Product Details

Topping TP32 Class T Amp with USB and Remote 15WPC

The Topping TP32 fully digital amplifier places older linear amplifiers on notice. Not only is the TP32 a fraction of the size that you would expect with high quality linear amplifiers, it replaces the most troublesome analog part—the volume control—with a Cirrus Logic CS3310 low distortion digital volume control system. This also enables complete control with the included IR remote.

The microprocessor controlled volume control system also syncs to your PC, when connected via USB (USB A-Male to USB B-Male cable sold separately). When you turn your PC on, the Topping TP32 automatically turns on. Turn your PC off, and the TP32 shuts down. This is of course bypassed when using the stereo RCA audio input and can be disabled.

A Burr-Brown PCM2704 DAC with an on-chip direct USB interface is used to maintain absolute fidelity with an almost immeasurable total harmonic distortion plus noise measurement of 0.008%! This DAC supports 32, 44.1, and 48 kHz sample rates at 16-bit resolution. An amplified gold-plated 1/4" stereo headphone out makes the TP32 a perfect all-in-one solution for high resolution monitoring—perfect for audio engineers!

Only the absolute best components are selected in the design of this amplifier: KOA resistors, ERO, Nichicon, and Siemens capacitors, TOKO inductors, Omron switches, and a Fujitsu relay. The critically-acclaimed Tripath TA2024B is used for amplification and delivers up to 15 watts per channel into 4 ohm loads. Last but not least, everything is housed in an extruded aluminum chassis that features CNC-cut front and backplate. World-compatible 12 VDC, 3A power supply included.

Topping TP32 Class T Amp with USB and Remote 15WPC
Topping TP32 Class T Digital Amp with USB and Remote 15WPC is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Wonderful performance for a computer-linked office sound systemWith the generic sound card on my office computer, it is a real plus that the TP32 has a USB input and an inboard DAC.Sound quality is first rate, although at 10W/channel @ 8ohms, it cannot drive my Dayton B652 bookshelf speakers to more than a moderate volume level. This does not pose a problem for an office sound system.Between internet streaming audio and a ripped CD collection, my desktop computer provides a great music source.

Rated 5 out of 5 by from This amp is a gem!I originally bought this amp for my transportable demo set up. I was stunned when I plugged this in. Expecting harshness, I was shocked to find sweetness. This thing is detailed, dynamic & very tube like. It projects a wide & focused much so I have not turned my regular system on for weeks!Now...I let you into a little secret. The headphone output can be selected to be active at the same time as the speaker outputs. This means it acts as a separate pre-out to drive your subwoofer amp. What other amp can do that? Brilliant!There is no resistive volume control to deteriorate the sound, all done digitally by chip.Extra bonus....remote contolled!Average on features because it only has one analogue input, but I got round that by making my own switch box.Built in DAC only average too, but I am comparing it to a state-of-the-art product. Snap this up before everyone else finds out about it!

Topping TP32 Class T Amp with USB and Remote 15WPC

Can the remote be purchased separately (to replace one that the kids damaged)?

Asked by: DaveJS
Unfortunately we do not offer the remotes separately for these amplifiers.

Future model question?

Anyone know if they are planning to offer a model that has the remote like this AND toslink spdif input? That would truly be perfect for upgrading the sound from my flat panel TV that only has toslink output.
Asked by: Honest Rob
I have not heard of any plans for what they have coming in the future, but I will pass the suggestion along to them .

Will the USB input read WAV or FLAC or any other formats other than MP3's?

Asked by: Dingman
The USB input will support any audio that you play on your PC. Essentially when you connect to your PC it will see it as a plug&play audio device. If you choose it as the default output device on your system then all audio (whatever you play) will be feed into the amp.

Can audio be transferred via USB or just the RCA analog input?

Does the USB input accept an iPhone and allow digital audio transfer? In short, I don't want to rely on an analog input.Also, when connected to a computer (specifically a Mac) via USB, does it somehow allow audio transfer via USB?
Asked by: Lukasz
These are good questions. These USB amps only READ flash drives. There are no "smart chips" or microprocessors inside to read/xfer dig-aud from iPods or other computers. If they did they would cost $400.
