I just got the Matrix M-stage and it sounds good but unfortunately the treble is too veiled/muffled/congested in my system. How can I mod it for more open and extended treble? Thanks.

Thanks.
 
I just ordered the BURR BROWN OPA627AP WITH CLASS A BIASING MOD
 
(http://coolfungadget.com/store/index.php?route=product/product&product_id=91)
 
Should I have gotten the OPA627AU? What's the difference?
 
EDIT: I guess they are the same thing.
 
What about just trying the class a biasing adaptor for the stock OPA2134 opamp?

not worth the additional cost.

I got the OP627AP set in the mail today as well as the Class A biasing adaptor. Can I use this adaptor with other opamps besides the stock one? Such as LT1364? What might the benefit be?

So far my favorite opamp in the Matrix is the LT1364CN8. It even beats the OPA627AP mod that coolfungadget sells. Strange that no one recommends the LT1364CN8 for this amp. It is very clean and detailed and refined, to my ears.

you just unscrew the screws then flip off the cover.
