Aiyima A07 Pro with 36V 5A Power Supply - Rs. 7,500



Gifted by a friend in Thailand. In OCT 2023. Initially used to test out old speakers in my house and then with a set of speakers I had built. Overpowered for my usage and so I decided to buy some TPA3116 boards. Dropped that project after I bought an AV Receiver and don’t need this anymore.

Includes Amplifier, BT Antennae, Power Supply
No Box, Bill, etc.

Nvarcher / Blenhance 2.1 DSP Board - Rs. 2,000

Purchased 3 of these boards from AliExpress to integrate subs. Works as sound card and can even apparently drive some headphones/earphones. One is extra after I purchased the AV Receiver hence selling. Board is unused. Just tested to check the stock functionality. . Purchased in the beginning of March 2024.

Includes the board, Button breakout board and potentiometer breakout board (YOU WILL NEED to buy POTS)
