Douk Audio A5 Stereo Budget Amplifier Review
I'd thought that this EQ would be a regular device, so my expectations were low since there is little information and reviews about it. But, I was really surprised when I got it.
In short: This is a very good device. Robust and solid. It performs flawlessly.
It arrived well packaged as Douk Audio usually does. Delivery was fast!
In hand it feels sturdy, well made. Knobs are a bit small but are well aligned with a firm rotation and a dent at 12 o'clock where it's 0 db. Labeling is contrasty and clearly readable.
It is accompanied by a compact and good PSU 12V | 1,5A. RCA connectors are of good quality, They feel firm and are protected by a silicone cap (Nice touch!)
To my surprise, I'd believed that it would be small and plastic-lightweight, instead, it is large enough but compact, and is made of metal and weights more than expected (> 0,5 Kg).
Overall, a superb quality construction really, really affordable.
Regarding its performance, I use it on my working desktop setup right between the NS-10 valve preamp and U3 HP amp for improving the K612 output sound.
It does its job perfectly. I didn't notice any noise or coloration added when I plugged this EQ.
Correction of the sound firm of my headphones (lowering a bit the treble, boosting the mids and balancing the bass) was easy and straightforward.
All in all, a very good performer. It's a must for adapting the sound to your taste thus improving the experience of listening to music.
A real bang for the buck! Totally recommended.
Made my vintage Onkyo Integra 9100 open up and sound way better!! Worth the money!!
Excellent product. The features all work well. I have the TV plugged into it to process the EQ then into an amp and sub. Very pleased with the tone ranges and ease of use.
Easy to use .Easy to hook up.Functions as it should and sounfd better Twink thought it eould
Sounds great with Boyuu A2 tube amp and full range ( no tweeter no crossover ) bookshelf speaker. Balance control is nice.
