Hello all ASR members,
Last year, we got inspiration here and we released the A5 amplifier with a high pass filter based on all your opinions.
We are happy to let you know that it is very popular, it is your valuable opinions that made it available in such a short time. On behalf of the Douk Audio Team, we want to express our sincere thanks to all of you.
Now, we collect some ideas in the A5 thread and from some A5's users and decide to design another amplifier with both HPF and LPF. If you have any other suggestions please feel free to leave your ideas and we believe that your valuable opinions will help create another popular amplifier.
Here are some initial thoughts not determined yet.
1. Chips: TPA3255 or Module design (Purifi/NCore/Infineon)
2. Inputs: RCA and XLR
3. Outputs: speaker jacks and AUX or RCA (SUB or Full-frequency)
4. With volume control and support bypass
5. With a high pass filter to control (with scale value) the main speaker output
6. With a low frequency filter (with scale value) to control the main speaker output or AUX/RCA output
7. With 12V trigger input
8. With loudness adjustment
9. Internal or external power supply
10. What is the acceptable selling price?
11. The chassis may be bigger than all the TAP3255 amplifiers we sell now.
12. We may create the matched DAC/Preamp with this amplifier in the near future, any advice on them?
Thank you again! All suggestions are welcome!
