Built my own battery generator for hi-fi duty. It powers my DAC and amp. 12V LiFePo4 by 100Ah; lasts most of the day and my entire rig draws over 60W which is a bit high for headphones. (12.8 Volts DC nominal voltage) x (100 Amp hours) = 1,280 Watt hours ((90% efficiency) x (1,280Wh)) / 65W =...

Hello all. So a friend here on Head-Fi told me to sell my desktop DAC and buy Soekris because I was using SPDIF which is apparently FLAWED... Well I bought a Soekris DAC1101 and while it sounded very very decent for the price I felt it did not best my desktop. Fast forward to an out of town...

Hi. I recently bought a Nakamichi TA-2A speaker amp to power my Arya headphones. I understand Nelson Pass had something to do with the design of these specific amps and was interested to hear what it could do with a capable planar. The price was about right and reviews are typically rather...

Hey, hoping some one knowledgeable about this sort of stuff sees this. I'm trying to fix my dad's old TT. I've got sound for a few seconds before it starts skipping. I can see the needle flexing and then jumping back, so the tonearm seems to be having some tracking issues. It's not the...

Compared with my ghetto H320 this thing just doesn't compare. Musicality is up there (like a built in rock eq setting or something...) with the added bass, albeit a bit bloated, being enjoyed by my iM716's, but the resolution just isn't there like it is with my iRiver. Even outputting to my PPAS...

Has anyone actually opened the driver housing on their iM716's? I did for both my iM716 and iM616 and they have a single tiny surface mount resistor for each channel. I'm not really sure what they are even for. I bought some 75 ohm resistors for the podectomy, going a little high in value...

I was thinking about how people care so much about what their headphones look like, yet they can't even see them when they wear them. Then today I noticed for the first time that I actually can see my CD3K's while on my head! Can anyone else see any part of their headphones (cables excluded)...

I used to have my entire rig plugged up straight into the outlet in my bedroom. We recently got a rack for all our audio gear, and I've been able to move everything out by the computer. I plugged everything up into a power brick in the living room and, for whatever reason, the difference is...

I went from Headfive, to PPA and am now currently waiting on a PPAS. The PPAS will be a fun little project that I will be able to listen to and compare with standard sized PPA's, but I don't plan on keeping it as a long term, main rig home amplifier. (I downgraded to help afford an upgrade if...

As you can see form my profile and sig, I have a thing for a band called Electric Light Orchestra. I've turned a few people onto them that go to my school, and I really feel they have something in their music for everyone! I recently purchased the last album from ELO Part II to complete my...

I'm looking to create my own set of custom molded IEM's. I'm trying to get the best SQ out of them as possible, obviously, and need to know a place to get a few of these drivers for relatively cheap. I've checked DigiKey as well as a couple other supposed suppliers of Knowles Acoustics ( Link...

Note to mods: Wasn't sure whether it belonged here or in the DIY forum. You guys can obviously move this if it is inappropriate. Thanks for your understanding. Preliminaries: Well there was a thread a little while ago about this guy.... Here-----> Linky There were mixed...

Well I've been looking around for some ear pad replacements for my Sony CD3K's. Of 'course I could go the BORING route and just buy a pair from AudioCube for like $40, or I could have my mom do something fun and exciting for me. At first I was looking at SA5000 pads. I thought they looked...

The ear pads on my CD3K's are not really that bad, but I foresee replacement in sometime within the future. I'm sure supplies will dwindle down and surely out of existence some day, it's just a matter of when and how soon. I've been looking at the SA5000 pads and wondering. They look like they...

I tilt my head to the right and I'm hearing more bass on the right. I tilt it to the left; more bass on the left. What's up? I'm making sure to keep relatively equal pressure on either ear from either pad... I just can't explain it. Any one else willing to give it try, or has some one else...

I have a Daewoo DVDP4851 and was wondering if there are any basic and generic mods to do to it? I opened it up and there's a lot of stuff that I haven't a clue on what it does. I'm thinking about the replacement of some caps and possibly opamps, but Idk how difficult a task like this would be...

Forgive me for my virtually instantaneous first impressions of the CD3K's. I've only been able to listen to them for, at most, 2.5 hours, however those were some of the best 2.5 hours of audio induced euphoria of my life. The K701's sound good, darn good. Going from the MDR-V700Dj to them was...

Recently (a little less than a month ago) I bought a Headfive to go with my K701's. Recently (yesterday) I purchased a pair of headphiled CD3000's. (In case you were wondering, yes, I do hate you all... ) I'm wondering if my Headfive will do the CD3K's justice. Even if they will match fairly...

Title says it all. I'm looking for the best Redbook playback possible in the $50-$150 price range. Will be mated with an external DAC of some sort. (Looking at the DAC-AH, Zhaolu, Entech Number Cruncher, etc.) Amp = Corda H5 Headphones = K701 What would give me the most...

Idk if this is better suited for another section of the forum, but seeing as this is the "General Discussion" area, I'm guessing it's OK? I REALLY want to hear a pair of CD3K's to A/B with my 701's. If any one in the Chicago land area has a pair, I'd be extremely interested in meeting up some...

Well I got into classic rock a little while back. Yes, Rush, Genesis, George Harrison, Eric Clapton, Jethro Tull, Chicago, The (Guess) Who, etc. I liked it all pretty much, but something was missing. Then I stumbled upon Electric Light Orchestra. Everything just fit. I loved downloading all...

Well I have about a year to save up for something, so I thought I'd get some good ideas on a setup, and then when I have the money and see how much has changed. For college I'm looking to get the ultimate setup (for me at least). Right now, I have a pair of K701's and a Headfive in transit...

I'm looking for a nice (cheap) amp to run my future headphones off of. Right now I'm heavily leaning towards the DT990's meaning I need something fairly beefy to supply that kind of voltage. Tube rolling isn't a must, and neither are tubes at all. I'm simply looking for a good, well...

Well I'm still looking for some good ELO headphones. I'm not interested in rock and roll oriented cans, so please no Grado suggestions. (Sound isolation is also a HUGE plus, but can be sacrificed) I'm currently looking into the Go-Vibe V5 or Supermini IV as my main/only amp. (portable and home...

I'm sry but this didn't exactly fit in any specific spot. The Portable Audio section is for source talk only it seems and I'm already set in that regard... What I'm basically looking for is some setup ideas. I know that most of this is personal preference, and I have a few ideas I'm sort of...
