My NFB-3 arrived today so naturally I played around with my office desktop setup instead of actually working. I have the NFB-3 feeding the m-stage to K702's. The stock Matrix opamp is OK and the OPA627AU class A mod from coolfungadget sounded pretty nice but not perfect. I then gave the 2 channel TLE2141 class A module a try from the D10 topkit and now I cant get the grin off my head. To my ears its perfect.  Worth a go if you have one!

Nevermind figured it out. Just another bad opamp from Mauser. Damnit. Anyone know if they have a return policy that's worth anything?

They should.

I'm a bit of a basshead and was wondering which opamp for my Matrix would provide me with a discernable increase in bass quantity and rumble over the stock chip. I've got a pair of Ultrasone Pro 900's and liked the rumble coming out of my portable XM4 w AD8620 op but the M-Stage is clearly superior in every aspect in terms of SQ, but miss the rumble.

Hi Guys,
 
I know this is stated somewhere in this thread, but I haven't got the time to look for it.
 
What is the recommended gain setting with k701?

can someone help me?
I just got my matrix m stage. whenever i change my gain, my left side will always be much louder than the right side.
The sound is only balanced when i use the default gain.
the other 3 gains will result in louder left side.
 
My setup is foobar --> X-fi Forte lineout ---> Matrix M stage --> K701

Do you have both sets of dip switch set exactly the same? If they are you might have a bad set of switches.

 

[jeff119]

omg. thanks. 
I feel so stupid right now!.
 
but i have one slight problem.
My pc will detect my left channel as right channel and right channel as left.
so i have to swap my rca cable with the red cable into the white jack and the other way round. - -
 
 
Anyway, how long do i need to burn in the amp?

10 or 18

You probably should have gotten a KICAS Caliente and an upgrade PSU to go with it.
You could try 2x HA3-2525-5 on a 2x1 socketed adapter, but it won't be that much of a difference.  You would have to also replace the output and opamp capacitors with Elna RFS equivalents, I imagine, for a bit more bass.

hi, besides | frank | who uses 0db gain with the lcd-2, are there other people who paired the lcd-2 with their m-stage and what gain do you use ?

I'll be receiving my pair at the beginning of this week and hopefully experiment with different gain settings and report back here.

Hi there,
 
i want to inatall the OPA627AU class A mod from coolfungadget. Is it difficut to install or just "plug and play"?

[castlevania32]

it's plug n play, even an 8 year old could do it (just be careful that you plug it in the correct sense, and AC deconnected, but this is obvious )
