dB(32Ω@1.2Vrms)
DNR:115dB
S/N:115dB
Crosstalk:-115dB

Output impedance: Balanced - 0.38 ohms, Single Ended - slightly higher than 0.3 ohms.

16 hours of play time with standard files.

The DX120 development focused on obtaining the most out of the AK4495 DAC chip to deliver high fidelity at an extremely good price. The specifications for the AK4495 show a THD+N of 105dB. In real practice obtaining this THD+N can be very difficult. However our engineers, through hard work, using intelligent design and research, have reached a THD+N of -111dB. This surpasses the -105dB of the AK data sheet by 6dB! A mission impossible has been made possible. And you will enjoy the rewards of a high performance digital audio player.

USD 299

All the best Paul with your new product.

Will dx200 and dx150 also get the new mango os?
The DX150 doesn't have Mango. We are working on the FW for the DX200 and will see how it goes.

Holy Smokey the donkey...an SMD that has 1PPM stability ? And phase noises of -145db at 100kHz Or was it 1Khz ? @Paul - iBasso ?

Because I have not seen any oscilliator to disclose the phase noise at 100Khz (Offset), only 10Khz offset (max)

If it is 1PPM and as a TCXO with stability of -145Dbc/1KHZ. Then Holy-moly-freaking-Donkey!

Full Synchronize all in one board implementation with excellent clock ! Are you kidding me ? For such little device ?

Then, the price is to compete agains Sony WM300 ? Wow! Impressive ! This will take the market like a storm !!

Ok, I am officially unable to wait for Dx300! Gosh...If I could give you a critical 999 likes up! :D

^^ I want to be excited too...but first I would need to understand what the hell you're talking about :thinking:
First, just look at the clock performances, 30 picosecond and not 30 Femtosecond (notice 1 pico seconds equates to 1000 Femto second)

Phase noise, if -145db @100Khz, then it isn’t anything to write home about. But as I said, I never seen any clock to disclose this band, only upto 10Khz. So, even -145db for 10Khz, that is still hell lot impressive for such little clock. If it is -145db at 1Khz then it would be unbelievable because that is into the range of the expensive OCXO clocks

We need @Paul - iBasso to confirm the above phase noises information

humm.. I really dont know why people are so obsessed with phase noise, jitter and all the related stuff.
Lets talk about the analog stage. Is it possible to detail it a little more?

Regards!
