Product Details

Topping TP23 T-Amp USB Class T Amplifier 25WPC

We don't make the pronouncement lightly, but the Topping TP23 may possibly be the perfect desktop amplifier!

It is a dedicated computer amp, having only a single USB input. Plug the TP23 into a Windows, Mac, or Linux computer with the attached USB cable and it should be instantly recognized as an external sound card. The TP23 will turn on or off depending on the presence of the USB signal from the computer – the only control on the amp is a big, friendly volume knob, front and center.

Speakers wires are attached using the mini binding posts on the back of the TP23. At the heart of the amplifier, there's a Tripath TP2021B IC providing 25 watts x 2 of Class T power, enough for all but the very most demanding nearfield applications.

Operation couldn't be simpler, performance is top-tier, and the construction is every bit as good as you've come to expect from Topping. The TP23 includes a rugged chassis with thick, brushed aluminum faceplate. Inside the amp, you'll see lots of high-quality, name-brand components from TOKO, ALPS, KOA, Nichicon, and EPCOS.

Specifications: • Output power: 25W x 2 (4 ohms, THD 10%), 14W x 2 (8 ohms, THD 10%), 13W x 2 (4 ohm, THD 0.05%) • Size: 4.06" W x 1.46" H x 6.54" D  • Power requirement: 14 VDC, 4A (supply included) • Weight: Main unit only 0.91 lbs.; Package (including power supply): 1.55 lbs.

Topping TP23 T-Amp USB Class T Amplifier 25WPC
Topping TP23 T-Amp USB Class T Amplifier 25WPC is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Great Computer AudioI've been using this with a Win 8.1 desktop and old school AR-4x speakers for several years. Sounds just great! Turns on and off with the computer and has a nice big volume knob if my software won't compensate. Plenty of power, plenty of sound. Well built, quality piece. Highly recommended.

Rated 5 out of 5 by from Topping TP23 - Why I Love It!I was looking for an amp for my new Audioengine P4 speakers (awesome speakers). Audioengine does make there own amp for $200 but I thought I would take a chance and buy the Topping TP23 (almost half the price) because parts-express said it was one of the best amps (in this price range) that they had ever heard. I agree! The amp is quite small and well built, very stylish on my desktop, works as advertised, and most importantly makes the speakers sound great. Love this amp and love buying from parts-express.

Will the USB input work from a portable device like an iPod or iPhone?

Wondering if this device is only compatible with laptop or desktop USB outputs
