I don't have a stock LCD2/3 cable handy, and I wanted to check if the XLR connectors at the headphones are 3 pin or 4 pin? And what is the layout?   Thanks, Mike

For those using a separate transport and DAC with their computer, and therefore the need to route a S/PDIF cable between them, I would like to know what kind you are using and what you feel is best?   The types I'm thinking of are   optical coaxial (RCA connectors) coaxial (XLR)...

Anyone know if the Hifiman headphone connectors are standard, perhaps a type "N" BNC or something like that?

This isn't quite a DIY question-- but you guys know a lot about physical properties of materials, so I thought I'd ask here.   Is it safe to clean a CD-R with alcohol? I'm experimenting with cleaning them before burning them. I think I remember being told there is a "mold-release" compound...

is there a simple way to tell by serial number whether my LCD-2 is revision 1 or 2?   it's 5313896

I used to own a K1000 and I remember that it had superb "outside the head" imaging. I sold it a while back. I just picked up a Hifiman HE-500 and I'm impressed with the imaging, and it does get "outside the head" and feel "open" almost to the degree the K1000 did, but it's been a while since I...

How about a comparison of the HD650 and the HE-500? These two cans are close in price, especially once you consider fancy recables.I will soon have both at my home and will try to rapidly burn-in and listen. I will also have upgrade cables (Cardas) for both.   Currently I use the LCD2. I'm a...

I need to replace the potentiometer (volume control) in my Hifiman EF5 and I'm going to upgrade it and move it into a separate box as there is no room in the main box for anything larger than miniscule.   One issue is that I prefer the sound in the high gain setting but I use a fairly...

Has anyone here delved into the interior of a Hifiman EF5? I am planning to replace the pot and I want to know what pot value to order so I can do that ahead of shipping the EF5 to my tech guy.   Mike   EDIT: I'd like to add a question about choosing the pot, in particular a stepped...

I would like to hear the HD800 with my system. I need a single-ended cable to use with my Hifiman or Woo. If anyone in the LA area with an HD800 is interested in getting together, let me know.

I'm thinking of getting the tubes I'm using with my Woo WA6-SE cryoed (currently using a NOS RCA 6DR7).   I'm interested to hear stories of changes from cryoing tubes, for the Woo or other amps.

Here is an admittedly crude poll, a start. But it might get some thinking going, and might lead to more interesting future polls.   MULTIPLE ANSWERS ARE PERMITTED, it's easy to imagine someone fitting in multiple categories... so you can say something like "I'm acostic with the Audeze and...

Here is Los Angeles, at KUSC, Jim Svejda is a genius. He is a wizard with language, both composing it and speaking it. He is an encyclopedia of classical music knowledge and illuminates every piece with some fascinating detail, or ties several pieces together. His speaking voice is the best...

I'm not too into jazz improv (I'm a classical-adapted listener who likes phrases to be perfectly balanced and shaped as only pre-planned composition can do) but I like good percussion playing, and jazz kit sounds really good on my headphone system. I'm wondering if I can get suggestions for jazz...

This survey question is somewhat related to science because it's about how we use attention, probably in aspects that could be tested.   Depending on the recording and playback systems, music can have a close-up perspective or far-away perspective. Is there one you prefer (answer survey) and...

I have a way of looking at things ..  my sixth sense guides me to building and modifying a system that is as accurate as I can get it. There are engineers who disagree, and that's fine. For the most part I think their work does a poor job of reproducing a musical performance, but I'm sure from...
