Hey, I'm trying to get started on building a KGSS electrostatic amp. I've been searching around for any KGSS PCBs, but I'm having trouble procuring them. If anyone has any suggestions as to where I may get some, or if anyone here happens to have any that they'd be willing to part with, for a...

Hi, I'm looking for suggestions on a (rtelatively) basic and simple DIY amp for electrostatic phones, maybe with pre-made PCBs available, if there is anything like that? Maybe I'm asking for something that doesn't exist, but I'd appreciate any suggestions?

Let's take, for instance, an opamp that is running with 15mhz bandwidth, and a current buffer that's rated at 40mhz inside the feedback loop. I've heard somewhere that the general rule of thumb is that the buffer should be at least ten times the speed of the opamp; anything less, and the...

After using the AD823 for the longest time, I just recently tested a BB OPA2227, and I was surprised at how artificially bright and glaring the AD823 was in comparison. The Burr-Browns made the AD823 sound harsh. I was wondering if I should have the same reservations if I were to decide between...

After I connected a TI railsplitter, the voltage reading on the positive side of the power supple is 2.6v while the reading on the negative is 3.5v, while the battery's total voltage is around 7.6v. Did I put the solder iron on the railsplitter too long and fried it? Would the voltage reading be...

Regarding the TLE2426... 1) I heard that this thing gets imbalanced when your load draws more than 20 mA. Would this imbalance be worse/better/same than the same conditions with a regular resistor dividing scheme? 2) Suppose I'm using two BUF634's and one AD823. The AD823 draws 5.2 mA at...

I currently have unstacked BUF634's running in normal bandwidth mode in a single 9V amp. Here are some questions: 1) I know the procedure for stacking the Elantecs is to place their pins in a corresponding manner and solder them together. Is it the same for the BUF634? What about the 5-pin...

I have the toughest time wiring my pot, a 10K Panasonic. The connections are never very secure, and soldering is always precarious as solder can easily flux from one pin to the next. I've fiddled around with the pot so much, soldering, desoldering and resoldering, that the thinner parts of the...

I thought some of you might like this info. I emailed this one guy a couple of weeks ago, Michael Santucci, who's a sound professional at Sensaphonics, about the effects of high and low frequencies on one's ears and hearing damage associated with them. I stumbled onto a website on healthy...

Nevermind, it works now! -------------------------------- I'm having a little bit of trouble with my amp, particularly my volume pot. Sound usually comes out fine on the left channel, but there's nothing coming out of the right. When I turn the knob really quickly and it makes a clicking...

I'm using a Panasonic 10K volume pot and I find that the shaft is so long that my volume knob doesn't fit on it very well. It tightens just fine, but the length of the shaft is problematic in that it makes the knob look like a mushroom. This is especially apparent when you look at the amp from...

Say, for instance, that I have a Creek OBH-11 and Grado SR-125 setup. Which upgrade would get me the biggest jump in quality: from the Creek to an MG Head OTL, or from the SR-125 to SR-325? Although I love classical, I also want to keep the dynamism and impact that's good for rock, which I'm...

If I play an HDCD-encoded album with an HDCD-decoder-equipped CD/DVD player and run it through the digital out to an old non-HDCD external DAC, would I still reap the benefits of HDCD, or would I need an HDCD-capable D/A?

I thought this Aiwa XP-Z5C portable MP3-CD player looked interesting. Click the link, take a close look at the specs below and you'll see that it uses a 16-bit D/A converter. I figured it was at least noteworthy seeing as how 16-bit DAC's are a rarity these days in regular portable CD players...

Has anyone here ever tried the Philips AZ922517 portable CD player? I'm interested in buying this particular player because it's cheap (I can get it at way less than what you would think) and it has a digital optical line output so that I may connect it to an external DAC. However, I'm curious...

I'm going to buy this, a right-angle, mini-to-mini adapter, to complement the new pair of headphones that I'm planning on getting (most likely a pair of Grados) mainly for use with a portable player. I mentioned this to an audiophile/engineer friend of mine, and he remarked that a right...

Are there any pure-metal adapters that convert mini 1/8" (or standard 1/4") plugs to 1/8" plugs that are L-shaped, like most portable headphones have? I want to use certain headphones with my portable players, but the straight-shaped plugs are restrictive and non-conducive to portable use.

I'm planning on getting a portable headphone amp eventually, but for the time being, I'll have to ask this question: Which headphone, the Grado SR-225, SR-125, Sennheiser HD-590, sounds their best when driven straight out of a portable's headphone jack? I hear that Grados sound great straight...

Would someone please describe to me the differences between using the headphone outputs from a receiver or integrated amp as opposed to using a dedicated headphone amp? I want to know the sonic differences that I should look for so that I can justify spending 200 dollars on another component in...

Hi, I'm a newbie and I'm thinking of buying a dedicated headphone amp, but I'm a bit hesitant to do so because I have a few questions that I need addressed. Forgive me if I sound stupid in the process. From what I've been reading on this forum, I've come to the conclusion that the headphone...

If I could purchase the AKG K-66s for $36 bucks, should I do it?

Can anyone recommend a good CD player case? I just bought a TDK Mojo and I'm looking a something thin and small (about the size of the player) to tuck it into while I'm carrying it around so that it won't get hairline scratches on the LCD. Nylon reinforcement at the edges would be nice, but I'm...
