First off,one has NE series from BB(TI) and the other has LM series(which Jan highly acclaime it before he turns to the op27 series from BB) from National Semi. And Yes!!!!latter is better Opamp than former in spec. as well as sound... but biggest diff. is A-class operation through current biasing....It really does makes diff. in sound. I just hope you are capable to understand what I'm talking about..and If you really think it's the Opamps that change all that diff. in the Amps. then I introduce you to the heavens of All the opamps. Try TI, AD, and NS...
Under several bucks, you can experience almost every Opamps they put on the market.....and you know what~~ you can even ask some samples from them for free of charge...ain't that neet~~~~0.......!!!!
secondly, If you purchased the Creek, then you know that it's been on show-windows of audioshop in the shoppingmall long enough before they start advertizing this on the web or megazines....I have no idea why they do this kinda rather unusual tactics about this product on the market, but anyway I did have chance to have a good look and listening, quite a while ago, through arkam72t and HD600 w/ DIY-silver intercable combination which shop owner set it up for promotion wise.
And My impression was just THAT!!!! I described before....
Probably it just me~~though... Anyway as the some comes to say: judging the sound is totally subjective and everyone is entitled to it....I judge it on my point of view. and NO emotion or hard feeling involved.... Obviously you seem very involved..though....
Thirdly, Have you ever tried other Amps???.....at least like META42???
which I believe it's way step ahead and superior in every aspect....to the OBH.......
If yo didn't~~~ then I suggest you go ahead and try One... It's not that expensive either......
On my experience, even though, more or less there was subtle diff. in sound, META42 was META42, CORDA was CORDA,and OBH was OBH,,,,,,, no matter what Opamps I swapped around.....
Por ultima!!!! I believe this is good enough answer fo ya !!!! and I think I've done my job.... So I'm really done w/ this thread.... No point doing this any more!!!!! So!!! go ahead~~~troll on~~~
cheers
