Looking at my blog statistics I noticed some visits on my now old and very dead Cmoy project. Out of respect for the people who are visiting I wanna give an update on my electronics projects. Since I built that Cmoy headphone amplifier and crossfeed my life changed quite a bit, I don't have the... Continue Reading →
Giving 5oo€ for a audiophile power conditioner sounds crazy but depending on the tech inside it might actually help prolong the lifetime of your Hi-Fi gear. Yes, I actually wrote that and I'm not joking. Archimago's blog has a great objective test and review about a power conditioner from a very reputable brand called Belkin.... Continue Reading →
Before wordpress, blogspot , facebook, myspace and livejournal there was a place called Geocities, on that place one could (and still can via mirrors) find lots of audio projects. If you enjoy some nostalgia do search for mirrors of Geocities or just visit the wayback machine. These day I browse the geocities a lot. You guys/gals... Continue Reading →
So the other day I gave the raspberry a little spin…still need to test the DAC. The mark on the TFT is just a sticker btw. Stuff I learned from the 1st hands on…Cold power off will corrupt the system so any power switch should be on the back panel. One shouldn’t mess around too... Continue Reading →
So I was reading some forum posts about the Raspberry/Wolfson combo when I found a jewel of a post, The people who write there show a lot of knowledge about tech and computers, so I’m sure they aren’t the typical “plug and play” kind of persons, but still these informed audiophile talk about “burning in” DACs for hours and...

So I got the the B version of the Pi and the compatible Wolfson Dac board. I also have a 12V 7" TFT that I’ll plug to the analogue video out because I didn’t find any hdmi TFT around my area. Besides that I have a shitty keyboard and a mouse for my laptop that I might... Continue Reading →
Did you ever noticed people looking at you in a strange way after you talk about your audio hobby to them? That “you are a crazy bat” look after we talk about audio gear or something related? I find it funny people don’t look that way when someone says they spend all their savings on a collectors car... Continue Reading →
I have a deep respect for the NwAVGuy work on the O2 amplifier and like so many other enthusiasts around the audio circle I wonder what happened to him, so I really wish he is well and happy. There are some theories behind his disappearance. NwAVGuy’s death or the death of someone near him, got a job on... Continue Reading →
Sometimes I really hate living in Portugal, If I want to buy some JRC4556 for my low impedance headphone amp I must pay 18€ of shipment doesn’t matter if it’s 1 or 30 op-amps, if the purchase doesn’t go above 65€ the shipment must be paid. I get people must get paid to make my shipment but 18€... Continue Reading →
Don’t get me wrong I love to build stuff but I draw my limit on selling clones, one thing is to sell a Cmoy amp the other is selling a RA-1 clone and actually using the Grado name to do it. I know that people need to make money but stealing a layout and making... Continue Reading →
I need to revise my cmoy headphone amp because that DC offset still bugs me a lot. I want to know what I did wrong or at least reduce the offset to an acceptable voltage 20mv to 25mv max. After some light reading my conclusion is that the problem can be from: A bad ground plane, a bad... Continue Reading →
When a designer makes portable gear he/she thinks about every little detail possible, the final piece is usually nice to the eye, easy to use and easy to get damaged. Enter the plastic (silicon) cover to the rescue. You got a amazing top of the line cellphone? Want it to last more? The cheap condom... Continue Reading →
