Noticed quite a big range of these full sized headphone amps now on mp4nation any reviews or opinions on them ? heres the specs of the top end one
 

Topping TP41 Class T Digital Amplifier & Headphone Amplifier

 
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:

1. High power (25Wx2).
2. Dual input
3. Very high efficency (88%).
4. "Audiophile" quality sound.
5. Speaker protection circuitry.
6. Headphone amplifier built in.

Specifications:

1. T-Amp IC Tripath TA2021
2. Output Power 2 x 25W
3. Signal-to-Noise Ratio (SNR) 98dB
4. Dynamic Range 98dB
5. IHF-IM Distortion 0.1% @ 1W, 4ohm
6. THD Distortion
7. 0.05% @ 13W, 4ohm
8. Power Efficiency 81% @ 25W, 4ohm, 88% @ 13.5W, 8ohm
9. Input Sensitivity 200mV
10. Dual RCA audio input jacks
11. Speaker out ( L & R)
12. Headphone out (6.35mm)
13. Power socket (5.5mm/2.1mm) x 1
14. Power Indicator (Blue LED)
15. Power Supply input DC 12V~13.2V 5A
16. Measurement : 145 x 60 x 240 mm
17. Weight : 3kg

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? 

 

[ardgedee]

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.

 

[Paul Graham]

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.

Hi guys,
I'm seriously considering this amp for the offfice (deskop).
Has it been reliable, particularly the connections and the potientiometer ?

 

[estreeter]

Given some of the incredible Youtube vids of smaller T-amps driving big speakers, I find the TA2022 a very interesting proposition.

Topping TP-60  50W into 8-ohms. There are still one or two entry-level fullsize speaker amps that dont manage those numbers - granted, if the first Watt is no good yada yada.  Still - for that money, you arent mortgaging your house to find out. These amps dont measure terribly well - fwir - but thousands of people seem to enjoy what comes out of their speakers.

I have two Topping TP22 amps, one for bedroom and one for office. They are built well, and sound smooth and clean. I have used 10 different integrated amplifiers under $1000, both solid state and tubes, and the original Sonic Impact T-amp as well. TP22 is good enough to be called entry level hi-fi and good enough for speakers under $1000. Bette sound than the original T-amp and much more power, too. TP22 has similar power to my Jolida JD301  hybrid amp, but better sound. 
 
I did not try the headphone version TP41 and we know that Tripath chip cannot drive headphones with a common ground. I wholeheartedly recommend the 30W TP22 for any audiophile who wants to save money for better speakers.    

 

[CaffeinatedX42]

I have had the TP41 for a little over a year now and enjoy it quite a bit with speakers.  I was actually shocked at how good it sounded driving my ancient (~1991) Bose bookshelf speakers I bought way back in highschool.
 
I use it in my mancave/workshop.
 
The headphone amp portion, though, is not very good.  Certainly for the money you can do better.  It is barely able to drive my HD650's and is, IMO, under powered.  It uses a separate amp circuit to drive the headphones and the speakers so you aren't getting any "T amp" benefit when using cans.  My Fiio E9 did a much better job with headphones.
