Topping A90 failure issues. Should I try a 3rd A90?

I purchased the Topping A90 & D90 MQA August 2020. The A90 lasted about 3 months then "blew up" with major static in one channel. I tried different headphones, connects (4 pin XLR, 4.4mm pentacon) and it was in fact the A 90. Apos exchanged the failed A90 (took a long time) and after using the 2nd A90 for less than a month, the same issue. So after 2 failed A90's I'm wondering if I try a 3rd or another headphone amp? I'm using XLR balanced (and have 2 headphones that are also balanced cables). Thanks for any counsel.

Wow! they get raved about over at Audio Science Review and get second from the top honors. I’d try a third, could have just been a bad batch of one component.

UPDATE, thanks all for comments. I did in fact receive a 3rd Topping A 90 and it has been working so far. 

Enjoy the music!

The Topping DACs are excellent bargains in high end audio and good examples of how high end audio is not about price but intention.

I am now using a Topping pre90 preamp and I am amazed how good it sounds. It does not have any features other than inputs and volume. However, the sound is extremely clean with nothing added. Cost is $599.

My other preamp is the CODA 07x which cost a lot more and adds warmth to the sound. 

I am very impressed by Topping.
