DEMO 1 mint demo Emotiva SA-250 Limited Edition Stereo Power Amplifier with our Signature Edition upgrade & our RFI EMI RIDDANCE Technology installed throughout for amazing performance 

The Emotiva Stealth SA-250 Studio Reference Power Amplifier gives you two channels of superb low noise, low distortion amplification, coupled with an unbeatable selection of pro features, all in a single professional caliber package. The result of this exceptional technical performance, combined with the SA-250’s massive faceted aluminum face plate and over-built chassis, is a truly iconic amplifier. The SA-250 is a unique overachiever, equally at home in a top-notch home audio system or a high-end mastering studio. If you’ve been searching for a truly exceptional two-channel power amplifier, look no further.

Audiophile Sound

First and foremost, the SA-250 is a stellar performer. Of course, the SA-250 has excellent specifications, but by now you know that specs don’t tell the whole story. Perfectly stable; pristinely pure, almost limitless power; stunning dynamics rising from a black background; never the slightest hint of strain or signal compression; absolute composure under even the most stressful operating conditions. Those phrases can only begin to describe the Stealth SA-250. You must experience it for yourself.

Stealth Construction and Styling

The SA-250 sports a heavy-gauge reinforced solid steel chassis with extensive internal bracing. The front panel, machined from a solid slab of aluminum and finished in jet-black, looks like it was pulled from a military aircraft – or maybe some futuristic weapon. The power button is also black, to reduce visible distractions, and even the channel status LEDs can be switched off for silent running.

Professional Features

We’ve included a full complement of professional features in the SA-250. Balanced inputs are combination XLR and ¼” jacks; unbalanced inputs are solid machined gold-plated RCA panel jacks; and speakers connect via heavy-duty gold plated audiophile grade binding posts. Each channel has its own fully independent input selector, ground lift switch, and gain control switch. For convenience and practicality, the SA-250 runs on either 120 VAC or 230 VAC, uses a standard IEC power cord, and can control, or be controlled by, other standard trigger-enabled equipment.

Under the Hood

Inside, a super heavy duty power supply, featuring a 1200 VA toroidal power transformer with dual secondary windings, rectifiers, and 40,000 uF of independent, low ESR energy storage for each channel, providing high inter-channel isolation and ensuring that the SA-250 never runs out of power. Our fully discrete, highly optimized dual differential, high current, short signal path Class A/B amplifiers modules deliver massive power with vanishingly low distortion and noise; premium components throughout promise you years of quality service; and, on the off chance that something does go wrong, our unprecedented five year transferrable warranty has you covered.
