D/A for external mixing on a Mix system...

[Seeee]

The 888/24 has 20 bit converters on the D?A. the 888/18 has 18 bit on the D/A as well as the 888/18. the 882/20 has 20 bit d/a

my question is.....

is it gonna make that much difference on the d/a to justify another 888/24 thats only gonna get me 20 bit d/a anyways?

I have 1 888/24, one 888/16, and can pick up 882/18's for 100 bucks or so. 882/20's for 300, 888/18's for 300-400, and 888/24's for 700-900.

right now I run the drums to the 888/18 and the rest to the 888/24(20). just wondering if the 888/18 is that much better than an 882/18 or if the 888/24 (20) is much better than the 882/20

basically the 882's are still balanced units on TRS.

I need to finalize my d/a and get my 24 tracks of mixing on the console going.

adat 24 bridges are getting cheap but converters are still expensive so I know whats best but I am on a small budget and the last 6 months of work has been dead. so here I am trying to spedn more money. go figure.
