Do you really price match?
We will match any e-Commerce (Online store) Authorized USA Dealer's advertised price. Please call us toll free (877) 370-1972 and alert us to where you found the product cheaper. We will verify, and if the site is an Authorized US Dealer- we will match their price. However, if the price is below the manufacturer Minimum Advertised Price (MAP)- we will have to get authorization to match the price. We will not violate our signed agreements that we have with our vendors.
What about price matching from an auction site?
We do not price match any auction or "grey market" site.
Be advised, any purchases from an auction or unauthorized (grey market) websites can lead to future issues in regards to warranty or support. Most manufacturers will not honor any claims or warranty from these type of sales. Spend your money wisely by purchasing from an Authorized Dealer. In a lot of cases, saving a little bit of money can cost you more after the sale is completed.
We offer a 30 Day Return Policy should you choose to return a product for any reason.
Since 1972 Sound Approach has backed all items that we sell. If the product you have purchased is not right for you, let us know. We strive to find the right product for your unique situation. We will work with you to find a sound solution and recommend what product will resolve your issue. That being said, we will credit, refund, or exchange any product you purchase within 30 days of your purchase.
Certain products, may be returned, but are subject to a restocking fee of 20%. Please contact us to determine, before ordering, if the item will fall into this category. Usually it is for the high-end electronics & audiophile-grade speakers. We want to make sure that we match you with the correct product, so please call and speak to any of our technical experts prior to ordering.
Four Important Conditions:
1. We need to get the original box, manuals, and any materials that came with the product for you to receive a full refund- with no re-stocking charges. The item/product must still be in like-new condition.
2. If the item had Free Shipping and you are returning a non-defective product, the original shipping cost will be deducted from the total that will be refunded back.
3. Special Ordered items are not returnable (see below).
4. Once an RMA is issued- it is valid for 10 business days. After 10 days, the RMA is canceled and returns will not be accepted.
Shipping and handling charges cannot be reimbursed unless it is our mistake. Yes, we can make mistakes – not often, but it can happen.
ATC - SIA2-150 - 150w x 2ch Integrated Amplifier
Welcome. In selecting ATC you have chosen an example of the finest audio engineering available. ATC was founded on a principle of engineering excellence, and that principle still defines our products today. Given the right opportunities, ATC products will deliver exceptional audio performance, but the opportunities will only arise from careful and thoughtful installation and use. Please read the included manual fully. It will help you understand the product and to realize its full potential.
ATC was founded in London in 1974 by Australian émigré Bill Woodman, who still heads the company today. An enthusiastic pianist and engineer he was naturally drawn to loudspeaker design and, after a period working at Goodmans (where many of the names that went on to found British loudspeaker companies began their careers), he struck out on his own. The premise on which ATC began is a simple one – and one that, in many respects, is still true today: hi-fi loudspeakers tend to be detailed and accurate, but of limited dynamic range, while professional monitor speakers tend to express the opposite character. ATC products were designed from the outset to offer the best of both. It’s an easy concept to describe, but surprisingly difficult to engineer.
The difficulty inherent in designing such loudspeakers is one of scale. Hi-fi levels of accuracy and detail call for lightweight moving parts and delicate engineering. Professional monitor levels of performance, however, demand far more robust components engineered to survive the rigors of high-level use for extended periods. The only way to combine the two is through precision engineering of a class and scale more often associated with aerospace or motorsport. But the results are worth the effort and the cost. ATC loudspeakers, with their unique in-house designed drivers, combine the best of hi-fi and professional to devastating effect.
ATC has become synonymous with active systems. Choosing to offer active loudspeakers (where the passive systems still have their place, and ATC engineering skills can still bring remarkable results from them) is a fundamentally better solution to the problems posed by accurate, high-level music reproduction. The ATC instinct is always for a better solution. Not cheaper, not quicker, but better. It was the development of active loudspeakers that first brought ATC into electronics design and engineering. Active speakers demand multiple power amplifiers, so ATC from the mid- 1980s became not just a loudspeaker manufacturing company but an electronics manufacturer, too. The further step from electronics for active speakers to a range of stand-alone amplifier products was natural and now means that ATC engineering is available from the recording desk or CD player output to the ears.
From modest beginnings, ATC has grown to become one of the very few manufacturers successful across both domestic and professional audio. By selecting ATC you join a group of music lovers, professional audio engineers, studios and musicians across the world that understand and value the engineering that goes into an ATC product.
