D-MAX Technology
Ashly's all-new proprietary D-MAX technology brings together smart and cutting-edge amplifier design, a brand-new ultrafast switching power supply with silicon carbide semiconductors and diodes, and intelligent power management to deliver ultimate efficiency.
- When current and voltage are exactly in phase, current demand is reduced and efficiency increased. Dynamic Power Factor Correction tracks current continuously to maintain accurate monitoring and control.
- Silicon carbide semiconductors boost both speed and efficiency and are significantly faster than the old-school pure silicon of the past.
- Traditional silicon semiconductors don’t shut off instantly. They have a lag time called Switching Loss, leading to a residual tail current. From an audio-quality standpoint, this makes for a sloppier, less precise sound; from an efficiency standpoint it sucks up unnecessary power.
- Instead, Ashly is pioneering the use of silicon carbide semiconductors. They have unique electrical characteristics that render them able to switch on and off far faster than conventional silicon. The result is an amplifier design that’s faster (has better audio fidelity) and is more efficient.
SailFlow Cooling Architecture
- Power amplifiers need cooling. In most amps, heat-reducing airflow takes a convoluted path in and around internal components. Front-to-back, back-to-front, or side-to-side, those nice perforated grilles look simple until you look inside the amp and see the helter-skelter airflow.
- Ashly didn’t want cooling air to just wander around inside the EcoTour chassis, so it came up with its unique SailFlow architecture, which directs internal airflow strictly over the areas that generate the most heat, rather than arbitrarily over the whole amp. This keeps the already highly efficient EcoTour Series even cooler and assures reliable, stable operation, even under heavy loads.

Dog approved.
Size: X-Large, Color: Cheese
I’m a 70 lbs Goldendoodle (supposed to be 65, don’t ask) and I love cheese. Real cheese. Sharp cheddar with sourdough bread is my dream, but apparently I’m “on a health journey,” so my people bought me this instead.
Does this bone actually taste like cheese? No. I am not fooled.
Do I still enjoy chewing it loudly while my humans are trying to watch TV? Absolutely yes.
This bone satisfies my need to chew and my emotional desire for cheese-adjacent activities. It keeps me busy, saves the furniture, and lets me crunch dramatically during important dialogue scenes. The yellow color is nice — very cheese-coded — although some cheeses are white, so just something to consider for future versions.
Also, good news: it doesn’t smell like cheese at all, which my humans seem very grateful for. Apparently they don’t want the carpet to smell like a deli. Weird.
Final verdict:
Not cheese.
Still enjoyable.
Would chew again.

A Humorous Twist on Tough Dog Toys!
Size: Large, Color: Lobster 3 Pack
I recently purchased the Nylabone Power Chew Dog Toy Pack for Aggressive Chewers from Amazon, and I must say, these toys have been a hilarious hit with my furry friend. As a dog parent of a strong and determined chewer, finding toys that can withstand their chewing prowess is a top priority, and these toys deliver both durability and a touch of humor.
The pack consists of three large/giant-sized toys in the shape of a lobster, cheese, and broccoli. The unique and amusing design puts a smile on my face every time I see my dog interacting with them. The unexpected twist brings a playful element to our daily playtime sessions, making it a fun and engaging experience for both of us.
When it comes to durability, these toys excel. My dog can be quite aggressive with their chewing, and I've struggled to find toys that can withstand their powerful jaws. However, the Nylabone Power Chew toys have proven to be impressively tough and durable. Despite rigorous chew sessions, these toys have remained intact, with no signs of wear or damage. They provide a reliable outlet for my dog's chewing instincts without the risk of shredding or ingesting any harmful materials.
The textured surfaces of these toys add an extra layer of interest for my dog. The ridges and raised bumps provide sensory stimulation, promoting healthy oral hygiene and helping to clean teeth and gums as they chew. I appreciate the added dental benefits these toys offer, as it helps maintain my dog's dental health while they engage in play.
I also appreciate the size options available in this pack. Large and giant-sized dogs often require bigger toys to accommodate their larger mouths and chewing strength. The included toys are appropriately sized for larger breeds, ensuring a comfortable grip and maximum enjoyment during play sessions.
As a bonus, these toys are made from high-quality, non-toxic materials, so I have peace of mind knowing that my dog can safely interact with them. Safety is a top priority for me, and Nylabone consistently delivers in that regard.
In conclusion, if you have an aggressive chewer and are in search of durable, funny, and engaging dog toys, the Nylabone Power Chew Dog Toy Pack is a fantastic choice. These toys provide hours of entertaining play, withstand even the most determined chewers, and offer dental benefits. Embrace the humorous twist and enjoy watching your furry friend engage in safe and engaging play with these fantastic toys.
Invest in the Nylabone Power Chew Dog Toy Pack today and let the lobsters, cheese, and broccoli bring laughter and durability to your dog's playtime!

Shark dog approved
Size: Large, Color: Broccoli, Size: Large, Color: Broccoli
My new baby shark.... I mean puppy really enjoys chewing. I can't just give her a ton of pig ears or bully sticks all day, which she would definitely love, so I'm constantly looking for well made chew toys. I'd put this right up with Kong. Very durable and nice. I also love the different textures, she seems to also love it. She can gnaw at the top and chew on the stem. She wanted it as soon as I opened it - it does smell like bacon but I haven't taken a chomp at it to be able to write a complete review!
My dog is about 23 lbs but I can see a 80 lb dog chew this, it's not small.

So cute
Size: Large, Color: Pumpkin
My French Bulldogs have really strong jaws and are aggressive chewers. These really are sturdy and last a good amount of time. They are a bit heavy and awkward for my dogs to hold onto but they do like them.
