The bass of 1a is sometimes too booming. The house of 1adac is smaller than 1a and the air hole is also smaller, thus the 1adac has tighter bass and less quantity. Result is 1adac has more balanced sound.  What's more, let's compare the DAC/AMP/Battery part of A17 and 1adac: The weight of 1a...

I have walkman A17 +mdr-1A with MUS-S12SM1 cable for over a year now. The A17 is filled with loss-less flac files and some hi-res audio. Last week I went to a sony store and tried an 1adac with my xperia z5p. Although I only have 256kpbs ACC in my cell-phone, 1adac has impressed me a lot with...

Yes u can

Well~open cans are opened at the side, not on the top~ besides, they are all equipped with filter, not a 3mm hole.   In a new product salon last year, Mr. Koji Nageno (ソニー株式会社 パーソナルエンタテインメント事業部 ヘッドホン技術担当部長 投野耕治氏, Sony Corporation Personal Entertainment Division headphone technology Senior...

Thank you. I’ve opened 1A last night and made a quick comparison with CD900st. It is said that Sony has taken some ideas from CD900st while designing 1A.       This is measured by my cell-phone with the SPL Spectrum APP, not precise but shows the basic situation. 1A is the red line and...

Could you please show some pictures of how to remove the pads?

1r pads has better performance than beyerdynamic velour pads in mid-range. Actually the most significant change is bring by Furutech cable.

This is my CD900ST, with mdr-1r earpad and foldable mode. I've tried z1000 cable but Furutech ADL iHP-35 is way much better in both bass and treble quality. Also the better cable can improve resolution greatly.

The blue TPS-L2 in Guardians of the Galaxy really grabbed my eyes.

This is the blue A17 with CKM-NWA10 soft case I bought last week. Mainly using it with a modded CD900st cause warm A17 and cold CD900st is a good combination. All the EQs are closed to give bigger dynamic range. It is very suitable for vocal records. I went to a solo concert of Angela...

Would this be Sony's balanced plug for new flagship? [http://bbs.imp3.net/thread-11179547-1-1.html]

New pictures

Got no further information last week. However, my wife have approved my plan of buying new Sony flagship. 

I bet these information are real. It's been 'confirmed' by a well-known 'Sonyboy' in China. http://www.loxpo.com/forum.php?mod=viewthread&tid=448 In addition, 50mm version will have a ringlike transducer to improve bass quality, i.e. two liquid crystal transducers in 50mm version.
