12 year old thread resurrection? This is a record for me. If you want to try very large film capacitors why not go for Solen? They are polypropylene and are made for this purpose (audio). No point gong for polyester if you're set on using a physically huge capacitor already.

Yes, that is the post I was referring to. I wasn't able to find anything else on the internet.   THD is much harder to measure, never mind at the performance level that a sound card or a DAC is capable of. But there is a possibility that your mismatch was caused by something else. RMAA will...

Digging an old thread but that's exactly what I just found for myself and googling led me to this thread. I mean, RMAA seems to subtract 6dB from channel crosstalk results (making it look much better than it is). I confirmed this on 2 different devices (one amp and the other dac+amp) and using...

I have installed the bootloader from the exact same page last week and I just installed the 3.3 version. It still behaves like before. I suspect my CF adapter does not work well with my CF card or the CF card itself is not compatible. I'll try to buy another adapter, at least they are cheap.  ...

Thanks for the suggestions. I already flashed a new bootloader (7.4 pre 1 - doesn't seem to be anything newer and this one is a hack as it is) - and the nightly build of rockbox. I am not sure what do you mean by flashing the ram/rom? Is there an option in the menu to do so? Btw you can't really...

I just installed 64GB Kingston 266X CF card in my iPH-120 and I'm having a strange problem. Any song plays for 10-60 seconds and then skips to the next song. Every time.  I can't find any reports of similar problems, and I tried latest bootloader and rockbox, no change. Reformatted FAT32, copied...

How much difference you'll hear depends on how good is your single ended amp. Many don't have ideal channel separation. I am also planning to reterminate my T1 after I finish my balanced beta22.

Tesla T1 is really good. I am a bit unhappy with quality control - had to send mine for repair due to buzzing - but they look and sound like they are worth their high price. Super comfortable too. Their sheer speed is better than anything I listened to. Piano and guitar sound amazing because of...

You pretty much need to design a circuit board for that, though. You also have to order the chip from the supplier. While you could just hack the analog circuit as well as buy parts in your local electronics store. And it is probably cheaper, too. I agree though, if I was designing something I'd...

I was asked to repost the image since the original has disappeared. I don't seem to be able to attach anything to either old or new post even though it's only 5k so here's a link.   http://www.aoselectronics.com/gfx/web/lobatt2.png

I think I got them from EBay last year.

Headroom diagram is spot-on. It's obvious you need two wires per channel. It's not possible to have "balanced" headphones with only three wires, not you can connect together any of those 4 wires (and neither you can involve ground with any of them). To do so will at least make the amp not work...

I use Audio Technica ATH-900 - I also work as a programmer and want to drown out the talking, though it's not as bad as your environment. I found they work very well in this regard without compromising sound quality too much. Extremely comfortable. I also have HD-25 II and find those great for...

It really is insanely difficult to remove the plastic cup. I actually damaged my pair trying to take them off (broke the little plastic bridge on top, no biggie but annoying). Even opening an Acer Aspire One is way easier than this.

Quote: AOS: I hear what you're saying but I've never been instructed to use data sets when matching transistors. the single scalar number seems to be what you use, since the test conditions are the same (temperature and voltage under test). That's because if you match two transistors...
