Reference class phono preamplifier with unique continuously variable impedance control

This ultra low-noise and low-distortion preamplifier is truly made for the audio connoisseur. It offers not only breathtaking performance but is capable of adapting to virtually any phono cartridge through variable its impedance control. Impedance adjustment can even be done during playback! Due to the use of premium components, such as the SSM2019 from Analog Devices for the input stages and the Linear Technology LT1010 as its high current buffer stage, Phono Box RS delivers ultra low levels of distortion and noise. Its very low output impedance makes it insensitive to selection of interconnect cables and lengths.

A selector switch permits use of fully passive RIAA or DECCA equalisation. The Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. Vinyl playback has never sounded clearer, more detailed and smoother than with this superlative phono stage!

Switching back to Paula’s choice
While I like the all natural ingredients, I switched back to Paula’s Choice instead. In my opinion, I think it works better.

The Best Clean Beauty Facial Sun Screen!
This spring I tried four different clean beauty facial sunscreens. This is my favorite. First, it goes on with a light tint that rubs in, which moisturizers and becomes a primer for my bare minerals powder foundation makeup. Absolutely no flacking after applying the powder. (Many times if I am just out walking, playing pickleball or working in my garden I just wear this and skip the makeup) Second, the scent is so nice and light. Third, and actually most importantly is the rating on Yuka of excellent and that it works very well in the sun. I have worked hard to find only clean beauty products for my skin and I so appreciate of companies that provide them at an affordable price. I highly recommend this sunscreen.

Very thick but it's great otherwise as a light indoors sunscreen
I didn't mean to buy two, so definitely gonna return one. Two ounces, but for $12 that's pretty decent! Looks like this is mostly made for just the face and neck, so if you use it for your whole body then yeah, not worth the price. But just for the face? This will last me a long time. Most nice face sunscreens are like $20 for 1.5oz so $12 for 2oz is great. I didn't pay enough attention and saw that it was SPF 30 once it got here. Which has me very confused because there's 24% zinc in it. That's almost the cap. Much higher SPF products have half that amount. It also has other plant extracts which are said to boost spf so I really don't get why this is so low. I'm hoping the ppd at least is high, even though we have no way of really knowing with American sunscreens and even companies who do measure are greedy with that information and refuse to tell. So we are left guessing most of the time. But, SPF is UVB rays. UV-burning. Ppd is UVA. UV-aging. Apparently American sunscreens have terrible UVA protection, or they just don't tell us at all. So the fact a few people in here were saying they were tanning through this sunscreen shows me that perhaps it's not very high, or that this is more of an incidental "I'm not going outside too much" sunscreen. Which, not surprising. SPF 30 lol. Its very thick and moisturizing, so this seems like it would be the perfect winter sunscreen when the UV index is low and the air is dry. Its also difficult to find tinted sunscreens for very fair skin. And on the off chance there is one, it's usually either too dark anyway, or has an orange tint. This one may be a sunscreen not best for darker skin types but man is the tint perfect for the palest of us! It has light coverage too. I mean my flaws aren't blurred or anything but my acne scars are a bit lighter colored. And the great thing about tint, is it gives protection again VL/visible light. Only tinted sunscreens offer that extra bit of protection. I just wish the spf were higher! It also has a very light orangey smell. Also is water proof. So they say. It washed off a bit too easy for me to believe that though. All in all it's a nice sunscreen. But I don't think I will re-purchase this once I run out in the warmer months, though I may consider it again once fall hits.

Clean ingredients, great price, but...
I want to love this product but I personally can't stand the oily texture and the smell. Maybe if you have super dry skin it will feel great on your skin PROS: The ingredients are great! super clean, the percentage of zinc oxide is perfect and almost the highest % recommended by dermatologists, so it protects the skin really well, no white cast because it's slightly tinted (a little cast at the beginning then it fades away) CONS (in my skin): it leaves my face super oily I have to use rice paper after I apply it to absorb the oiliness [sigh], I don't like the smell it bothers me a lot, it smells like old makeup.
