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.

ATI Amplifier Technologies - AT 1800 Series - Multi-Channel Stereo Amplifier
Available in six configurations, the AT1800 series shares many attributes with is larger siblings: AT2000 and AT3000 series'. Because of the large heat sinks that cool the amplifier, there are no cooling fans which allows for perfect listening without any fan noise. In the case of an overload situation an optically-couples protection circuit automatically shuts down the amplifier. The conditions are checked every ten seconds once a protection circuit is engaged and output is automatically restored once the overload situation has been remedied. There is no direct electrical connection because the protection circuit is optically coupled to the audio circuit. This allows for protection without compromising the sound quality.
The need for cumbersome fuses is eliminated with a provided magnetic circuit breaker with also provides further protection. The AT1800-series amps use the same transformer construction as the top-of-the-line AT3000 and AT2000 series amps: MOH cores with bifilar windings, built in our own factory. Powder-coated chassis and double-sided glass epoxy circuit boards are used in all ATI products. Most high power amplifiers draw a tremendous inrush of electrical current when turned on. The AT1800-series amplifiers do not due its Ultra Soft Turn-On Circuit. The circuit power the amplifier on gradually to ease the load of household circuits. The amplifier is turned on and off via included trigger input.
