Product Information:

High End Features at an Affordable Price

The Phono Box S3 B is a phono preamplifier that offers a fully balanced design in a neat, small package. Pro-Ject have packed this tiny chassis to the brim with high-end features. One of those is their new True Balanced Connection. When used in combination with a Pro-Ject turntable with a 5-pin balanced output and 5P to XLR cable, you can achieve a totally balanced connection, minimising noise and delivering a breathtaking analogue signal.

Until now, balanced connections were exclusive to the RS range of products. The Phono Box S3 B brings those features to more affordable products.

Fully Discrete and Symmetrical Gain Stage

The new Phono Box S3 B gain stage uses a fully discrete layout. A discrete circuit is composed of disparate electronic components, and individual devices. The amplifier section is built of single parts and doesn‘t use any integrated circuits! That makes for an extended and more costly design process but results in the best sound quality. The fully symmetrical gain stage can optimise the signal-to-noise ratios, feeding the semi-passive, RIAA equalisation stage with a clean signal to work on.

A foaming cleanser that doesn't dry out my skin!
Style: Tolerance Daily Foaming Facial Cleanser
I have very dry, reactive skin and initially looked past this face wash because it is foaming which is usually a no-go for my skin. I am pleasantly surprised with how well my skin tolerated this product. No dryness or irritation and my face felt clean. I also love that it is fragrance free because fragrances seem to really irritate my skin and who needs to smell their face wash? I am happy to say this is another great product from Avene!

Gentle cleanser for dry and sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser, Style: Tolerance Daily Foaming Facial Cleanser
I have dry and sensitive skin, and this cleanser has worked very well for me. It is very gentle on the skin and has not caused any irritation. The texture is light and foamy, it spreads easily across the face and rinses off without leaving any residue. After using it, my skin feels clean, soft, and comfortable, without any tightness. The size is quite large, which I find great because it lasts a long time with daily use. Overall, a simple but very pleasant cleanser for sensitive skin.

Gentle Yet Effective—Perfect for Redness and Sensitive Skin
I’ve been really impressed with this Anua Azelaic Acid serum—it’s one of those products that feels gentle but still delivers noticeable results. The formula is lightweight and absorbs quickly, leaving no sticky or heavy feeling behind, which makes it easy to layer with the rest of my skincare. What stands out most is how soothing it is. The 10% azelaic acid helps calm redness and irritation while still being mild enough for sensitive skin. Combined with multiple types of hyaluronic acid, it keeps my skin hydrated and balanced instead of dry or tight.  Over time, I noticed my skin tone looking more even and less inflamed, especially in areas prone to breakouts or redness. It’s a great option if you want something that targets multiple concerns—like texture, redness, and hydration—without being too harsh. Overall, this is a fantastic serum for anyone dealing with sensitive or reactive skin. It’s effective, easy to use, and feels like a high-quality addition to a daily routine. I’ll definitely keep repurchasing.

Totally worth it!!
So I have combination skin with a tendency toward closed comedones and I decided to try this product because I heard that azelaic acid helps with closed comedones. Honestly, I didn’t have very high expectations because my closed comedones have been very stubborn. I was already using the COSRX BHA before introducing this product, but it worked very slowly, so I wasn’t really getting the results I wanted from that product alone. Let me tell you that once I introduced this product, I finally started seeing the results I was looking for. I have noticed that my closed comedones have been resolving way faster than when I was only using the BHA and my skin also feels softer and overall looks healthier. I also want to mention that even though I don’t get inflamed breakouts very often, when I do get one, I feel like this product helps it calm down and go away much faster. I did start incorporating it slowly, and I highly recommend that anyone who wants to start using this product do the same and not rush into using it every day right away. Despite that, I personally haven’t had any issues with irritation at all and I actually find it very soothing, but you always need to be careful when adding new actives to your routine. I am currently using this product 4-5 days a week, once a day, and on the days I do not use it, I use my BHA instead. I also find that this product lasts a long time, since you only need like five drops for the entire face and the consistency is very watery. I’ve been using it for around two months, and there is still plenty left. Overall, I really recommend this product because it has helped me a lot, and while I am not sure if this alone would be enough to treat closed comedones, I would definitely say it is a great complement to other treatments.

Changed my skin in 5 days
This stuff transformed my skin in 5 days! I’ve had issues with random breakouts and redness ever since I turned 40 and have had difficulty finding a product that actually helps those issues. I incorporated this product into my daily routine for the last 5 days and my skin is clear, moisturized, super soft and redness/breakout free. I use this after washing my face and applying toner; I use just enough to cover my face as a little goes a long way. It has a very loose, almost oily consistency but spreads easily and doesn’t make your skin feel greasy at all. Once it’s absorbed into my skin, I apply my moisturizer. I would definitely recommend this to anyone with skin redness and dryness, it’s a game changer!
