Hello all ASR members,
Recently we have launched a series of TPA3255 digital amplifiers, and we have also received a lot of feedback from audiophiles about adding high-pass filtering.
Therefore, we have done some research and designed an A5. The following are the functions and appearances that have been temporarily determined. Please take the time to have a look, share your thoughts and shape it together!
Here are some highlights of the A5:
1. With acrylic window design on the top just like our DAC-Q11.
2. Easy to switch the op-amps, just take off the acrylic window and no need to remove screws.
3. Three backlight colors can be displayed individually and also can be mixed freely: blue/green/orange, the color switch is inside the A5 but easy to select and mix from the window.
4. Add HPF filter, the range can be adjusted from 60Hz to 6KHz.
Here are some questions that need your suggestions:
1. What range of the HPF filter adjustment is better and suitable for most audiophiles' use?
2. What power adapter is better to match with the A5 considering performance and cost performance? Below is the estimated price:
A5 with 32V5A power adapter, $79.99
A5 with 36V5A power adapter, $89.99
A5 with 48V5A power adapter, $99.99
Which one do you prefer?
Basic Function and Parameters
Audio input: stereo L/R RCA
Audio output: Banana speaker jacks / 3.5mm AUX
Max power output in theory: 300W*2 (4 ohms, THD10%)
Frequency response range: 20Hz-20kHz (±1dB)
THD+N: 0.007%
SNR: ≥110dB
Working voltage: DC 24-48V
Of course, other suggestions are also welcome. Thank you for sharing your opinions in advance!
