if you wanted to spend a while researching, you could build a cmoy pretty easily for 30 bucks I'm using a jung multiloop topology amp (almost a meta42) w/ my dt770's hmmm though, I still haven't noticed an inability for my cdp's to power them w/ or w/o amp. no complaints here -Hype

Hmmm, I 've had a pair of these cans for a week now. And, w/o some sort of bass boosting, I really don't think the lower end is over emphasized. Thats from listening to mostly rock/metal this past week. I'll admit though, on a few rap recordings I can really relate to the talk about its huge...

on markertek's site, whats the difference between the 3.5mm mini-mini cables and the 3.5mm Balanced (Sterio) mini-mini cables? SC6MM - 3.5mm Mini Male To 3.5mm Mini Male Audio Cable SC6MZMZ - Balanced (Stereo) 3.5mm Male To Balanced 3.5mm Mini Male Audio Cable -Hype

OMG!! ROFLMAO ~ those are huge ^^; I feel better about the size of my cans now =] thanks for the help last few mins gerG

heh gotta love it I'm not sure how big the dt770's are in comparison, but they are bigger then I expected ;D I'm getting used to them though atleast you have a setup you enjoy -Hype

well if it wouldn't take too long that'd be great gerg thanks

Hey guys, I just got a pair of these this week, sound good so far. But I was wondering, should they have little bits of fuzz on the ear cups? Its like carpet fuzz for lack of a better example. And if yours had it when new, do the cups wear thin spots earlier than one might expect? Its only...

If you didn't split your voltage well, then a higher total volts would help it sound better, if not then I doubt it would matter. IE running off a 9v but ending up with -1.5V and +7.5V, the -1.5 wouldn't be enough to power the opamp and it'd distort. But if its 4.5/4.5 then it'll have enough to...

Sorry for hijacking your post ;P but does ad8620 come in DIP packages? I'm only seeing SOIC EDIT: bah nm I just read another post, needs an adapter -Hype

post part #'s so you can get some real help. those "2 connecters" on the side of the pot arn't connecters if I'm not totally off. Only the 6 in a row are. Search other posts on how to wire it. for the power switch, the (+) wire from your board goes to the middle pin, and the (+) wire from...

sounds great Probably a good step above my multiloop one ;P I got the dt770pro's shipping to me right now =] I think this amp will sound great with them. my next project is a simple low z mod linkwitz. the damn switch is half the cost of the whole project ;D but it should add another...

always check the opamp's datasheet to be sure, but for op amps like opa2132 and ad823, thats correct. Make sure you notice where the notch is, as that is *slightly* important lol -Hype

eh same problems I had with angelfire and geocities lol, lots of ppl completing amps lately gw -Hype

alright, simple enough thanks you two now I have a use for this penguins tin I bought =] -Hype

I saw that you were making your way around the posts voodoochili ;D Lemme see if I understand at all, put all the grounds to some common place on the board, then link the in/out jacks to it, and it uses the gnd from the amp?? that'd be easy if thats the case. how close(or off) am I...

I'm back for another round of noob questions!!!~ Now that my amp is done, I figured I'd add a mod. linkwitz xfeed into the picture. I'll be making it on the rshack 0150 board since I've gotten used to it. So I guess this thread comes about because of my total lack of knowledge towards...

I used wire clippers to get the excessively long wires gone, but my amp has a REALLY close fit as it is now... so the dremeling was crucial. It probably increased the chances of a bad joint, but non noticed so far. didn't think of nail clippers though ;D anyways I'm happy with my results...

I prefer the penguin tin personally T.T Looks like an amp from here lol. I'm glad it went smoothly, mine had a few problems along the way... I ended up pulling out the dremel tool to shave down the solder leads in the back so it would fit in the case This DIY stuff is really doable if...

lol faehntim, it is a nice layout isn't it ;D Thanks for the photoshop images of the board and parts! the images are visable on and off again depending on the bandwidth restrictions on geocities... I'm assuming since this post has been up a few days it'll quiet down some. I was worried my...

first problem found first problem solved lol It was working great last night when I put it away, but this afternoon when I tried it again, no music came out, only hiss. My best guess was the opamp wasn't fitted snuggly enough on the ic socket and when I was looking at the bottom side...

I was under the impression just divide R6 by R5 for a rough estimate for inner loop. heres power schematic and amp schem all in 1 image :P There arn't any LED's right now... but I've got a pack of 10 w/ me lol GL BTW: This winter has been hella weird. Today was the first day in...

looks like images are back up?? umm.. lets see R3 499 R4 4.75k R5 4.75k R6 887k I don't know the calculations to find inner gain, but total gain by tangents calculaters is 9.8928347928374928374982374827342 or something close =] R2 is 100k and I think R7 is 100 If geocities is...

lol What your literally seconds late yeah I kinda got a schematic, the resistor values are a little different than whats on it. umm... go to tangents meta tutorial, look at amp schematic and mines the same, except no R1, no biasing, no R 8,9,or10 local gain of about 187 I think and...

eh try refreshing :P I added links to the pics at the bottom if they don't load They work for me again Keep up the feedback =]

pics back up =]
