Is there any correlation between sound quality and stylus width? The vinyl width on 33/45's is 40um, if that makes any difference. Do you think that a thinner profile stylus cartridge would be better at reproducing sound? Why or why not? ~Thomas

Hey guys, I'm looking for some equipment that'll prove useful when designing circuitry. When I say circuitry, I mean I/V converters, digital audio circuits, and whatnot (mostly audio). It's semi-serious, so I wouldn't mind investing in something that'll prove truly useful and worthwhile (not...

Okay, so I'm sitting and wondering... "Man, I really want to go balanced...but I love grados! And Lord knows no one wants to recable RS-1s (Larry of Headphile in particular, hehe). Very understandable, seeing as it's a rather delicate procedure and it could very well result in a busted RS-1."...

I'm wondering if there is any benefit to balancing grados / alessandros. I understand that the balancing doubles the slew rate and power going to the headphones (and RFI blocking), but would it effect the above headphones? Would it be worth the high cost of going balanced, or would single-ended...

Does anyone have any idea where to find the said cd module? I cannot find it anywhere but www.audiodiylab.com and it's back ordered and I talked with Solomon and it won't likely be their for quite awhile. Again, the internet is like devoid of that one piece of hardware (and I can't use the...

Hey guys, I'm going to get some boards made of these two beasts (dynatube "bamaslama", as shown in previous threads) This isn't for profit, but just to keep costs down. All those wanting a board can join (group buy maybe?) if not, you can always PM me and the first two people to PM me about...

Haven't heard of them? Well, perhaps you should give them a try...because... Good god! Amazing music! The sound, the emotion, it's sooooo good! I suggest everyone give them a listen, because wow, it's good stuff. (plus it sounds good quality-wise). Anyone else like them? These guys definitely...

Greetings, hehe. I'm looking to make an amp that surpasses my wildest expectations, but this time, I want to look into tubes. (Although the Beta22 will replace my M^3 probably next year.) The simplicity in design is remarkable, but I'm not sure which route to go. There is the DynaTube, but...

! Holy crap, I just happened on the website after looking for some information about the M^3 and lo and behold, he's got a new project in the works! The Beta22 amplifier. I'll let you read the details, but man, it looks amazing! Hopefully, it'll be out by Christmas or some time when I...

Hello everyone, You see, I need a pair of headphones that doesn't leak like my current MS2i's do (and they need to provide some sort of insulation from outside noise). I like a lot of indie pop music / j-pop / twee pop stuff, but I also like some metal (opeth and rammstein). I probably can't...

Hey again! Yes, I'm back with a schematic again, but I've learned a lot since then (redoing the board as well.) I just want to make sure everything checks out before I do the board again (hopefully no more revisions...). And here she is (meant to be used with the L1210 CD module and it's...

Hey guys, I need advice from people I guess; so I figured why not the Head-Fi forums? On a more serious tone, I figured that even with financial aid and the like, I cannot afford to go to college without accumulating massive amounts of debt. My goal was to be a mathematician / physicist...

Anyone know of a good supplier of these chips? There's a nice TDA1541A DAC being developed over at DIYaudio.com and I want to try it out. Any reasonable / reliable places selling these things though? I can't seem to find them anywhere... ~Tom

I've finished on of the many DAC I2S boards I'm going to make. It's for the PCM1794. No output stage was put in, because I want to be able to swap them out for testing. Attached is the schematic and the board. Any input would be greatly appreciated! ~Tom

I have the LL1674 transformers by Lundahl. I put them in my CD player with a MN6474 DAC (found here: http://www.filefactory.com/?1b27e7) I don't think there's a need to use a I/V resistor, so I left that out. The actual Lundahl configuration I used is here...

I'm looking for an online website for downloading lossless audio of Japanese music (like Paris Match and The Pillows) and I can't find anything. iTunes has stuff, but 128 AAC will get butchered by my setup nowadays. Are there any websites that have lossless or 320 kbps MP3 options? Buying CDs...

Hey! I'm modding a CD player, and need some help with a few things. The schematic is here: http://www.filefactory.com/?211295 Based on the schematic... The opamp will be changed to two AD843s with an adapter (socketed of course). The muting transistors have been removed (no audible...

Hey all! I have come to the conclusion I'm looking for an upgrade from my MS-2i's. I love the Grado sound, (or maybe something similar...) so would the RS-2 or RS-1 (or another) be appropriate? Would it really justify the money that would be spent to upgrade? Your inputs are very...

Anyone know where to find these inside the US? I've looked far and wide and to no avail... ~Tom

Hey! Attached is my (with the help of Garbz in some cases) DAC design! At the front end, is Jocko Homo's (of the diyaudio forums) S/PDIF input circuit. Then, that goes to the two inputs (input + and -). There it goes to the CS8416 input differentially. Afterwards, it then goes to the...

Just a quickie, do I need to tie anything to the RST pin or any external circuitry for the RST pin, or can I just leave it there and it'll be fine? Thanks! ~Tom

I have a question. I'm making my DAC and I've come upon a problem. Based on what I've seen in the datasheet of the PCM1792 (by TI) it requires 5 volts for the analog supply section. Do I plug 5 volts in, regardless of current, or do I have to step down the current *using a resistor, I s'pose* to...

I wish to connect an AD1896 ASRC to a PCM1792, and I just can't seem to figure it out. I know how to connect the SDATA and LRCLK, but I can't seem to figure out what to do with the SCLK output and MCLK output, as there is no MCLK connection on the PCM1792. Basically... SDATA -> DATA LRCLK ->...

I'm currently building a DAC, and need a nice I/V converter and differential to single output. The sequence is this *of my DAC*: CS8416 -> PCM1794 -> ???? (I/V converter) -> differential to single outputs *or visa versa* I thought about op-amps, but saw this: K&K Audio Which is too...

I have quite the conundrum. I want to build a very nice amplifier, but cannot decide between an M3 or Dynahi. Does anyone have any experience with both amplifiers? Namely, how do they sound when compared? I want to build a beast, so if there are any more designs I should consider, go ahead and...
