The CA1 Control Amplifier is a next-generation complete amplifier system using our newly developed Advanced Nested Architecture (ANA). You only need to add a turntable, DAC, or similar source and a set of loudspeakers (or headphones) to create a fully functional music system.

The CA1 Control Amplifier oozes with the transparency, dynamic range, linearity, and pure music for which Audio by Van Alstine is known. Listen to all of your recordings again and you will hear acoustic space and musical nuance in a much more real and involving way. The cost is lower and the performance much higher than you have any right to expect.

Features

The CA1 control amplifier is one of the first products to use our ANA technology,  delivering stunning linearity and sound quality previously unimaginable at its price. It generates up to 55 watts per channel into 8Ω and is suitable for nominal 4Ω loads and up.

A high-performance moving magnet phono preamplifier is standard, as is an equally high-performance headphone amplifier with a 1/4" headphone output. It has four gold-plated RCA inputs, one of which for phono use. The speaker outputs are heavy-duty 5-way binding posts.

Remote control is provided for power, volume, and muting. A 12V trigger output is also provided for those wanting to use the amplifier in highly integrated system setups.

Amplifier Circuits

Our Advanced Nested Architecture (ANA) technology is a major advancement in audio power amplifiers that brings you ever closer to the original source. Unlike more conventional class AB amplifiers, ANA employs two independent control mechanisms to manage circuit nonlinearities. The first mechanism provides the kind of correction found in typical class AB audio amplifiers. To this, ANA adds a second global correction circuit that reduces nonlinearities to the vanishing point. We are confident that you will find the results exhilarating.

Power Supply Circuits

To fully support the incredible dynamic range, bass extension, and transient detail the CA1 Control Amplifier's audio circuits are capable of, the amplifier uses a linear power supply based around a high-capacity toroidal power transformer. All of the power supply parts are selected for long life and reliability and operate well within their technical specification ratings.

Additional Information

The CA1 Control Amplifier operates with standard 120V AC power. It has an IEC power socket, and we include a 120V IEC power cord.

Heavy linen character, but a beautifully tailored suit!
Color: Beige, Size: 4, Color: Beige, Size: 4
This is a really nice linen suit! The jacket is beautifully made and well-tailored, with a fun speckled texture that has lots of pretty color variation (we ordered the beige). When I placed it side by side with a similar linen suit from another brand, the difference in the linen texture was really noticeable — this had a much stronger linen character that stands out! It has three useful pockets on the outside of the jacket, which is great for little hands. The only downside is that one of the inside pockets is just for show (faux), which was a bit surprising and somewhat disappointing for my little guy. The pants have pockets too, but they aren’t very deep — perfect for small treasures, but not much more. The pants are made from a lighter, thinner single-layer linen compared to the fully lined, double-layer jacket, which makes sense for comfort and easy movement. The pants didn’t come with a front crease ironed in, so you’ll want to press one yourself. The linen did pick up some creases from being folded in the package, but it doesn’t seem quite as wrinkly as some other linen fabrics I’ve tried. Still, like most linen clothes, especially for boys, the pants will need occasional ironing to keep them looking neat and crisp, especially after a day of play and general wear. The structured, lined jacket stays looking smoother and more put-together with less effort. It also came with a bow tie, a neck tie, and a tuxedo-style white shirt as extras. The ties aren’t great quality — they’d work fine for quick photos but probably won’t hold up to much actual wear. The formal white shirt feels a bit funny paired with the casual linen suit, but I don’t mind at all. We already have white shirts that we prefer, so we’ll use those instead. For us, the extras are really just bonus items we won’t plan on using. Overall, it’s a handsome little suit that’s perfect for special occasions like weddings, family photos, or holiday events. My kid looked adorable in it! The stronger linen texture on the jacket gives it a premium feel that I really like. Just be ready for a bit of extra care with the pants to keep everything sharp.

Great suit set
Color: Light Grey, Size: 4
It is incredibly attractive and includes everything a young child needs for a special occasion. The material is a 75% polyester and 25% linen blend, and the outer fabric feels remarkably smooth. Its unstructured design allows for an attractive, natural drape, and the blend conveniently allows for machine washing at home. As is typical with linen-based materials, the fabric can be naturally stiff and prone to wrinkling, so I recommend ironing or steaming it before use. The lightweight feel makes it an excellent choice for the spring, summer, and fall months. Overall, this suit offers exceptional value for the price.

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.
