I was looking on Amazon today and they list the HF5 for $99 ($50 off MSRP), which I am very interested in because of their analytical/neutral sound; I have been looking at getting them for a long time. THEN I saw the X10 on for $85! (and they're regular $300 MSRP or something crazy like that)...

No it's linear. I didn't think log vs. linear would affect the amp like that, I thought it would only change the rate at which the volume would change. And as I turn up the volume it's not like it gets loud really fast, it just jumps incredibly loud from one instant to the next. I tried to turn...

thanks for seeing my stupid grounding mistake. I fixed that and it sounds better, however, the music is very, very quiet when it's at low volume. When I turn it passed about a third volume it suddenly jumps very loud with a lot of noise. At this point if I slowly turn the sound down the noise...

Here are the photos I took of my circuit. Wasn't able to upload them in this thread so here are the links. If you have any questions about them or want me to take another close up of a certain part, just ask.   General circuit (the wire on the bottom left is an unterminated wire attached to...

Hey everyone. I recently built a simple CMoy amp and for the life of me I cannot figure out what is wrong. I have read other cmoy troubleshooting threads and I haven't read of any problems close to mine. I do get music in both channels, but very shetcky things are happening. My problems are...

Ok, I'm pretty much set on the HD600 now.   As for the amp, the O2 looks great from what I've read, and I've always loved things that have supreme functionality and don't care about looks. The fact that it can be compared, perhaps be better than $1000+ amps is amazing. I do still want the...

I just read the article that jackwess linked to. It sounds like the HD600 is definitely the better choice for many things, but I am not too keen on getting the $600 amp they recommend to drive it. If an amp like the E9 will drive it suitably (on a lower volume) than I would lean much more toward...

well I want open headphones but I probably won't be taking them out. I will however be taking my HD448 out more often once I get the open pair, and I do not want to get two amps. I really want an amp even for everyday portable use because I have a tiny E5 now and even with that I can really...

I forgot to mention I was looking at the HD598 for a bit too. How does this headphone compare to the HD600? If there is much of a difference than it's probably worth it going for the 600, roughly $40 more.

Hey head-fiers,   I really want to upgrade to better full-size headphones. Currently I only have my HD448 which I love, but I know there are better headphones out there which can blow me away with their sound quality. For a while I was toying between the HD600 and HE-300 which both look to...

Is it true you can attach the ground to the 11/15 pin bridge? I have heard this before but in all the tutorials people have typed or pictures they have uploaded they have used pin 2 for the ground. If the ground does operate from pin 11/15 it'd be much easier to solder.

I'm planning on making a DIY lod for my ipod classic (160GB, newest version, using it with FiiO E5 amp).   I read in an earlier post that the resistor is only used to "fool" the iphone into accepting the hardware. In that case, do I even need a resistor in the cable if it's only for an...
