SA-250 Limited Edition Power Amplifier
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.
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.
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.
