What customers say about "Key Specs"

Denon DA-300USB USB-DAC Silver

All inputs can handle all files up to 24-bit/192kHz and support both PCM and DSD files natively.
Easy-to-listen-to DAC offering detail and a good selection of inputs for the majority of setups.
The sound quality delivered from the DAC to the amplifier makes me happy - the sound is more transparent and dynamic.
I don’t know what the engineers put Denon in this box, but the vocals sound very natural.
This DAC proved to be excellent delivering excellent sound.

Woo Audio WA7 Fireflies Headphone Amplifier/DAC in Silver

Superlative dac amp combo. using it on a daily basis with my iMac.
Very good DAC. Can sate the power demands of almost any pair of headphones.
This Amp/DAC combo work well with AKG K812. Highly recommend.
The ESS Sabre DAC that Woo uses is a popular choice among portable music players and DACs. But this one have a spiky price.
If you’re looking at an amp to seriously drive IEMs in this price range, it’s probably a better idea to go with something that can match IEM-level impedance with switchable gain.

What customers say about "Size & Weight"

Denon DA-300USB USB-DAC Silver

A great little headphone amp that can do DSD. I love it!
Largely plastic construction, the DA-300USB feels solid and well made but still light and compact.
The universal shape of the case will allow him to find a place in any system.
The build quality is cheap and plastic. It's very light and clumsy.
Appearance of the device is not bad, but it's too light and in closer look it's it is seen cheap plastic.

Woo Audio WA7 Fireflies Headphone Amplifier/DAC in Silver

I loved the look. It's a light cube with really nice design.
Gorgeous from every angle of view. It's tiny device with glass top and looks amazing.
This cube-shaped amp really stands on its own, and its timeless compact appearance would fit into any era of technology.
It’s a smart and efficient design. Surprising lightness and strength.
Very healthy weight and clean lines through and through. Plugging in headphones doesn't push it around the desk. Very solid build.

What customers say about "Features"

Denon DA-300USB USB-DAC Silver

Connect to my marantz cd6005 with wed performance coaxial cable sounds fantastic.
Playing DSD files in my laptop it's excellent sound quality.
Build-wise, the OLED display is nice and makes the unit look upscale.
Very convenient to use, Hi-tech, DSD stream support, clear, juicy, detailed sound.
The unit have some lack of bass. For that price it might do better.

Woo Audio WA7 Fireflies Headphone Amplifier/DAC in Silver

Greatest audio for gaming paired with Sennheiser HD 700s to fix trash audio in games!
It uses vacuum tubes for its amplification and also has a built-in ESS Sabre DAC, so all you need is a USB cable to plug in any of yours devices.
One thing that always impresses me about the WA7 is its total silence when not playing back any music.
Clearly attention to detail was paid in getting the 1/8 and 1/4 ports matched in volume.
XLR output would've been a nice inclusion for audiophiles.
