I just got an Onkyo S3400 5.1 surround sound system.  I didn't even think about using it for my headphones for over a month, and it blew me away when I did.  Sooooo much better than my Headroom Bithead (yeah, I know, not hard to do).  But it definitely made me believe in night and day...

Thanks for your answers guys!  I'm going to lube it up and I heard using DeoxIT on the pots and switches might help.  If that doesn't work, than wuwhere might be right.  Ugh.

Hello.  I have a Technics SL-1500 direct drive turntable.  When it works, it works pretty decent.  But there's an issue with motor or something.  The speed is very inconsistent.  It speeds up and slows down at random.  I know a bit about electronics, and I know how to use a soldering iron.  I...

How bright were the tubes?  I had a quiet issue when I first built mine, and the tubes were super bright.  I had resistors mixed up. 

I bought a Technics SL-1500 off craigslist a couple weeks ago for $25.  It had a Stanton 681EEE cart on it, with stylus.  Well, the stylus was in terrible condition, and I ended up breaking it...is it worth getting a replacement stylus? Any help is much appreciated Thanks, Mike

Holy ****!  That looks amazing!  Congrats, sir.

    My amp is 95% finished!  I'm going go through, and redo some of the grounding eventually and maybe give it a new case.  Using the box the parts from mouser came in.  But for now, it's good.     I kept hearing this weird buzz every once in a while, and it was driving me insane.  I...

Yeah, and don't mix up a 33k and a 390k...you'll end up with it sounding really quiet for a while...than a tube will go out...

I used 12AU7.  I'm going to be adding LEDs soon.

So, I have mine all setup and it sounds pretty good!  I have to go through and rewire it with some better wire soon (waiting for solder to come), and some kind of better grounding.  Whateves.  But, one of my tubes is a good deal brighter than my other one.  But there isn't any channel imbalance...

My girlfriend's parents gave me $40 for graduation (feel free to gift me something as well  ).  Instead of saving it, or doing something useful with it, I'll just blow it on whatever sounds interesting that has been suggested in this thread!  So, link me stuff and in a few days, I'll buy...

Found out my issues.  Had the 390k and 33k mixed up in both channels.  Damn it.  Anyone happen to have a spare 12AU7? :p

I built the amp!  When I first turned it on, the left side was ridiculously feint.  After spending a while troubleshooting, I realized I had R7 (33k) and R8 (390k) mixed up.  Changed that and it worked amazing!   But I turned it off for a bit.  Than I came back and turned it on.  They both...

http://telecom.hellodirect.com/docs/Tutorials/AnalogVsDigital.1.051501.asp   Not a bad explanation.   Yeah, your prelude is your DAC and your Harman is your amp. Generally, the biggest upgrades are headphones > amp > DAC > Cables (if you're a believer)

Regardless of sound, they hurt like hell!  I honestly can't have 'em for more then 5 to 10 minutes before I have to take them out.  And my ears hurt for another 10 minutes after that :p
