This thread continues a side discussion started in:   Tiniest Portable amp I can build   So, I was out running errands, drove by Radio Shack and figured I would pick up the parts to make nikongod's micro-transformer impedance step-down box. $12USD and change later:     I went...

While Thanksgiving is a mostly North American holiday, the sediment remains universal; giving thanks for family, friends and the abundance we enjoy.   I am thankful (and fortunate) for all of the above as well as all the great times, amazing camaraderie and wonderful music this forum has...

Hello all,    Having no reference for what a "real" set of Toshiba 2SC2238/2SA968 parts look like, I am hoping one of our more experienced members who may have actually worked with the part can lend an opinion.   I have two sets I recently obtained, the first, from RF Parts with no...

Okay, it doesn't get any cheaper than this, so, no excuse not to own at least one functional multimeter. Harbor Freight is offering one of their already cheap multimeters for FREE with any online purchase. Not sure if they will honor the deal at their stores or not. The meter in question...

Okay, I am slightly confused.   What, if any, is the difference between the Westone Pro Audio line and Personnel Listening line? The products look identical yet one is a "Musician's Monitor" while the other is a "Custom".     Different cables perhaps? Any ideas?   Thanks!  

Okay ladies and gentlemen, I need your keen eyes and vast experience to help me determine if these are counterfeits or the real deal!   These are Toshiba 2SC2238/2SA968 parts, supposedly sourced from Japan.   Take a look and let me know what you think!!       Thanks!!   jk

So, I needed a "warm up" project to get back in the DIY mode. It has been more than a few years, but, I used to do this a quite bit back in the day, so, it was more of a matter of climbing back on the horse than starting from scratch. I needed a simple switchbox. I wanted it passive as I can...

I realize that the topic dejure is the engraving mistake, but, there are a slew of us that are REALLY interested in the sound quality of these phones. In particular, how they compare to other Grado models folks might be more familiar with, say, like the SR225? ;-) Thanks in advance for...

So, my wife asks me, "What's the big deal with those tube thingy's you spend so much time listening too? Why are they so much better than my iPod?". Then I stepped in it. I told her to get her favorite CD and I would show her. I haven't gotten NEAR my rig for two hours now. She wants...

Okay, I have seen conflicting opinions on this subject. When wearing bowls, should they sit on the back of the ear or attempt to encompass the ear? I have been going back and forth. The bowls do a pretty good job of covering my ears if they I allow them, but, I think the overall sound is...

I have built a simple passive switch box and went back and forth over using a 4-wire braid (left signal/left ground/right signal/right ground) vice just using shielded interconnect cable for the audio signals. I ended up going with the braid for a variety of reasons, mostly convenience of...

So, whenever I want to show folks what makes a Grado sound so different from other phones, I always choose one or two songs. In particular: "Master of Sparks", from 'Tres Hombres' - ZZ Top The remaster of this disc is particularly good and sounds great regardless of amp! Heck, it sounds...

This is long, you have been warned! ;-) Okay, so, I had to scratch the itch. I had to hear what tubes brought to the table prior to going forward with another solid state amp. I figured I would never forgive myself if I did not at least give them a chance. So, what to buy. SO much to...

Hello, I need to build a simple selector switch box to switch between audio sources. Can anyone recommend a switch part that is of good quality that you have used successfully in the past? If you can include the vendor and part number as well, that would be great! Currently, I only have...

This question is for all those "multi-amp" folks out there. Since most headphone amps have only a single input and no "loop" output to daisy-chain additional amps, how are you controlling/selecting the output from your sources to the various amps? Passive selector switches? Active selector...

Has anyone heard both of these amps to offer an opinion? I am considering both of these and am curious to the relative differences between the two in terms of sound quality. I will be using both low and high impedence phones with a large variety of musical styles. Any impressions...
