I have been building various cmoy amps and I've built a bantamdac. I thought I saw that the PIMETA v2 boards were available for sale. Is it true? If it is, do you think it would be a good next project for me?

I just picked up a Sony D-133 from goodwill today. I put some batteries in it and it works fine. I tried looking up online for specs of this portable cd player but couldn't find any. I picked it up because it has a line out jack along with a headphone jack. It sounds nice especially with a...

I found this article interesting, because I went to college in Utah. ksl.com - Burger war about to heat up in Provo I really do like In-N-Out, it is one of the places where I can get a single hamburger without onions and have it wrapped in lettuce (Protein-style). It is also pretty good for...

Wow, I just finished my very first BantamDAC. It took me a night and a morning to complete. For troubleshooting I first I had to reflow the TPS regulators. Once I did that I had the correct voltages. Then I had to reflow the pin legs of the PCM2702 DAC chip (I had a pulsating static sound and I...

I've never listen to these headphones before, but I've seen them at the store and I see a lot of the kids around town listen to them. FWIR in the forum, skullcandy doesn't sound as good as they look. I found this article online about skullcandy and them being the #2 headphone company after Sony...

I have searched the forums and I am planning on buying a pair of Grado headphones. FWIR, I think the 60i or 80i is what I am looking for. I live in Arizona so I am able to get the grados for a good price from amazon (as opposed to living outside of the US). I was looking at the MS1 but I already...

I just finished building my second Cmoy and I was wondering which resistance to use to figure out the frequency of bass roll-off. I am using a 10k pot and have 100k for R2. Which do I use in the formula, f=1/(2 x pi x R x C)? Is it 10k from the pot, 100k from R2 or is it something else? (9090?)...

I recently built my first Cmoy amp as my first DIY amp (first time soldering anything significant, I think I destroyed the soldering tip) and I made a mistake when ordering the LED. I ordered my parts from Digikey and I used 160-1780-1 instead of 160-1708 LED, lol. Well everything seems to work...

This may be a dumb question but can a static electricity shock damage your headphones? I was listening to some music and I had on a sansa clip and a yuin PK3 while I picked up a bathroom rug. I felt the shock of the static electricity go through the rubber earbud cord (against my shirt) and it...

I am deciding on buying a portable headphone or earphone. I already have the Koss KSC75 and I really enjoy them. I think they are a great value. I am thinking of either getting Yuin PK3s or Head-Direct RE2/Fiio E5 combo. My source is mainly an 8GB Sansa Clip/KSC75, and I sometimes listen to...
