I'm thinking for 'upgrading' the caps in my DAC but still not sure which to use. My choices now are the Black Gate NX HiQ 47uf and Black Gate FK 47uf. The replaced caps are Sanyo OSCON around the DAC chip in the pic:     The NX HiQ is really, really to find now while the FK is still...

I've just received the JTA kit from TPA. According to their website, input impedance varies between 2.2K and 10K. My source has the tube output stage which has ~1K output impedance.   My question is what input impedance I should use for this setup?   To my understanding, the amp's input...

I'm gathering parts to build a DAC based on the AD1865. Digikey keeps being out of stock so I decided to pull the trigger on one from ebay. Got one from here...

I'm wondering if anyone knows some really large cookie tin, or just a tin box? Something in the range of 16x12x3 would be awesome. I found a couple but most of them are vintage stuffs which I'm not really interested. A blank one like this is perfect for me:   Any suggestion would be...

Just out. Specs look interesting. Not sure about retail price. They also have a more affordable Audiophilleo2. Also, there's a comparison table which includes most of converters on the market. They yes, they mentioned Head-fi My guess is that the designer is also a member here...

I'm wondering what's the normal time to deliver a package after it already cleared custom? My package got out of custom on 16th but until now I still haven't received it. It's a quite expensive one so I'm very worried about it. Normally, it shouldn't take more than a week to ship within CONUS...

I'm finding a small and light flight case to carry my K1000 for traveling. Nothing fancy, just as durable as possible. I found some camera cases but they're quite big for my taste. Any suggestion is appreciated.

I'm looking for relaxing CDs, just instruments, no vocal. I really love the iRelax CDs. Anyone has some suggestions that sound like the iRelax? I've checked out the Bandari stuffs but somehow they don't sound as good as the iRelax.

Just wonder if any maths expert here could help me with this small problem. Compare the area of the black and white. Just note that the black is the shape of leaf, not circle.

Anyone knows a small dock that has charging, sync and true lineout? Something like the Apple dock is great. The problem is it doesn't have the true lineout. I also look at the SendStation Pocket dock but still prefer a dock that I put my iTouch stand. This one looks promising but again, I'm...

Hi guys, I'm looking for an entry DSLR camera for my forthcoming photography class. Since it's my first DSLR, I don't want to spend a lot on it. My options are the Canon XSi and Nikon D3000. I mostly take landscape and portrait pictures. Can anyone give me some ideas about which I should buy...

Anyone knows where I can get some MRE food? My dad loves them and I'm thinking of getting 2 or 3 boxes for him. The problem is that I once bought the wrong one (civilian, not military). I see some auctions on eBay but shipping cost is tremendous (~25$/box). Would be great if there's a local...

So after owning the iQube v2 for almost 3 months, I think I need to share some thoughts about it. I'm not a good writer so don't put flame on me for not using flowery words. Firstly, I must say I don't have much experience with portable stuffs. The only IEMs I owned were the ER4ps, W3s...

Just wonder if anyone here uses any charger on the plane? I'm thinking of getting one for my HP laptop to use during the flight. Still not sure if the charger will work with all airplanes The one I'm looking at is ~120$ which is crazily expensive for a mere charger. Is there any cheaper...

I'm looking for a mini projector for my dad. He only uses it for personal stuffs so it doesn't have to show huge slide, just enough for 10 people seeing is fine. What I want is the USB input for ease of use. Most of the mini projectors I found only have VGA input. My dad is not a technology...

I'm going to rebuild my little rig around the MBP. Most of my music library are FLAC and APE. My question is whether iTunes can FLAC and APE? AFAIK, there's a plugin for iTunes to play FLAC, but how about APE? If it's not possible, is there any software that can convert FLAC and APE to Apple...

Just a small question, is there any difference in the optical output between the Macbooks (white+unibody MB and MBP)?

I'm trying a way to get the best optical signal out of my laptop to feed my external DAC which doesn't have USB input. My laptop (HP dv9925nr) has the SPDIF out (3.5mm) but I'm not sure if it's good enough and offers bit-perfect. So, which way is the best for me to get 24/96 or 24/192 out of...

I'm thinking to upgrade my setup again (don't know when it'll end ). My current balanced rig is CA DacMagic -> LittleDot MK VI -> balanced HD650. I do love the MK VI and HD650 so there's no way I'll replace one of them. My preference music is smooth, bassy, kinda slow pace. I do hate the...

I'm going to build my first cables for my speakers. Just grasped some Cardas spades lug but still confused about this. Looking at it, I only see one solder pad, so I just wonder does it have the signal or ground? Or I only have solder to one place?

I've been thinking seriously about the Edition 9. It's one of the cans I'd like to try (beside the L3000). I especially have great attention the phones that have great bass. I've already have the balanced HD650 with several kinds of cables (Mogami, Kimber TCSS, Vampire and Jena) and the...

I'm looking some some bare, uninsulated, solid core wires. It should be really small, about 28,30 or 32awg. Copper or silver plated doesn't matter as long as it's conductive and I can buy in big quantity (>50ft) and cheap. I've done some search but only get some teflon insulated which I don't...

I'm thinking about adding an USB-to-coaxial/SDPIF converter to my desktop rig. I gonna have the DacMagic and intend to connect it with my laptop directly by USB. However, I also pay attention to the M-Audio Transit. Now, the question is,which is better? Can I have the sampling rate of...

I wonder if there's any kind of glue like that? It's because when I made some interconnects, before using the glue gun, I used the multimeter carefully to make sure there's no bridging. However, after I used the glue gun to seal the solder joints, the multimeter told me that there were some...

I'm looking for a pair of nice, durable power cables to replace the stock ones in my amp and DAC. I don't need any fancy schmancy here, so please don't recommend me any that I've to pay through the nose. My budget is about 100$ for a pair of them.
