看看国外对这个“炒鸡蛋”的评价吧,若有看不懂的朋友,我可以翻译。
Creek OBH 11 description is misrepresentation
This was taken from the description of the Creek OBH 11 at their website:
"No expense has been spared to enable the OBH-11 headphone amp to faithfully reproduce a music signal. Only the highest quality components are used in its classic amplifier circuitry, to achieve low distortion and noise, with good stereo separation".
No expense spared????????? erm I tend to disagree with that statement Mr. Creek. You have used the cheapest components available on the market in this amp and you want to revise that paragraph to:
"Expense has been cut down to the bone and we use the cheapest components money can buy in our classic amplifier circuitry to maximise our profits"
God, do these manufacturers think we don't know how to use a screwdriver and "never" have a look under the bonnet? I'll be contacting Michael Creek to ask him why My headphone amplifier didn't come with "the highest quality components" on board and arrived with "cheap crap" instead.
A blatant case of misrepresentation of goods if ever I saw one.
See the full write up on the OBH 11 by Creek here:

If any other OBH 11 owners here take a screwdriver to the unit and slide the PCB out (easy 30 second job) they will see for themselves that cheaper components couldn't have been used as these "are" the cheapest you can get!
God I'm fuming after seeing that description on the Creek site, I will be on the phone to them first thing tomorrow!
Creek OBH 11 Component Horror!
Had my Creek all of one week and can honestly say the headphone output from my audiolab 8000A amp does much the same job.
Time to get under the bonnet to see what was going on: After removing the screws and pulling out the PCB I had to go and get a beer to calm my nerves when I saw the cheap components that were attached to the board!
The largest capacitor was a "Samwha" 35v 2200uF and the rest were a mixture of "Nichicon" and "panasonic" caps.
After doing a bit of research here is the price list (UK) for the capacitors and pot.. the prices will obviously be cheaper for the manufacturer as they buy in bulk.
Samwha 35v 2200uF ?.11
Nichicon 35v 220uF ?.01
Nichicon 50v 47uF ?.03
Nichicon 25v 220uF ?.01
Panasonic 63v 47uF ?.09 (for 3 of them)
Alps Potentiometer ?.39
All resistors ?.25
Total: ?.79 p
I've got to do a "ball park" on the other components, including the case and power supply and reckon on around ?.30 which gives Creek and the middleman ?25 of profit to split between them.
I was "horrified" to see such crappy componentry inside such a well made little box and there is no need to employ such cheap stuff into a design. It's an example of cutting costs to the bone.
So you will be thinking the amp is going back to the shop?? No way!
I have ordered up some ELNA cerafine and Tonorex caps of the same values on the OBH 11 board and am going to replace the crappy caps with these which I am sure will make a HUGE difference to the sound. They cost me ?3.00 for the 7 capacitors so they have got to be better than the 25 pence Creek stock capacitors.
I hope to get the caps installed by the end of the week and I'll give them a further week to form (burn in) and will then come back and report on the difference, if any, to the sound. If good I will upload the full parts list and photos to my website so other Creek owners can have a go at upgrading to better caps.
For those of you in a hurry here are the ELNA part numbers you'll need:
ROA - 35v221MP9
ROA - 50v470MP9
ROA - 25v221MP9
ROA - 63v470MP9 x 3
ROB - 35v222MK8
Dunno about you guys but I don't expect to find capacitors costing one penny inside a Hi-Fi product. If Marantz can afford to use ELNA silmic caps in their budget CD players then Creek can do likewise. The only real part of this amp that leans toward "quality" is the case.. the rest of the components belong in the dustbin as far as I'm concerned.
I'm sure this amp will shine though when the signal is going through quality caps
