Douk Audio EQ5 Mini 5-Band EQ Preamp Stereo Analog Equalizer Portable Audio Processor for Home/Car

I got this to go between a Topping DAC and a little bear one headphones amp. The output from the Dac is a bit lacking in Bass and this sorts that out. Nice it doesn't inject any noise into the system. Overall a good buy.

Wanted to add a bit more bass and colour to my vynil. Put this inline before the main amp, and it makes a big difference. The pass through it great to show the difference or revert back to normal levels.It's perfect for my setup and the usb power means when the amp powers up it powers this pre amp also, so no need to turn it on and off. Perfect and great value.

The media could not be loaded. ...however VU indicators don't work in the one that I have received today. I've tried bluetooth connection with my smartphone, AUX to to RCA on my phone and bluetooth from my projector, none of the ababove brought VU indicators to live. The other think is the output quality. In the bypass mode is superior, but at the moment of switching into equalizer mode, quality drops significantly. I've got this device to enhance dialogues in Netflix movies, which it does and quality is acceptable as long as my shelf speakers are over 2 meters away from me. Overall I'm not happy with my choice.

I needed something to brighten the sound from a Brennan hard disc recorder connected to a Teac amp.The build quality is good and it gives me enough tonal control to really freshen up the sound.It doesn’t have the widest range, but very adequate for my needs and very good value for money.
