I think the cheapest PCIe card is the
EMU 1212M
(currently £119) but given you could spend a bit more money and get full desktop/laptop
flexibility then I don't see the point in compromising on a PCI card.
The
portable device that offer the best value would be the
Focusrite
Saffire Pro 24 (currently £199) but thats firewire which is on its way out as a
standard.
A more future proof USB version would be the
Focusrite
Scarlett 18i6 (currently £239) but I guess this is a bit wide of the mark of a simple
low cost interface that just offers ADAT.
My killer recommendation would be the
Presonus
AudioBox 1818VSL (currently £389). This offers two way ADAT which means if you
wanted you could flick the Audiobox to output through all channels and have 16 separate
channels of audio to mix. Obviously you'd need a large analogue desk and that'd be a
pretty specialist application.
The Presonus AudioBox 1818VSL would give you the
best quality and if the price tag is a bit much then sell the ADA8000 on eBay and utilise
the superior Presonus preamps. Obviously if you have other uses for the ADA8000 then
thats not going to work.
