Did you perhaps forget something?

I would greatly appreciate your feedback and any issues you see with Amiga content.

A1000 was great at the time, but surely it didn't have "512MB of memory"? ;-)

"resolution of 640 x 400 bits" that should probably be "pixels" ?

"sampling rates of 44,000KHz" should probably be "44kHz".
Also, while it is true that in theory even A1000 might have been able to generate 44kHz audio by poking paula with CPU, the original 68000 surely wasn't fast enough. DMA-able playback of >28kHz became available with ECS Denise (though you will need a multisync monitor or will lose the display while playing). [EDIT] It was available before AGA already [/EDIT]

"Jay Minor" should be "Jay Miner".

A2000 does have some ISA slots, but those are passive (only power and ground). You need a bridgeboard to enable the slots.

A1000 had HAM from the start. The feature missing from the very early (US & Canada) A1000's was EHB (Extra-Half-Brite).

Well, okay full ECS chipset can display double horizontal display frequencies (~30kHz) I guess. If you don't have a multisync monitor you lose the display while playing, though. So indeed then it is possible with DMA with ECS too.

It is possible to get >28kHz by poking the sampledata directly with CPU, but I still doubt 68000 alone can do it (at least if you want to play 16 bit samples with the 14bit paula audio trick).

However, I wanted to point out that stock A1000 surely wasn't able to do it.
