My friend asked me for advice on speakers to buy for primarily watching movies, 5.1 channel, so as I don't know anything about home theatre-related audio, I thought I would post here on his behalf and get suggestions. His price range is up to $300. I know that's low but he's not an audiophile...

Is there any sound card with lower than -100 dB noise/distortion of its input (preferably lower than -110 dB)? I want to avoid renting an Audio Precision to do distortion measurements since it's over two thousand bucks a month where I live. And I mean not just for 1 kHz, but at least 10 kHz...

Diptrace vs Eagle vs Kicad vs PCB (gEDA) vs whatever I missed. Kicad is free but I get frustrated with it. I couldn't figure out, for example, how to drag multiple pads at once: selecting pads only allows move, not drag What?! I asked on their fairly active Yahoo group and got no reply...

At my job we've developed a multi-display kiosk-type thing that needs a lot of power for the displays and high performance computers inside. Since typical mall outlets in Canada are only 15 amp, and in the US only 20 amp (plus one has to leave some margin, can't run too close to the breaker...

Anyone know of a clock buffer/distribution chip with very low additive phase noise? < -115 dB at 10 Hz offset. I thought of using AD9510 but it's very complex, needing programming internal registers, and has a bunch of crap on it I don't need so it's a waste of money too. Clock I'm feeding it...

I contacted TI with a question about some parameter of a device they're selling. Instead of getting a response to that, a few days later I got a request to fill out a survey evaluating their (nonexistent) response! What?! Well I did fill out the survey and made it pretty clear what I thought...

I'm looking for hermetically sealed small signal latching relays that use a spring rather than permanent magnet latching system, with high quality contacts.

I need to rent an audio frequency spectrum analyzer that resolve to -110 dB. I'm having trouble finding rentals for such things in Canada. Buying one is out of the question, as I don't have $10K+ to spare (maybe after I pay my $60K student loans and $15K credit cards).

My hard drive waterblock sat atop of the drive's circuit board and motor side, and the space was filled with a thermal transfer compound that cured to a consistency a bit softer than silicone, so it could be easily removed. I recently switched to another drive but I don't know where to get this...

AES 60th Anniversary

How much copper would one expect on average in the motors and wiring of an electric car (in kg)?

I thought this looked pretty interesting: Circlotron Amplifiers Once Again Only downside I see is that the voltage gain seems to be provided by the P-MOSFET.

I'm not getting notification emails of replies and PMs, despite having the option of "Instant Notification" on in Options, as well as a correct email address in Email Settings. So, what gives? I'm surprised that the forum software of a site of this size would be still buggy after all these years

After several years finally what looks like a definite raise in the performance bar: Stereophile: ESS Sabre Reference Audio DAC The 134 dB SNR and -118 dB THD are nice, but there's more interesting things in the white paper: http://www.esstech.com/techsupp/sabrewp.pdf Too bad it looks like...

I want to find out if people are interested in a group order for clocks? I found something and they gave me a quote, but it's for a 100, and that's way too many for me at this time. So how would I post appropriately to find out if there would be enough people interested in a group order?

I'm hoping someone would be knowledgeable enough to help me here. Motherboard is Asus P5LD2 Deluxe and I have two sticks of OCZ2P10001GEE which I had been running dual channel at 3-4-3-11 and around 950 FSB. I was having some random crashes over the past couple of days. Looked inside and...

I got custom molds with ER-15 filters. Now for every step I take, when my foot hits the ground, I hear *boom* like it's conducted through the bones. Same thing if I hit my wrists together, and my voice is a bit booming too, and moving my jaw is loud as well. The voice was booming with the...

I need custom ear molds to use in both clubbing and to plug in my Etys. Etymotic's site references two local labs and I would like help in choosing which one to use. http://www.otohearing.com/ and http://www.protectear.com/ The former has two different materials, one silicone based, the other...

Let's see what the recent studies say: "Tumour risk associated with use of cellular telephones or cordless desktop telephones" 2006 http://www.ncbi.nlm.nih.gov/entrez/q..._uids=17034627 From the abstract: "We found for all studied phone types an increased risk for brain tumours, mainly...

I broke my ankle last month--spiral fracture of the distal fibula. After six weeks, during four of which I wore an Aircast, there's pain throughout my ankle and foot area every time I step, and both still get swollen during the day when I'm upright. Today's X-ray showed that the fracture appears...

I'm just reading this in the news today: http://www.canada.com/topics/news/na...34a064&k=95624 Ontario to ban incandescent bulbs, in favor of energy-efficient CFL ones. Australia and at least one state (I think it was California or Washington) have similar legislation in the works or passed...

Now that Google has bought DoubleClick, let's review a few scary facts. Consider the following quote: Quote: Google ad sense operates on a different level...using cookies is just part of the game. Via IP pingbacks, toolbar tracking, and account identification, users may unkowningly be...

I'm wondering how a cathode follower buffer such as the one from tubecadjournal below compares to the two JFET Borbely buffer in terms of distortion (not merely THD, but sound as different types of distortion have different audibility thresholds)
