hey sonyman.. that ppl really dunno make business. If u go Music by Design, Simon will give u try RS-1 lagi.. Nvm, i oso wonder AKG601 & AKG701 got HOW BIG sound difference. Only u can share the experience wif all of us here. Consider u haf listen to a few pair of headphones. U should be qualify to provide quite a reliable source for us.
Before u audition AKG701, plant the AKG601 sound signature into ur mindset first. To me, when u are doin audition in shop. Ur mind will going to have alot of placebo effects. If u think dat thing good, u will keep convincing urself How good it is. If dat thing got one issue(such as price or design or others reviews from somewhere) dat u dun like. U will probably keep finding excuses to reject it.
I not sure if this happend to anyone of us here.
Pcwork is right on the bass.. Bass impact listen longer will head dizzy.
Bass depth- makes music so alive. I enjoy the bass resonance.
Btw, i cannot tell How Good is AKG701 soundstage. U need to find out for me. i dunno How good is Hp890 soundstage as i dun haf one to study its performance for years. And i had listened to it so short while during gathering moment only.
nvm i will go to kelisa house for long long time to listen. no worry.
=P of course, IF he allowing me to go. hahha
here's interesting things i found in internet about K701

Whether you prefer the holistic approach or like to listen analytically, the K 701 will turn perception into pure enjoyment. AKG is the first manufacturer in the world to use revolutionary flat-wire technology in headphones, namely, the K 701. The result is a truly dramatic sound that places every musician at their correct location with pinpoint accuracy. This kind of agility, spaciousness, brilliant highs, and velvety, punchy bass is simply miraculous. These superlative open-back dynamic headphones provide an outstandingly accurate sound and excellent imaging. Try the K 701 and find out what ingenious headphone engineering can do for you.

first i were wondering, how they manage to make a diaphragm sounds so even in all frequency, as we know the physical characteristic of the plastic / mylar / watever membrane has a nod point... =P
but hell they are cleaver to make the diaphragm into different thickness to eliminate the sound resonance problems, and increase accuracy. not sure about other brand though. but this really impressed me. even though i haven't heard it. and i am quite a noob in physics..
and this really deserve a huge successfull. rather than just blindly upgrade the magnet gauss and decrease the voice coil weight / changing in membrane material and then slap in a new model then selling it higher price.
as far as i remember, HD650 has a driver which has a big hole in the middle, hence the air pressure is balance, membrane can vibrate faster. and the duofole to increase the rigidity of the membrane... cool things.
