modding Matrix M-stage

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.

Search for Matrix and mod and you'll find all kinds of info. In the mean time https://coolfungadget.com/store/index.php?route=product/product&product_id=82

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?

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.

try OPA1641, this one rocks my world...and yes, my previous fav. was indeed LT1363.

Is taking the top cover off as simple as removing the four screws and does it lift off or slide forward/backward?

you just unscrew the screws then flip off the cover.
