The Topping T41 audio amplifier is based on a Tripath TA2021 circuit giving it the same performance of D class amplifiers. The T41 can be used to drive even the most demanding speakers to even your headphones via the headphone out built into the front of the amplifer. The sound quality produced retains sound clarity with a powerful bass. The T41 can be used with your speakers for your PC, CD, DVD or just with your headphones.

Features:

  • High power (25Wx2).
  • Dual input
  • Very high efficency (88%).
  • "Audiophile" quality sound.
  • Speaker protection circuitry.
  • Headphone amplifier built in.

Specifications:

  • T-Amp IC Tripath TA2021
  • Output Power 2 x 25W
  • Signal-to-Noise Ratio (SNR) 98dB
  • Dynamic Range 98dB
  • IHF-IM Distortion 0.1% @ 1W, 4ohm
  • THD Distortion
  • 0.05% @ 13W, 4ohm
  • Power Efficiency 81% @ 25W, 4ohm, 88% @ 13.5W, 8ohm
  • Input Sensitivity 200mV
  • Dual RCA audio input jacks
  • Speaker out ( L & R)
  • Headphone out (6.35mm)
  • Power socket (5.5mm/2.1mm) x 1

Why is power efficiency so important?  If it sounds good, I don't care how much power it uses.  And some of these designs seem to indicate standard opamps that run the headphone stage, not the T amp.

This I believe is mainly a speaker amp, with a headphone amp function for night time listening.

It's a well made amp for small speakers. I'm using it in my bedroom.

There is a chip near the headphone jack, but I cannot read anything on it. I guess it's an headphone amplifier chip.

A "T class" amp, i'm curious how well it drives high impedance cans. @Weiss, have you tried it with headphones?

The Tripath chip can't be used to power headphones (the common ground on TRS plugs would short it), so it is not in the signal path for the headphones. Like most Tripath-based amps, it uses a separate headphone amplifier circuit.

 

I do not have this amp, so I can't comment on how well it performs.

Small, energy efficient speakeramp. The general concensus is that the TA2020 model sounds best and is the one to get. Can be had for about $50. Should drive most efficient bookshelf speakers (86db) without too much hassle. I ordered the TP-22, based on the TK2050 chip. Slightly more oomph than the older TA2020 chip. 

 

These things are a no-brainer really. They're actually REALLY decent.

When it comes to basic speaker listening, yes they are. 

They are being used on car audio as well.

People have succesfully used these to drive orthodynamics as well. Check out this eye-opener: http://www.headfonia.com/hifimediy-tk2050-amplifier/

IMHO with speakers it is a decent amp. It drives my bookshelf speakers in my bedroom as well as my floorstanding speakers in my living room.

I've tried it with headphones once for a short time. There was nothing special about it but my impression was that the headphone out of my AVR (Marantz SR 5004) sounded better.

Im thinking of buying the TP32, Does anyone have any experience, good or bad advice on it?

Ill be using it as both a headphone amp and to run small speakers.
