Which IRS2092 board to choose

[jeeracing]

Hi, I just looking to buy an IRS board for bass dutie on a dual 68vdc. Even good on 4ohm and 8ohm

I'm looking for the best bass quality, lowest distortion and the best long term durability

I'm hesitate between those 3 pcb.

1- HIFI Stereo IRS2092 + IRF4019 Class D Power amp board 400W*2 ±60V--±70V | eBay

2-https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F191840227593

3-https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.ca%2Fulk%2Fitm%2F110961632456

I will like to hear you opinion and I'm open to hear any other suggestion too.

Thank you very much

I would probably go for this one:
Sure Electronics' webstore 2 x 750Watt Class D Audio Amplifier Board -IRS2092

Thanks, but, why that much power amp? I have a 600va transformer

Because of the high voltage and the IRFB4227 output mosfet.
The "lower" models are only accepting 60-65v max.

Sure have a 250w version who can take 70v. I think that version is enough for me.

I had a couple of Sure amplifier and the quality was always good

OK.
