I see it like this, money is not free....
Is there any consensus already of what capacitors one could change for a better sound?
Something like smoother highs, more articulate bass and mids, instrument separation, etc...?
2 - My one question for M-Stage owners - "IF"? I wanted a slightly warmer presentation with my k701s... I have the class A OPA627 upgrade in - I have some Opamps on hand...incl LT1364, LM4562, and OPA2107. What would you suggest for my k701s - if I favored a bit of a warmer feel?

Definitely not OPA2107 = controlled bass and bright. I love using this opamp with an output stage that is slowish and warm.
LM4562? (more it gets pushed into class A, the warmer it sounds). OPA627 pushed into class A sounds brighter. This only applies when using resistor mod on the Matrix. I actually think the LM4562 and OPA627 have a sound balance that converges with light class A biasing.
I disagree with folks who say LM4562 sounds bright. I've had at least a dozen of of those chips (purchased directly from Digikey) that I've modified and sent off to other head-fiers. LM4562 even without class A mod sounds warmer than stock OPA2134 (and I've got a dozens of those sitting around too for other projects). YMMV.
JRC4556? It's warm all right!
I'm just posting for 2 reasons:
1 - those who follow this thread - which is slanting to a "now it's time to sell the M-Stage for the next big thing" OR the "the FOTM hype was off and this thing just isn' what I thought it would be" posts...I bought the M-Stage very early on - I'm not a hype freak. This amp is flat out married to my k701s - not even a question. I would sell the k701s if I didn't own the M-Stage. Just saying - they are beautiful together - I've a/b'd against the LD MKIV which I am a HUGE fan of and the M-Stage is the huge winner for the k701s

anyone knows what caps i can replace the pair near the opamps to make this amp sound darker? mine is elna.
or should i change the 2 big power caps instead? also elna.
im kinda done playing opamps, and dont want to change them, or topology of the circuit.
i just need it to be darker sounding overall. im using lovely cube tho, but same mod should affect should apply.
Thanks to my dear friend Mike, I got a M-Stage for a loan and I immediately took it for a ride with the Audez'e LCD2. Plenty of power, no problem for the LCD2 as it is able to drive it quite effortlessly. The M-Stage is no β22 for sure but I still like it.
Well, after a while I noticed how the sound was a bit too distant with the class A-biased OPA627 so I swapped it with a personal favorite of mine, the cheap-but-amazing-sounding OPA1642. Well, the first thing that I notice is the sound is no longer distant but now a little bit forward, just the way I like it. However, this doesn't do high as well as the OPA627 as for example, cymbals now lack shimmer and air. Overall the sound has become a little bit darker and more forward.
