Doh, my bad nevermind me!  I was looking at the Q switches... didn't notice the Shallcos below it for freq & gain.   Not sure what those Q switches are though!

Bite the bullet. Sontec MEP250C with Firlotte transformers(and not sure what other mods) in transit to me.

I found the UAD MP to be so close to the MP hardware and its gone...

Interesting to hear that the software massive passive is faring well against the hardware.

I recently bought a 250c and found the controls to be absolutely brutal, much worse than the 250ex.  Am in the process of having it's organs harvested and transferred to a new boxes with switches, will let you know how it works out.

[dietrich]

please keep us in the loop how it goes with the box change

[dietrich]

too good to be true...
the 250c....before popped into the chain..my noise is -90...
i put it in and -60....
trying to return it.
the sound still what i expected in a good way but the noise...

So what's the consensus on the 250C?  

Sounds good BUT

Concentric knobs annoy people (but API 550 is ok?)
Noise Floor too high at -60  (but an OCL/2 at -59 is ok?)

I just want to know if these issues with the 250C are fatal or only fatal when its on the 250C while being acceptable with other gear.

there is something fixable on this 250c that is causing extra noise. but the sound...yes not the control of the mastering versions ...main advantage with a 250ex would be the zero detent. concentric does not bother me at all...

still might return the unit if no help from seller on the noise issue....
if for tracking would deal with it. but once you get the meters out..

Is the rest of your signal chain balanced, unbalanced, or a combination thereof?  Try buffering it with balanced connections.

path is all balanced. I even went around mastering chain as well and plugged direct into the monitor controller as well. noise at the top end of frequencies.

maybe you want to swap it for your nseq-ff?

Something's wrong with that 250 if it's that noisy.

[dietrich]

I could use it as-is on most electronic mastering jobs here as long as I was not pushing it too much but that is not good enough....

Something is definitely wrong because I'm getting a noise floor of around -80dBFs with it routed through my Manley Backbone and my ADC full open (and I usually capture with about 3dB of attenuation set on my ADC instead).

Best regards,

[dietrich]

I have -89dBFs with hardwired chained all bypass. Popping gear in-everything in except the sontec I am around -87.
well... looks like keeping the sontec on now for hours ..somehow  at -83 now...

I am not going to question ...

Warm noise tends to rise upwards towards the ceiling, whereas cool noise falls down to the floor.

Much like internet forums, where hot air rises (and soon displaces all breathable air)
