    Sennheiser HD600 audio driver replacement

    The replacement driver finally arrived today. I ordered it through the Sennhesier web site last Thursday. It has a white screen which is different from the original one. Well, it's now in burn in mode. Hopefully it will pair well with its twin. My initial impression is good so far. Many thanks...

    Sennheiser HD600 audio driver replacement

    It was a bad day. My HD600 right headphone went wrong, there was no sound coming out from it. I opened the driver to try to fix the loosen connector and the connecting wire. The wire was so thin that I broke it. I tried in vain to fix it but no success. I tried the Sennhesier website to find...

    Little Dot MK III: An Exclusive Review (56k warning!)

    Penguindude ... Great review and very informative. Many thanks. Yang is offering a similar version MK IV (SE) except with a different tube set and components that he calls a special edition. Wonder how it will sound in comparison with MK III in your opinion? I'm seriously about the MK IV...

    C&C Box XO

    Clarity and transparency is what I am looking for in a good amp. It has to do with the architectural design of the amp circuit, and that is what Xin has been working to improve upon in the SM family ever since its inception. As of now C&C scores better in that regard in my judgment. Opamp...

    C&C Box XO

    Hi, mrarroyo: It's AD8616 the default opamp that came with LE. I haven't tried other opamps yet. I am hoping Xin will finalize his latest design and comes up with an upgrade plan soon for LE. As of now, C&C XO is my favorite that plays particularly well with K-501. However I miss the full and...

    Any Good MP3 players with an SD slot?

    For no reasons, I now have a good collection of MP3 players. They are: MPIO FL100, Rio Forge, Coby MP-C741 and Sansa e140. They all run on a SD card and a AAA battery cell. Well, not to mention my beloved players: iRiver H-120 and iPOD 5G that are all Rockboxized, Rio Karma and recently a Rio...

    iPOD 5G: Rockbox has better sound quality

    I did a headphone-out and line-out SQ comparison on my IPOD 5G with Xin SM3-V3 headamp and Sennhesier HD600 a few days ago and found no perceivable SQ difference. This has been confirmed and discussed extensively in another threads. I found instead a better SQ on Rockbox than the Apple...

    Am I the only one...? re: Ipod line-out

    To those who hear the SQ difference, it will be helpful to look into how Apple designed the line-out and headphone out in the 5G. Below is part of the DAC WM8983 signal path diagram referenced by the Rockbox developers. It has appeared to be identical to the speicifc CODEC used in 5G. You...

    Am I the only one...? re: Ipod line-out

    It is important to control the volume on the headphone out on the iPOD 5G when you do the SQ comparison with the line-out. Apple fixes the line-out at 0db and that corresponds to 90% volume level on the headphone out. Here is the setup: I played lossless WavePack files on Rockbox. Volume...

    Why is noone competing with Xin?

    Quote: Originally Posted by digitalcat How do you like the supermini-3 with K501? I like the sound of AD8397 but I wonder if there's another opamp that has more soundstage and a little bit warmer sound. The MINI-3 with gain and bass enabled drives K-501 very well. K-501 is my...

    Pictures of your portable rig- Part IV- A fresh start

    Quote: Originally Posted by jnev nice setup, but why are you amping through the headphone-out rather than the line-out? It's a good question. The 5G line-out in fact shares the same internal amp and signal path with the headphone out, and thus the SQ. It's not the true line-out...

    Rockbox for iPod Video Fully Finished??

    I have been playing lossless Wavepack music files on my 5G without a single problem for almost a week. EQ is off and no crossfeed. The playback is smooth and the sound is just fanastic. The EQ and crossfeed, however, still need some work. It is expected as Rockbox 5G is very muck a...

    Quote: Originally Posted by K2Grey While the DAC may indeed be handling the task of amplification, it's still not necessarily the case that Apple did not put caps or whatever in the signal path and so on. I really doubt it's a direct DAC - out connection. It'd probably be nice if someone...
