    To clip or not to clip...?

    OK, so apparently I have been confusing clipping with 'tape saturation'? Didn't know there was even such a thing.    I am happy to know that my gear then probably is ok, since I am not alone hearing this.   Indeed, the MoFi version is much less pronounced, but still very audible in my...

    To clip or not to clip...?

     SHVL 804, I believe that's an EMI-Harvest release.   However, I also tested the same clip of the 'Shine on' boxset edition. Same story. Clip here.   Also listen to this clip from a rip claimed to be from the Mobile fidelity version: here. Clipping is much less pronounced in this version...

    To clip or not to clip...?

    Have been contemplating what could happen to me if I would post this... Being called a lunatic? heretic? burned alive?...   Anyway, here we go: do I hear clipping in these samples from   1) Bjork - Homogenic Live - Hunter and .... 2) Pink Floyd - Dark Side of the Moon - Time .....?  ...

    Presenting LJ-A: SD-card transport, S/PDIF and USB DAC integrated

    Hello,   I have seen this thread has seen 100+ reads, so I thought I'd give an update of my proceedings.   After having also posted on a Dutch electronics forum I got plenty of feedback of things to improve, things I forgot and other constructive critique.   This has led me to the...

    Thoughts on "Metallic Spheres" by The Orb featuring David Gilmour?

    Quote: Ah, that probably explains why I was not really shocked.   I have, in the mean time, checked 3d60's webpage and listened to the demo. It does add a new kind of sensation; will see if I can have a listen to the complete 3D60 version soon.

    Thoughts on "Metallic Spheres" by The Orb featuring David Gilmour?

    Not really to my taste, though I like Mr. GIlmour's other work very much.   Reason I wanted to listen is that this album made the major headlines over here in the Netherlands: "3D gaining momentum, also in audio". For the non-Dutch speakers: this article introduces this as the 'first 3D(60)...

    Presenting LJ-A: SD-card transport, S/PDIF and USB DAC integrated

    Hi all,   Having gotten very interested in hi-q audio recently, I have set out to build my own digital transport. The main reason is that I could not find a transport which plays losless from SD card (WAV and eventually FLAC) does not require a PC/Mac/Linux whatever to work adds quality...

    PPA v2 construction discussion

    Quote: OK, figured it out: I had already ordered 6 new rail isolation jfets (the Q3s), because was seeing strange voltages on the opamp power supply pins.   While reading the tweaks section of Tangent's website I found this sentence: "You may have noticed that you can jumper across...

    PPA v2 construction discussion

    OK, some additonal troubleshooting info: Removed the TLE for the (dead) right channel from the circuit to verify it's working: nicely splits 14V in half. So I guess that rules out the TLE as the source of the problem. Also removed the opamp for the right channel from the socket to rule this...

    PPA v2 construction discussion

    Quote: Removed the jack (and switch) completely and took the board out of the case to make sure there's no ground loops there. Power supply is OK, nice flat 13.4 as indicated before. I did some additional measurements:   (these are the output resistor pairs, 2.2Ohms, there used to...

    PPA v2 construction discussion

    Hi, back again but now with some not-so-good news.   It seems I have fried my PPA while trying to power it off of an SLA (battery). Turned out the wires in the DC connector to the PPA were shorted inside. I did not yet have a fuse in the battery wiring to the PPA, nor any kind of current...

    DDAC Clone - 12-way parallel TDA1543

    Quote: Thanks, very good suggestion. I am working on a new version of this DAC and for sure will seriously consider including this IC. For sure will have an SD-card reader + player + USB interface included (also optical, coax via WM8805)   If, BTW, you have any suggestions for...

    DDAC Clone - 12-way parallel TDA1543

    Hi, just sent you an e-mail that the board is on it's way. Just to be sure, also posting them here!   Very curious about your results, please share them here!

    DDAC Clone - 12-way parallel TDA1543

      Quote: Thank you for the compliments! Maybe this will indeed inspire others to pick up work in this area as others have inspired me!   Schematics are below, I can not find a way to attach the board layout/gerber files to this message...? I am planning to do a second version...

    PPA v2 construction discussion

    Quote: Hi, I'm back!   Built my DAC, see this post for details.   I am convinced that with my DAC, the 'issue' of not noticing bass boost effect is not at the source (still can't hear a difference when flipping bass boost switch). Will have to open up my PPA to put in the 3PST...
