There are only so many combinations you can have... and with there being an extra op-amp, and more / smaller caps on the 21, let alone different resistor counts... and a different PCB layout... i'd say thats different?!

I believe it's illigal to get the schem. and actual wring diagram
our in the open to public w/o permit of Creek.
So I won't do it before I get reconfirmed on the matter.
But it doesn't take rocket scientist's eyes or brain to figure out
it's the same thing.....I bet anyone spend time w/ soldering kit
will tell it in a snap!!!!!!

For fun!!!!!!!!!!!Here is another Pic . ya all want!!! "obh11se"



If you feel any increase in resolution in sound of brand new obh21se......
that's because they get rid of those MOSFET......which they used a lot during 1980~90's and replace it w/ Opamp..... But I still like those kinda out of fashoined parts(MOSFET) though.......
Gee~~~Is there anyone out there starting to think that obh21se is downgrade!!!!!!..... ????

hi, all of head-fier,
i also have a creek obh-11se, but i check the serial no' of this amp, i found the serial no without the "b". i think my obh-11se should be "rev. a". and i also open up the enclosue of obh-11se, the inside of obh-11se is much better than the new comer obh-21se, but not as good as the "rev. b" obh-11se.

Considering that in an ideal world an amplifier should be as minimal as possible to avoid interference... no...

But, this is my very last post on this... I'm very bored with the fact that I have to keep defending my purchase when it appears that I am the only person on head-fi thats heard it...

If you hear it, and you think it sounds like crap... thats fine ~ but to say its crap, just by looking at a PCB???

I'm no junior genius, but they don't look THAT different to me. I'll be interested to hear if they really do sound any different/better. I always thought that the old Creek 11SE was a pretty nice amp for what you could buy it for used. The new price was a bit, well, pricey.

No ~~~It's original as it is~~~Jazpresso

Yah~~~~~I get bored and I'm done too!!!!
And I never attacked you but Creek.
and there were some folks wanna dig the secret of this
product. so I felt like leeking a little info. That's all.
I never meant to hurt your feeling.
And I heard it and it did sound like crap.
If that was good I would've mentioned "goldmund" and
compared w/ it. Talking about How the hell did they achieve that kinda
quality w/ that simple setup????.........something like~~~!!!

cheers

no, i heard there is two versions of obh-11se, there are the early version "rev a" & the later version "rev B", i have the "rev a" on my hand, and i saw this argue about the creek, so i opened my creek obh-11se and see what it is, my obh-11se seem not as good as ur obh-11se, but better than the new obh-21se.
sorry that i don't have a dc. if i had, i would take a photo for u to see.

Yeah~~~It could've been great, if I can see that pic.
I believe this one is latter, new rev., of obh11se......

What op-amps are in the original models?
post #43 of 89
The OBH-11 uses an NE5532. The OBH-11SE is all discrete -- no op-amp.

Pretty much all headphone amps look just as simple in design or even simpler. Yes it is amazing how much you pay. That is why I am going to start getting into the DIY stuff.

duncan,
i had a chance to audition the obh21se at the seattle head-fi meet. it is a fine amp, but with my headphones i prefered the warmer sound of radrd's meta42. i hope you don't think i am bashing your purchase, this is just my impression.
