I'm getting a little bored with the T50RP driver and am looking for recommendations for other drivers to tinker with.  Something that is relatively easy to get at a reasonable price ($50-75 a pair), and that would be relatively forgiving of enclosure would be great.  

I have some CL3 rated speaker wire that I wanted to use to make an AC power cord.  The speaker wire is discontinued and I haven't been able to find the specifications on what voltage rating the polyethylene dielectric has.   Doing some research, CL3 rated wires are supposed to handle up to 300V...

How much does DC cable length matter?  I have some gear incoming that has a separate box for the power supply, and I wanted to keep them separated by a few feet (amp on the desk, power supply on a lower shelf) if possible.  I have some 18ga wire that I was going to twist up and shield to run...

I have been here a while and have a good pulse on what is available, but I wanted to make sure I wasn't overlooking anything new or obscure.  I have the HD650 and HD800 which represent two different sound signatures, so I need the DAC/amp combo to play well with both.  I am looking for as...

I don't expect that any IEM could replicate the open, detailed spaciousness of the HD800, but what comes closest?  I might have to move entirely away from headphones to IEM's exclusively and am trying to get an idea of what my choices are.  I listen to a lot of classical so ability to reproduce...

In preparation for my incoming CEntrance HifiM8, I decided to try my hand at making a Micro USB B OTG to USB B cable so that I can use my Galaxy Note II as my transport.     It turned out alright (confirmed to work with my Note II and my Nuforce HDP) so I decided to post this tutorial for...

In anticipation of an incoming CEntrance HifiM8, I decided to switch to a balanced cable for my portable of choice, the Sennheiser Momentum.   Only problem is that there is a TRS 2.5mm jack on only one side, so while making a new cable is a breeze, it wouldn't be balanced.  Since I didn't...

I was thinking about doing a steampunk makeover of one of my amps and was hoping to get recommendations for cool looking tube recommendations.  Metal bases, weird shapes, etc.  Hopefully I can find non-functioning ones for cheap.  If you have non-functioning tubes that would look cool for the...

I understand that there isn't likely anything off the shelf that I could install into a DAC, but if anyone has had any experience taking apart commercial USB to Spdif converters, I'd love to hear from you.  Looking for a simple install (like jumpering output to input). 

I had planned on using Par-Metal for a couple projects as they fit the bill from a value standpoint, but they are out of commission for a couple months recovering from their fire.  Looking for other sources.  Modushop.biz looks nice, but shipping kills a bit of the value.  I see some stuff from...

I know outboard USB to spdif converters are all the rage right now, but I am trying to find single box solution for a USB based DAC.  I also like 24/192 capabilities.  The more compact the better, but that isn't as important.  Up to $1000, but would prefer closer to $500.   So what DAC has...

Is anyone familiar enough with the ODAC to identify what I burnt up?       Must have hooked up the power supply to my speaker amp incorrectly.  Amp works fine still, but ODAC got sizzled.

Despite my best efforts to avoid further expenses for Headfi, I found too good a deal on some pre-populated B22 boards to pass up.  So now I am trying to source the rest of the components as cheaply as possible without sacrificing performance.     I will be going balanced for the B22 and...

I feel silly asking, but I hadn't had to think about them before.  Anyways, are there any standard standoffs that people use? Steel?  Aluminum?  I have only ever used circuit boards designed to slide into enclosures.  Thanks!

I am going to build a simple splitter/switchbox with an input from a DAC and an analog in being split between an output to my headphone amp and to my speaker amp.  I did this before in a plastic box and had to wire grounds for all my RCA inputs and outputs.   This time around I am using a...

I want to build some linear power supplies for my Nuforce HDP and my Sonic Impact Super T Amp.  In looking at various kits and plans, I am realizing that I don't know enough basics to even figure out if a particular power supply is the right one for my equipment.     I have tried doing some...

I found some really neat tins roughly the size of the traditional Altoids tin at an arts and crafts shop today.  Slightly taller, and maybe a tiny smaller footprint.  3.63" x 3.38" x 1.31"  Anyways, I was wondering what opinions were on the best amp that I could squeeze into one.  Obviously the...

I got a great deal on a used Metcal SP200 just in time for an amp build (Objective 2).  I have a standard conical 700F tip on it and was wondering if there was a better size or geometry for doing circuit board stuff.  Reading through some old threads I understand a flat (screwdriver) is good for...

Not 100% a DIY question, but I know there are some amazingly knowledgeable people here who might be able to explain.   Basically, I hooked up a new, regulated power supply (Goldsource 13.8V 5A from Amazon) to my Sonic Impact Super T-amp (TA2024 based) and I heard some rice krispies (snap...

Hi all, I still dream of an LCD-2, but I'm pretty sure it will remain out of reach unless I sold all my gear (which would leave me listening to it out of my laptop).  I have read a bit about a modded T50rp being able to get 80% the way to an LCD-2.  While it might be hyperbole based on the...

The Shure SRH840 was my first fullsize headphone purchased through my exposure to Headfi so they have a special place in my heart.  I have done some minor mods and made various cables over the past couple years, but I have finally finished my complete mod:   - Rewired (for the second time)...

Hello, been away for a couple years due to school.  Currently have an HD650 paired with a Nuforce HDP and am quite pleased with the combo.  In fact, every time I have thought about trying a different pair of headphones in the same price tier (AKG 70X, Beyer, etc.) I have shied away just prior to...

I really enjoy the sound signature of my HD650's and would like to get some nicer IEM's than my E2C's and MEelectronics M6's. The E2C's lacked bass and are almost 4 years old now, and while the M6's gave me the bass I was missing, the treble was a little too harsh and I just couldn't get a great...

I am a fan of Mogami W2893 which is a starquad of 26awg conductors, which has worked wonderfully for some short headphone cables and interconnects. At what length (extension cable) should I look at a lower awg of conductor, any? I probably wouldn't exceed 15 feet at this point.

The powerswitch (push button, latching) on my Bravo amp, no longer reliably catches (like 1 in 15 tries). I have resorted to simply unplugging the power cord, but do not like that idea. I bought a small toggle switch from Radioshack with the intention of removing the old one and adding the...
