If you are looking for a preamp that is equipped with high-quality vacuum tubes (6J1, to be exact) and built to last, you have found it. Douk Audio has made a preamp that’s going to last you a lifetime and, better than that, it’s going to run right out-of-the-box without any valve upgrades or changes required.

This preamp also features a universal power supply and an aluminum alloy shell that will keep the internal components safe. The input/output terminals are gold-plated to minimize noise and maximize sound quality, and it all comes complete with an ENIG surface finish for the PCB.

Classic Tubes

Finally, a preamp that you can purchase without having to instantly pull out the factory tubes and replace them with something that sounds good. This little preamp comes with classic 6J1 tubes that sound absolutely phenomenal. They also have an optimized circuit to provide a music experience that’s hard to beat.

If you so choose, you can replace the tubes, and Douk Audio has made this easy by clarifying that this preamp is suitable with:  6ж1П, 6AK5,6BC5, EF40, EF95, CV850, and 5654. While it’s unlikely you’ll be changing them, it’s worth noting that you have the option in case you’ve got a specific set in mind.

Beautiful Silence

Although the excellent tubes that Douk Audio has chosen to use in this preamp give it superb sound-quality, nothing beats the beautiful sound of pure, clean silence that reviewers have noted. “Mechanical noise is zero. Self noise is negligible.”

This means this preamp will not interfere or hinder your setup’s audio output in any way. All this preamp is going to do is add the clarity and tone you are looking for, and what more could you really ask for?

Customer Reviews

If there is one thing to be said about this unit, it’s that it simply outperforms all expectations. “I recently returned an ifi itube2, a $379 unit which was supposed to do what this unit does very well.” Reviewers are highly confident in this system’s intuitive design and superbly high-quality sound output.

“It has a definite high-end sound to it, that will reward you the better your source and the better your amp and speakers.” With this said, the biggest downside that reviewers can highlight is that the volume output sometimes tops out before reaching the final knotch. This seems to be related to the source input people are using.

However, most reviewers have not experienced this problem, so it’s hard to pinpoint whether it’s user error, an issue with the settings of certain input sources, or potentially a defective unit and these users don’t realize it.

This was only mentioned by a few people, so I am confident recommending it. Perhaps, if you notice this issue, do some troubleshooting and reach out to the manufacturer for assistance.

With all things considered, I really like this preamp! Just keep in mind “…it’s intended use is as a buffer between a source (cell phone, ipand, computer, etc) and the line input (or aux) on a amp or receiver.” Don’t purchase this as a regular preamp to drive your power amp. Although that may work, it’s not what this little unit is made for. With that said, it does what it’s supposed to do most excellently and you can expect it to run with superb sound quality straight out of the box.
