FIIO K17

De Nieuwe Generatie Desktop DAC & Hoofdtelefoonversterker

De FIIO K17 is meer dan alleen de opvolger van de K9 Pro—het is een gedurfde stap voorwaarts in desktop-audio. Met een mix van retro-elegantie en geavanceerde technologie biedt de K17 een krachtig en verfijnd ontwerp boordevol functies. Het zet een nieuwe standaard voor hoogwaardige DAC- en hoofdtelefoonversterkers.

Hoogwaardige DSP & Geavanceerde Kloktechnologie

Centraal in de K17 staat de M21586Q DSP-chip, die 64-bit floating-point bewerkingen met dubbele precisie uitvoert op een indrukwekkende kloksnelheid van 360 MHz. Deze wordt aangevuld door de krachtige ES9821Q ADC en een op maat gemaakte femtoseconde kristaloscillator met ultralage faseruis. Samen zorgen ze voor ondersteuning van een 31-bands verliesvrije PEQ in alle modi—zonder verlies van signaalintegriteit.

Vlaggenschip DAC-architectuur

De K17 is uitgerust met AKM’s topklasse DAC-configuratie: de AK4191 in combinatie met twee AK4499EX-chips—één per kanaal. Dankzij het 8-naar-4-kanaals LPF-ontwerp wordt gemeenschappelijke modus-interferentie geminimaliseerd, wat leidt tot betere kanaalscheiding en dynamiek. De volledig gescheiden digitale en analoge secties, samen met AKM’s nieuwste “DWA ROUTING”-technologie, zorgen voor een stillere achtergrond en hogere resolutie.

Volledig Aanpasbare PEQ

Met de geavanceerde PEQ kunnen gebruikers het geluid tot in detail afstemmen. Ondersteuning voor PCM-signalen van 44,1kHz tot 96kHz, een instelbaar versterkingsbereik van +12dB tot -24dB en Q-waarden van 0.4 tot 128 bieden uitgebreide controle. Instellingen kunnen eenvoudig opgeslagen, gedeeld, geïmporteerd en geëxporteerd worden—ideaal voor het simuleren of corrigeren van frequentieresponsen van verschillende hoofdtelefoons.

Nieuwe Discrete Versterkerarchitectuur

Voor het eerst gebruikt FIIO in een desktopmodel een discrete versterkercircuit met een OP + transistor-stroomversterkingsontwerp. Met ON Semiconductor MJE243/253-transistors levert deze versterker een hoge stroom met lage uitgangsimpedantie, goed voor een vermogen tot 4000mW + 4000mW in gebalanceerde modus—bijna het dubbele van de K9 Pro ESS. Het resultaat: moeiteloze aansturing van allerlei hoofdtelefoons en IEM’s, met een natuurlijk, soepel en rijk gedetailleerd geluid.

Adds comfort and support
Color: Green, Size: Twin
I’ve been using this bamboo mattress topper for a couple of weeks now, and it completely changed the feel of my bed. My mattress was starting to feel too firm and uncomfortable, especially on my lower back and shoulders, but this topper added the perfect amount of cushioning without making the bed feel overly soft or saggy. The cooling effect was one of the biggest surprises. I tend to sleep hot and usually wake up sweating during the night, but the bamboo-derived fabric feels breathable and much cooler than regular mattress pads I’ve owned before. It stays comfortable throughout the night and doesn’t trap heat like memory foam toppers sometimes do. I also really appreciate the waterproof protection. It gives peace of mind without feeling stiff or making that annoying crinkling noise some waterproof covers have. The surface still feels soft, plush, and smooth. It honestly feels more like a hotel-style pillow top than a basic mattress pad. The thickness is just right for pressure relief. It helped reduce the soreness I usually wake up with in my back, and I’ve been sleeping much more comfortably overall. The deep pockets also held securely on my twin mattress and didn’t slide around, even after moving a lot during sleep. Another thing I liked was how fluffy and well-made it looked right out of the package. After letting it expand for a bit, it became nicely plush and evenly padded. The stitching seems durable, and it still looks great after washing. If you’re looking for a softer, cooler sleeping surface with added waterproof protection and better support for aches and pains, this mattress topper is definitely worth it. It made my bed feel newer and far more comfortable without needing to buy a whole new mattress.

BDEUS Twin Mattress Topper, So Soft
Color: Green, Size: Twin, Color: Green, Size: Twin
Having purchased BDEUS products in the past, I was very looking forward to ordering the mattress topper made of viscose (a material derived from bamboo) just to see (and feel) the benefits of the material. My concern about the material, viscose derived from bamboo, is that the process to manufacture the material can be chemically intensive leading to harsh smells. I can say the topper has no off-putting smells. The quality of the manufacturing is present as there are no loose threads/seams, the material has no defects, and the print is uniform. The use of the material also leads to increased durability while enhancing the topper’s breathability and cooling properties. The topper is fitted meaning the topper will not come off the mattress very easily (even though you may need sheet straps if you are a wild sleeper). But the softness is wild, I mean this has to be one of the softest materials I have felt, and it feels very luxurious. Waterproofing and moisture-wicking is also a benefit as small spills are not absorbed into the fabric. The topper is also very thick and plush, and while the product listing touts “Back Pain Relief” it may be too soft depending on how firm, or soft, you prefer your mattress. I have to say this is definitely a five-star offering from BDEUS. This topper is for my daughter but I’m going to order a queen-sized topper for my bed as the price is just right.

This topper has definitely provided me with better, more comfortable sleep.
Color: Green, Size: Twin
I recently tried a twin mattress topper made from bamboo-derived viscose, and I'm quite impressed. The topper is thick, waterproof, and offers excellent comfort, especially for those who struggle with back pain or sleep hot. The bamboo and polyester blend gives it a soft, cooling surface that's perfect for a restful night's sleep without the sweaty feeling often associated with memory foam. What I really appreciate is its dual function. It's breathable, allowing for good air flow, and fully waterproof, which helps keep the mattress underneath safe from spills. This is especially useful if you have kids or pets. The topper's thickness is just right—it provides great support without feeling too soft or too firm. It cradles pressure points well, offering relief to my hips, back, and shoulders. The fluffy filling holds up well over time, maintaining its softness and support. It fits securely on mattresses, thanks to a deep pocket skirt that prevents any sliding or bunching. This topper has definitely provided me with better, more comfortable sleep.

Soft and comfy
Color: Green, Size: Twin, Color: Green, Size: Twin
This mattress pad is much thicker and fluffier than the one I had before. With I took it out of the package, it was vacuum sealed with a note saying to leave it out in the sun for 48-72 hours or fluff it up with a hair dryer. I put it in the dryer on medium heat, which worked nicely. The pockets are really deep on this mattress pad and it fits snug. You don’t really see the shape with a sheet on top. It feels comfortable laying on top of it. It doesn’t flatten much when I’m laying down, but I imagine over time it will lose fluffiness. Overall it’s comfortable and breathable.
