Ypsilon AELIUS II

Mono Block Hybrid Power Amplifier

Aelius II is a push-pull hybrid mono block power amplifier (pair) using only two gain stages with no overall feedback. It has been designed to provide power to drive real world speakers with unmatched transparency and musical involvement.

The first gain stage is implemented with a valve, operated in single-ended class A and transformer coupled to the output stage. The use of a transformer negates the need for an additional gain stage, so the transparency and purity of the signal is preserved. For this purpose, a wide bandwidth (10-75 KHz) transformer was developed using extensive listening tests and measurements. The bandwidth of the transformer also defines that of the amplifier.

The Aelius II also features a recently developed special input transformer which extends the purity of the signal path even further. It also gives the opportunity of a balanced input in the amplifier, thus giving the user the versatility of using longer interconnect cables if required.

The output stage uses components of the same polarity (N-channel), working in the same topology. The output of the amplifier is symmetrical so both output connectors (+, -), carry the signal in the opposite phase. Great attention was also paid to the design of the power supply, which uses high current inductors for smooth and quiet filtering.

The Aelius II is most certainly a revolutionary product having a unique set of features, refinement and transparency with real-world power and control over the speaker.

Reviews

The Audio Beat, Marc Mickelson, 2012

The Ypsilon Aeliuses… are certainly “truly great amps.” With them, it is the sum total of everything they do — all to a very high level — that’s distinguishing, and that so much of what they achieve is rare among amplifiers no matter the price. I’ve heard amps that track the signal with as much speed as the Aeliuses and amps that are as quiet as the Aeliuses, but not amps that possess these qualities along with the same midrange dimension and the same bass power — the same level of overall realism — as the Aeliuses, all in one package.

The Aelius is yet another spectacular sonic and technological achievement from Ypsilon Electronics. I remain impressed by everything they do.

Must-Have for Active Dogs!
Style: Sport, Size: Large
The Chuckit Sport 26L Dog Ball Launcher has been a game-changer for my large dog! My 80-pound Labrador loves to play fetch, and this launcher makes it so much easier and more enjoyable for both of us. The 26” length gives me the leverage to throw the ball much farther than I could by hand, which really helps burn off my dog’s energy. The included large ball (3”) is the perfect size for big dogs, and I appreciate that it’s made from durable rubber, so it withstands a lot of chewing and rough play. What I really love is that the launcher is so lightweight and easy to use. I can play fetch with my dog for extended periods without my arm getting tired. The ergonomic handle also provides a comfortable grip, which is a nice touch. If you have a large, active dog, the Chuckit Sport 26L is a must-have. It’s well-made, durable, and makes fetch more fun for both you and your dog. Highly recommend!

ChuckIt is AMAZING!
Style: Sport, Size: Large
I can't throw a ball to save my soul. Just got this today and lobbed a ball to the far end of my 1- acre yard. The dog loves it, and I love it!

I recommend using the KONG Extreme Dog Toy
Style: Sport, Size: Large
Helpful for throwing as much as my dog wants to fetch. I actually had to get a cortisone injection in my shoulder a few months after getting my dog - never had a dog with this much energy before! The Chuckit really helps. Downside: The ball that comes with it is larger than a tennis ball, so may be too much for smaller doge. I can't imagine my sister-in-law's french bulldog carrying it! Also, in our house it gets destroyed within minutes, as my dog is a strong chewer. For this situation, I recommend using the KONG Extreme Dog Toy, Black, size Large. This is shaped sort of like a snowman, which means it bounces unpredictably at times. My dog eventually chews the "head" off of this toy, but the remaining 2/3 still fits in the Chuckit (and is actually easier to throw with the "head" missing!). One caveat: the KONG is significantly heavier than the ball included with the Chuckit, so be aware of that... Also, we ordered our first Chickit in October 2015, then needed to replace it in May of 2017, as it broke. I think the plastic became brittle over that time, as we left it out in the sun & rain in Florida. Since it is cheap to replace, that's not a big deal. (We ordered three Kong toys over that same period of time!) To summarize, it's a very helpful tool to get the ball further, faster, with less strain, than without it. Knowing there are alternatives to the included ball for heavy chewers makes it worthwhile.

Great Ball Launcher!
Style: Sport, Size: Large
Our dogs love this ball launcher! I can throw the ball long distances without any arm strain. The balls wear out, and as described by others, tennis balls don’t fit. Buy extra balls if this is of concern. We bought a few of the “Chuck It” rubber 3” balls and they have worked well for our dogs. It’s a great value and fun for the dogs.

Chuckit!! Just Chuck it!!
Style: Sport, Size: Large
Chuck it further than your skinny little arms can chuck it. Doggo loved this, I loved this and when we were done Doggo promptly hid it under the porch so I couldn’t take it from him. It’s not a squeaky toy, it’s for fetch. You wing it out toward the yard and it flies, bounces if it’s lucky then is attacked in an adoring manner. We like it!!
