Texas Instruments headphone amplifier
TR-Amp headphone amp use Texas Instruments High Fidelity TPA6120 chip and allows music, not the amplifier, to be heard. TPA6120 current-feedback AB amplifier architecture delivers high bandwidth, extremely low noise, and up to 128dB of dynamic range.

Texas Instruments TPA6120 provides Superior Sound Quality with ultralow distortion and low noise.

Three key features make current-feedback amplifiers outstanding for audio. The first feature is the high slew rate that prevents odd order distortion anomalies. The second feature is current-on-demand at the output that enables the amplifier to respond quickly and linearly when necessary without risk of output distortion. When large amounts of output power are suddenly needed, the amplifier can respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise ratio. The third feature is the gain-independent frequency response that allows the full bandwidth of the amplifier to be used over a wide range of gain settings.

No Noise
Using a Super LOW ESR tantal capacitors, high grade components in power-supply design and 4 layer golden plated PCB technology from PC and smart phone industry we reduced the noise to minimum. This will improve super fine details especially in Hi-Res files where you can feel and hear the difference.

I also made both a video review, and a full written review for those curious!



And the written article!

Had to thumb a reviews just to verify the rear i/o.

EarMen TR-amp knob is very excited to see me i guess

Here's my review of it as well!

Needless to say, TR-Amp has become my go-to source, and has been my daily driver for at least the past 4 months. Seriously underrated!

 

[NA Blur]

I highly suggest you send one over to Amir at AudioScienceReviews to get it measured. He will give you invaluable feedback if there are any glaring issues which will help improve the product.

Looks awesome though!

Have not heard of this, and have not checked reviews yet,
But spec. wise, this is not impressive, strong competition are iFi Hip Dac, and FiiO Q3 all are lower priced.
But, of course, how it sounds is another story.

Personally I enjoy the inclusion of 6.5mm out and full size RCA outs. I also keep one next to my reading chair in my living room runs ETHER CX well!

You shoul try the TR-amp. The hip-dac actually crap. Lacks micro details and treble energy without any crispiness.
And you think 9038 flagship chip is not enough? or the driving power is not enough?

I have/had ES9038Q2M DAC, not portable, such as Burson Swing (still have it, with Opamp Vivid V6, it is great).
Topping Dx7s (dual ES9038Q2M). They are good, but ES9038 Pro is better.
Looking for portable Dac/Amp, for IEM, driving power is not that critical, I don't plan to use it for full size HP.

You definitely should go for the TR-amp. I compared it with the Hip-DAC and the ifi was bad, very bad (worse than HUD100 mk2). Lacking with the necessary stuff like details, transparency and energy.

I sent mine back. I was using mine as a portable amp utilizing an Ipad as a source. By the time I got a CCK and USB-C cords hooked up and then added IEM cables it just did not work for the space I used it in. I did like the sound and the 6.5 jack. The problem I did have was the volume control emitted audible static every time the volume was changed. Ultimately it went back and purchased a DAP which I found more versatile.
