What are the "differences" between these Two and which is better suited for me

Also both use the OBH 2 Power Supply, correct?

Hi DrTacoElf!

The power supply is the same (OBH 2) for both modifications.

New 21 SE is silver colour, thicker front plate 5mm vs. 3mm.

The case is deeper about 50%.

It was made as new design line, according to Creek's website.

Pot is the same, input RCA and output jacks too. Even the led is the same!!

Soundwise, I think it's identical to the newer OBH 11SE rev. B model.

Hope that helps.

Your
Moonwalker

Hmm you mean the OBH 11 SE?

Also i though that the OBH 21 SE was an op amp design, where as the OB 11 SE was discrete. Could someone please explain the difference in those to me, and isn't discrete better

Moonwalker,
I see you have auditioned both the OBH 11 SE Rev.B and the OBH 21 SE. Can you please post a review? Can you better describe your experience and list the equipment you have used as well as music tracks you've played to compare the amps with?
Thank you,
Alex Altorfer

Hi Alex!

Sorry... no, I just read about it on the Audio Magazine in Czech Republic. The sad thing is, even the 21 SE version is probably not in class A operation. There seems to be one board inside the 21 and 21 Se amps. The only difference is some place left for more components in the standard 21 version (and smaller PSU). Both seem to have nice Alps pot. The S/N ratio seems improved according to Creek's papers and the THD seems lower because of feedback used. The 11 SE seems the only one vith discrete transistors and pure class A operation in Creek's line of headphone amps.
