Aune T1 USB Tube DAC+Amp Discussion Thread ***See first post for FAQ*** - Page 341

Story very simple. I got my first hdtv in 2000 so I went with hdtv00 14 years ago when I first started going online, well ok not first started to but when I settled in. Good times.

^^Nice to hear, I was a bit late jumping to the hdtv bandwagon :P

What country plug does the Aune come with stock. I'm trying to locate a ??? to Australian adapter.

I have a universal adapter here, but it is a little loose, I want something higher quality. 

Edit: Found the answer: UK plug.

Macbook pro right side usb port only plays in 16 bit mode, let's call it port A.

Change to left side usb port (port B), it works full 24. Use usb hub (ports C) and it also works with 24 bit support.

 

However the 16 bit mode in-between port A and ports B to C is quite different. I'm using a HD600 and I notice that port A the sound is more forward, the bass is punchier, in port B to C the sound is more neutral, cleaner.

 

Can anyone with a mac reproduce or confirm this effect? Thanks ;)

 

EDIT:

Connecting to port A the kernel reports:

"17/04/14 10:25:36,000 kernel[0]: USBF:    5704.586    There is not enough USB isochronous bandwidth to allow the device "DigiHug USB Audio" at location 0x14500000 to function in its current configuration (requested 582 bytes for endpoint 0x3 )"

 

- Port B through 3.0 USB hub does not play 24 bit, no kernel output.

- Port B through 2.0 USB hub plays 24 bit.

 

My hypothesis is that OSX kernel is rather strict when it comes to managing USB devices, each port should be able to play full 24bit. They are all USB 3.0 so with a couple of connected devices bandwidth shouldn't be an issue.

 

What may be happening is that the kernel is assigning isochronous support to at least one port when enumerating them at boot up. Further devices don't seem to be able to request this privilege, which is strange.

 

EDIT2:

In MIDI configurations setting 16 bit input allows the output to be set up to 24bit. Thread with science.

got to get the first batch ...should be here in few days 

Aune X1 Pro DAC / Headphone Amplifier 24bit/192 khz DSD 

 

 

Performance Specifications:

Full Name 
· X1 Pro 24BIT MINI USB DAC

Highlights:

X1 Pro 24bit mini USB DAC can be used as :
· High quality PC/USB soundcard/DAC
· High quality headphone amp
· high quality pre-amp

color
· Black

Size
·135*51*170(mm)

  Material and Special design
· New X shape appearance design with high-grade abrasive blasting surface.
· Laser carved panels , more refined and more wear-resistant.

Operator interface
· Two-color LED indicator display the current working status, it is easy for night operation.
·Concave button design , fit your fingers comfortably with less fatigue.
· Thread volume knob design , Comfortable and convenient.

Technology Design
Modular functional design , full expansion interface equipped.
External power adapter ,less interference.
3) Concave button design , fit your fingers more comfortable , two-color LED indicator display.
4) Modular functional design , full expansion interface.
5) High quality KOA, WIMA ,NICHICON components used.

Specifications:

Input SPIF×1 Coaxial*1 USB(1.0)×1 Analog RCA *1
Output Analog RCA*1 6.5mm headphone*1
Frequency 20HZ---20KHZ (+/-0.5dB)
THD + N <0.00227% (-92.8dB)@20khz Unweight 
Headphone output 0.05%
Input choose USB/SPDIF ×1 Analog/ digital ×1
Headphone output P-PMAX:10V
Headphone output impedance : 32 ohm---600 ohm
Line output 2Vrms
Power input DC12-18V 500mA
Size (chassis ) 135*51*170 (mm)

 

Now the X1MK2 has been upgraded to the Aune X1 "Pro" DAC: (Limited to only a few world wide for the first batch) 

Upgrades include USB section from PCM2707 to 24BIT TE7022, the entire USB section of the entire unit can reach to 24BIT which allows for pristine and uninterrupted performance. 

Aune X1 Pro functions :

1. 24BIT USB DAC function —this function is the upgrade of Pro version.

The unit adopts TE TE7022 to reach computer voice signal receiving sections.
Through the USB, interface receives the computer signal directly, using I2S output via the same as TI PCM1793 produced by DAC chip for decoding, and then to the Line Out or expander ear sound output.

2. 24bit/192K DAC:

The unit is provided with a coaxial ( Coaxial ) digital input. Using the ratio as low as 5PS WM8805 receiver chip, the coaxial line receives signal from the CD/DVD and the 24BIT player digital signal can be passed to the machine's DAC chip PCM1793 for decoding, like general CD/DVD turntable sound marked ascending, and can pass through the Line Out output connection to the external amplifiers or through the expander ear output to the headset to enjoy music. This machine is a super cost-effective 24BIT/192K scheme

3. Headphone AMP:

Ear expanding/Headphone section adopts OP+BUF frame line and can improve direct DAC transmissions, but also external larger equipment using Omron signal dedicated relay (Relay ) signal set change, by Line In ( RCA a ) input external analog signal (Analog ) such as CD/ DVD machine. Output, the existing DAC analog signal, and even an IPod sound output (requires adapter through the Lineout output signal )

4 . Pre-AMP:

This feature of Aune X1 Pro has special functionality and can independently volume levels. LINE IN to line OUT volume control, and may choose to DAC output volume controllable, all controlled by single chip microcomputer
