I'm not trying to frustrate you, just flushing out the benefits and downsides of one over the other. There appears to be a slight advantage with two A7 monos over a single A7 mono, but that might be some cognitive bias on my part. If we are looking at the best savings model while still getting to get nearly identical performance while doing dual mono I'd look at the Fosi Audio V3 dual mono combo offering for $280 on Amazon. Only issue I see with the V3 is the lack of a 12v trigger. https://www.amazon.com/dp/B0DQ8FR9GH/ref=sspa_dk_detail_2?psc=1&pd_rd_i=B0DQ8FR9GH&pd_rd_w=AQonf&content-id=amzn1.sym.9bd45040-31dd-4792-bd5a-341290ebe305&pf_rd_p=9bd45040-31dd-4792-bd5a-341290ebe305&pf_rd_r=HCH8X9MEFSFR7FA8E1XE&pd_rd_wg=01I21&pd_rd_r=a1a0fc51-cb39-405b-a006-134ca5cd315f&sp_csd=d2lkZ2V0TmFtZT1zcF9kZXRhaWxfdGhlbWF0aWM edit: I don't know why I assumed the mono and stereo models of the A7 would be closer in price.
