Bottom Line:   
This is a simple, straightforward, no frills unit. It is a substantial improvement over most of the built-in headphone amps you will find at this level. I have two of them: One on my main system; the other hooked up to my computer. My headphones are Grado SR-125 and Etymotic ER-4S.

Bottom Line:   
A good amp, with silent noise floor. I found it to be too bright, lacking a bit in bass and lower-midrange. This made the sound 'distant' and somewhat cold and uninvolving. This _may_ however be due to the absolute P.O.S. interconnects I was using with it (that came with my Panasonic F85 DVD player). I don't know, as I have no mid/high-end interconnects to experiment with.

The sound is very clear, it does pretty much what you expect it to: make sound louder. I bought an Elpac linear regulated PS for this, which I found made the soundstage clearer, quieter, sharper. Not bad for $40 USD. This made for a noticeable improvement with ER-4P headphones, which are super-detailed, to a flaw almost.

The Elpac is not a drop in replacement for the PS the OBH-11 comes with however. It fits, but loosely, occasionally cutting out power to the Creek. I purchased a properly-fitting plug from an electronics store and my dad soldered it on for me. It then fit perfectly snugly.

When paired with my etymotic er-4p earphones there was a great deal of detail. The brightness I spoke of earlier I attributed to the ER-4ps for the longest while, before purchasing a Panasonic XR25 receiver and plugging my headphones into that. The XR25 has poor headphone out, due to persistent and annoying noise through the headphone circuit, but even with that, the sound was warmer and much weightier than the sound from the Creek. The soundstage was once again enveloping my head, instead of staying at a distance.

The OBH-11 is good, not great, certainly not amazing. For $100 it's a good buy; for the $299 or so it retailed for it would certainly not be worth the money IMHO, considering all it does, the cost of parts, and the fact that this is not God's gift to headphone listeners.

I give it 4 stars because I paid $100 for it; had I paid twice or three times that amount, it would get 3 stars.

Bottom Line:   
The Creek OBH-11 (non-SE) is a great little amp -- with the right power supply. It just sounds terrible to me with the OBH-1 PS it comes with, and incredible with a 24v Elpac linear regulated supply (which is very close to the OBH-2, and about $70 cheaper).

Bottom line -- if you get this, throw away the cheap Chinese wall wart it comes with and buy a Creek OBH-2... or check electronics parts stores online for Elpac model WM080-1950-760 which is nearly as good and a direct plug-in replacement. It's almost a brand new amp.

Bottom Line:   
Wishing to listen to music after the family had gone to bed, and not being happy with what came out of the headphone circuits of my amplifiers ( Yamaha HT and Revox) I looked around for a dedicated headphone amplifier, finally settling for CREEK due to reputation, reviews ( eg this site)and cost. I didn't get the overpriced power supply, but instead I use one I got for a quarter of the cost through the local electronics supply shop ( JAYCAR for those in OZ)which is regulated, gives 1000mA and has a good reservoir capacitor - and it works great!

The amp works well with Sennheiser ( 570's) and Grado's , clean and detailed soundstage, little sound colouration or distortion, and excellent dynamic range. In summary it proved the good, cost effective solution I was looking for. However I wouldn't go as far as describing it as "audiophile" quality, for $$ more there's better out there ( no I'm not referring to STAX's).

I've since got a NADC320BEE amp ( excellent!!!!!) and the headphone circuit is significantly better than what I get out of the Creek - all that from an integrated costing about USD 100 more than this unit.

But if you are in the market for a good sounding, well built headphone amp that will drive a variety of headphones with no fuss go for the Creek, you can't beat it for value. Get a good power source and good interconnects to get the most out of it.

Bottom Line:   
I was looking for a headphone system as I spend many hours on the computer and found it inconvenient having to "either" go downstairs to listen to music in my dedicated listening room or stay upstairs on the computer without any music.

I had contemplated positioning the computer 3 metres away from my hi-fi, facing the speakers, in the classic "centre stage triangle position" but thought this a rather bizarre set up. For one thing, the ambient noise of the computer fans would mask much of the detail... It's all very well having a dynamic range of 90dB or so on your CD player, but if traffic, the washing machine, the computer or just general household noise creates a background level of 60dB or so, much of the quality will be lost. Some say that music sounds better at night... probably cause the ambient daytime crap has gone to bed!

I therefore decided that "in head" sound would be the best bet and boy was I right!

I've had this Creek amp up and running for 3 days now and it is getting better day by day as its circuitry burns in.. I could hear a slight buzz from the amp for the first 24 hours (probably the capacitors charging) but this has now disappeared.. a sign of just how revealing this unit is. It "will" reveal a lot of the source but will also reveal itself through the phones during the burn in stage.

3 days listening and I am VERY impressed... so much so that I can't concentrate on writing a review such is the quality of sound (listening as I type) so if this seems a bit "bitty" blame it on the Creek!

Will write an extensive review (headphones off so I can concentrate!) once I have fully auditioned this unit.

So far, so good. At this stage I really can't see what value could be gained from a "regulated" power supply.. I'm in the process of building a 24DC 250mA regulated PS so will report in my next review. I will upload a circuit diagram of my power supply to http://freespace.virgin.net/rock.grotto once it has been designed, built and tested.

My impressions after only 3 days though are "a seriously neutral amp"
