Cool story bro, yeah before I'm settled with SA5000 and CD3000, I wasted the CD1000 and CD999 first.
SA5000 sounds "partially" similar to CD3000 because the SA5000 is the "last" pinnacle development of the porous biocellulose diaphragm.
SA5000 diaphragm is made Silica/PA66 (Sand/Plastic) Nano-composite material, the nano synthetic imitation and improvement of the biocellulose porous structure,
Sad that with Z7 they stepped back to Aluminum coated Liquid Crystal Polymer (metal/plastic) drivers.
My first expensive "highend" HP starts with CD999 with amorphous diamond coated plastic diaphragm, the forefather of biocellulose drivers.
It sound the "best" at that time to my inexp. ears, but the cups were too tiny, not angled and cramping will hurt my earshells.
And after few year or so, the lousy plastic hinges broke exactly in the of the "C" by hair fracture cracks.
Then the CD1000 with biocellulose dia. came alone, however I wasn't happy with the inbalance of the drivers sounding differently.
So I opened the cups to find the horror, 1 driver isn't the white biocellulose but the lousy x coated plastic dia.
Returned for exchange, after a week got the 2nd pair, however I wasn't happy with the pierching harsh treble.
So I DIY hold the drivers above the damp of cooking water to "soften" the porous dia. and it worked.
Pierching treble is reduced to very good sounding, however after few week, 1 driver died by losing the glue joints of the coil, ouch.
Because the CD999 drivers have exactly the same 50mm size and form, so I put those in CD1000.
Sound alot muffled because its missing the vibrant transients of the porous biocel.
I got a brandnew CD3000 with HP case (after the SA5000) for only $180 from online outlet store, I guess they didn't knew the CD3000's value.
CD3000 (casing) sounds alot better than CD1000 despite having "same" drivers.
Yeah, I think the SA5000 driver popped by an ON powerspike of the non-muting headamp, I'm doing (un)plug the HP everytime now to be safe.
They both shared the "airly" transients because of the porous dia., my SA5000 sounds best/better than CD3000 with headamp and after the "closed" mod by adding a vinyl piece to cover the "open" backcup grill.
CD3000 has a more wider/spacious/distant soundstage but the bass is looser and bloomier, I use it mainly without headamp because sounding best with portables media/nds/psp/music keyboards etc.
No, I can't mistaken them, SA5000 is the best comfort to me also, its lighter 260gr vs 380gr but CD3000 is better/warmer in the winter.
Yeah, I'm done for now untill these HP die someday.Edited by cdsa35000 - 1/8/15 at 9:35pm
