Overview

30400 Specs

The Silverback Class-T Amplifier packs all of the audiophile sound quality you expect from Silverback products into a compact design. The Silverback amp uses a high-performance chipset that delivers 50 watts of continuous power per channel into an 8 ohm load for a 100 watt total. Because it uses Class-T amplifier circuitry, the Silverback amp offers all of the audio fidelity of a Class-AB amplifier while providing the power efficiency of the Class-D amplifier design.

With RCA and 3.5mm connections, the Silverback amp can be used with a variety of different audio sources from stereos, to computers, to tablets and smartphones.

Speaker output connections are high-quality banana plug receptacles. Banana plugs ensure a solid connection, which gives you great sound and a cleaner look. The Silverback amp includes gold plated banana plugs, so you don’t have to worry about buying additional products to set up your amplifier.

In addition to the banana plug connections, the amp also features a 1/4" stereo jack for larger home and studio style headphones. It has a 3.5mm adapter so you can also use smaller headphones. The Silverback amp can function as a high fidelity headphone amplifier. It delivers a colossal soundstage from 20 – 20,000 Hz with a signal-to-noise ratio of 103 dB.

Pros: Using to power a set of Pioneer BS21 speakers. I don't have a lot to compare it to, but this amp sounds quite clean even when turned way up, and is more than loud enough for my apartment needs. The second input and headphone jack are much appreciated.

Cons: No input selection switch or balance control

Pros: Wonderful sound for such a small footprint. The quality control appears to be outstanding. The aluminum faceplate looks very "clean" with it's darker grey color & large black volume knob. Wattage/Price ratio is great. No obnoxious bright blue power light. Runs very cool even at higher volume levels. Front headphone & 3.5mm jack-in. Gives every accessory for set-up. A real 1-year warranty.

Cons: Wish there was a subwoofer out, but you can still work around that.

Other: I have the Sewell amp hooked-up to a pair of PSB B4 & it's a wonderful combo. I bought a pair of Silverback 6" terminated speaker cables (part # SW-30012-6)It's worth the extra money for a clean install. Bought another just for back-up. Also, Sewell is a great company. Shipping was pretty fast from Utah to Massachusetts.
