Hello,
Iv'e already buyed hifiberry dac,and it is very good.
Im intersted to buy hifiberry amp, but i've no good impression with other class d amplifier as:
- ta-2024 (tripath)
- Tripath TK2050 Hifimediy T1-M
I ask you, your impression of sound quality of Hifyberry amp compared with two tripath amp in up.
If the sound of Hifiberry is similar a classic old transistor b class i buy it. :)
Thanks and regards,
Mauro

HiFiBerry team Hi Mauro,
sound quality is very subjective. We're happy with the sound, but I can't guarantee that you will like it. If you are not happy with other Class-D amplifiers, there is a risk that you also don't like the HiFiBerry Amp.
The best option we can offer you is buying the Amp and sending it back if you don't like the sound. In this case, we will refund the money for the Amp, but not the shipping costs.
Best regards

martin cotterell Hi folks ... Can anyone point to any guides to installing & using the amp?
- presume headers need soldering in the same way as the DAC?
- what are the specs for the power supply? -
HiFiBerry team Dear Martin,
yes, you need to solder the P5 header exactly like for the DAC or Digi board.
The Power supply should be 12V/3A or 18V/4A with a 5.5mm barrel connector.
Best regards

martin cotterell Eventually found time to try the amp today - but having power issues.
Header soldered but no power getting through to the Pi (no lights, zero volts on TP1-TP2 on the Pi). Pi Ok (works fine with Amp unplugged).
Next tested the amp sat unplugged from the Pi >> not getting 5V on any combination of the 5v & 0v pins that the Pi uses (checked against the Pi pinout) -
HiFiBerry team What power supply are you using?
Best regards

martin cotterell Using a (good) bench top variable voltage DC supply ... Tried connecting into both the terminal block on the amp and into its socket.
With no other connections onto amp (no speakers connected or it plugged into Pi), I can't see that amp board is generating 5v (testing on 26pin connector) -
HiFiBerry team What voltage did you use? Are you sure the polarity was correct? The Amp has no protection against wrong polarity. I think, we have to test the board here.
Best regards

martin cotterell Daniel ... Started at 12v, but also tried increasing to 15v. Polarity double checked using multimeter. I will post amp back to your Bachmattstr.14 address. -
HiFiBerry team Dear Martin,
declare it as "defective return" with a value of €20. We will check it here.
Best regards
Daniel
