Introduction
Douk Audio L1 is a stereo amplifier with built-in voltage boost and amplification circuits, designed to boost the output of virtually any line level audio source (such as TV, video games, MP3 players, ipod, phone, tablet etc.) to max 20dB. L1 features its wide gain range, wide frequency response, excellent S/R and HiFi sound, to bump the output level of the audio devices which are with an inherently low level output so as to match other sources, or to allow the use of a longer cable run than normal between components.
Features
- Mutiple input/output interfaces: with 3.5mm AUX/stereo RCA/5-DIN inputs and stereo RCA/5-DIN outputs, can be compatible with most low-volume audio sources such as ipod, ipad, phone, TV, MP3 player, potable CD player, computer, video game etc., and boost their output to the level needed to drive amplifier or speakers.
- With built-in amplification and voltage boost circuit: adjustable gain to match better with different audio sources, support DC 5-24V wide input voltage that can share the power supply of amplifiers, while L1 can always work at a high voltage of 26V to provide ±12.5V high output amplitude and max 20dB high gain.
- Unique design and HiFi clear sound: double-side PCB design, NE5532P op amp with pluggable socket design, convenient to change other op amps to enjoy different sound and bring much DIY fun for audiophiles. High-qaulity sealed potentiometer, with wide frequency bandwidth and excellent dynamic response, the sound is smooth and natural, warm and delicate with ultra-low distortion.
- Mini size with exquisite appearance, compact and all-metal design for durability and shielding the electronics from electromagnetic interference with noise rejection. Perfect design in size and function, suitable for many scenarios to increase the output level, such as home stereo system, mixer or speaker setup, karaoke, audio recording, party, live stage event etc.
Warm tips

Long Lasting Scent
Scent: Bourbon Oak, Size: 16 Fl Oz (Pack of 2)
I've tried dozens of different brands of body washes and have had various objections.
This is the best by far in every metric.
First of all the scent. Bourbon & Oak.
I'm not convinced that it smells like bourbon OR oak. It's definitely a warm musky scent and I would say it tends more towards a creamy spice with a strong low note.
Longevity:
My job is about 50 percent physical throughout the day and I tend to shower only at night when I get home from work. This is the only body wash whose aroma not only lasts through the rest of the evening, but well into late morning the next day. I would even say that physical activity brings out a very smooth and subtle character. This is the first time I've ever been able to smell a body wash the next day. It was surprising and pleasant.
As for moisturizing, my skin feels smooth but without the oily residue that I typically associate with moisturizing products.
If a product lives up to my expectations I tend to leave a simple review and fair rating.
For products like this that exceed my expectations I try to leave a more detailed review that highlights its strengths.
I will most certainly continue to use this brand and experiment with the different scents available.
10/10 would recommend.

Please do NOT reship items like body soap that have been returned
Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1), Scent: Seagrass & Driftwood, Size: 32 Fl Oz (Pack of 1)
So I've purchased this twice now, I love the scent and I love how it lathers up, overall very happy with the produce so long as I get a product that wasn't previously returned. The 2nd order I received, it was clear that someone had replaced the soap in the bottle with some other kind of liquid and returned it and I got it. First off that has to be dangerous and hazardous.
As you can see from the pictures, something is wrong with this product.
The first product I got had a clean scent, was clearly a body soap liquid. The 2nd product I ordered was more water, smelled had virtually no scent at all. Unfortunately I had already poured it into my soap dispenser so it's now not returnable. PLEASE DO NOT SHIP OUT RETURNED ITEMS!! It's dangerous

Good soap
Size: 5.3 Ounce (Pack of 4)
It was so good that my friends took some for themselves. Without asking. Bastarts... good deal though, smells very nice! Especially that whisky one. The coarse texture makes for a great clean!
