english hiya

my unit died fireface 800 - about a month ago
there was a blown out#4 ( ... ) opamp and caps

fixed

now i see the 2200μF on the psu are not looking so great...

i will get those... later-soon-ish

but the question is - i am looking at putting in more opamps
and
i am really looking for places where it would be a super bad idea
( as opposed to just not really necessary ) to replace opamps

Shirley;

The outs could use better stuff and . the ins too
but
im really just looking for red flags

On the input stages on these we use High Performance Burr Brown opamps for a warm punchy front end with excellent response and musicality.
On the output stages and headphone amps we use Linear Technologies opamps which offer a very flat response.

A Power supply modification was also performed for maximum bandwidth and to accommodate the additional Current draw from the new Performance opamps.
This includes a whole new power supply
