The Purifi 1ET6525SA is the successor to the highly acclaimed 1ET400A. Incorporating 2nd Generation EIGENTAKT advancements from its bigger brother (the 1ET9040BA), the new 1ET6525SA has lower output noise, higher SNR, lower distortion, and more power output (up to 510w per channel) compared to the original 1ET400A. All of the ultra-low distortion and high-power output of the original 1ET400A is now improved even further and lives on as the new 1ET6525SA.

With its completely flat frequency response and high power output, our 2ch Purifi 1ET6525SA is a top tier choice for those with critical 2ch listening setups, allowing for users to hear the source material as it should be without any added distortion or "coloring" of the sound.

Gain Settings

• 4 ohm - 25dB/2.2Vrms (High), 20dB/3.9Vrms (Medium), 15dB/6.9Vrms (Low)
• 8 ohm - 25dB/2.3Vrms (High), 20dB/4.0Vrms (Medium), 15dB/7.1Vrms (Low)

High input gain setting matches up with the input gain of the Hypex amplifiers, perfect for those wanting to mix Purifi amplifiers with Hypex amplifiers (such as for a home theater setup).

RCA vs. XLR
While our amplifiers use XLR inputs, it is perfectly fine (and fully supported by Purifi) for customers to use RCA to XLR cables to connect the amplifier to a source that only has RCA outputs.

Our cases may not be much to look at, but unlike our competitors who use overseas manufacturing, we have all of our cases manufactured in Nova Scotia, Canada (Protocase, Inc). This is part of our commitment to keep as much of our amplifiers as "home grown" as possible. It also ensures the highest possible quality aluminum and extremely precise CNC manufacturing.
