I recently traded some unused gear for a set of 8.A, and I need impressions made in the Dallas, TX area.  With all professional services, I like to have personal feedback before selecting a vendor.  If anyone has had excellent impressions made in the greater DFW area,  please send me a PM...

A while back, I rounded up my old, unused equipment: HD650, X-Can V8p, and a Denon AVR-2802 and passed them along to my 15-year-old step-step-nephew, twice removed - I think. It's complicated - too many blended families are at work here. He's a good kid with a rabid interest in music, audio, and...

As a physicist, I would like to continue my earlier comment by stating that uncontrolled tests with equipment of unknown characteristics may be leading many people to think they have hearing that extends into the inaudible.  This is bad science.  There is the burden of proof using real lab gear...

At work, the LCD-2 direct out of an iPad (have them on now).  Don't laugh - they work surprisingly well out of the humble iPad.  Better, in fact, than from some amps I've owned.  Perfect for low volume listening.  Try it, you'll like it.  I'm going to put a scope on the output to see when the...

I was a high school physics teacher for a while, and I would do this test with HP 203A oscillators, amps, and lab transducers - bear in mind that I did this with hundreds of students:   1.  HP203A set to 25kHz - I can't hear this at all - in fact, nobody can.  Have a mic and a scope to prove...

Quick window shot on a rainy day in Dallas.  Hard to arrange because my office has a bay window and no straight walls.  Nice because it looks out over the forest leading to Lake Grapevine - very relaxing.  The other listening station is in a window seat by the pool, with the amp sitting in the...

Koss ESP-6.  Perhaps I show my age.  There was nothing good about these - heavy, vice grip the likes of which only my ESP-9 was ever able to equal, and oddly unreliable electronics in each cup.  If you see these cheap, and think a vintage electrostatic experiment might be a good thing, don't. ...

The HD650 is just so comfortable - and I mean that both physically and sonically.  Looking to try out the LCD-2 to see how it compares.  

When the TSA becomes curious about a business traveler with 3 laptops, several amps, a bunch of wires, several sets of headphones, and a few IEMs.  When you need two security bins for just your audio stuff.

1.  Stax Lambda Pro - very light on the head, and just a great experience.  Drawback is the large electrostatic amp - can't move it around.  Sounds oddly different when lying down - they reposition on the head.  Clear and clean.  Cost a fortune when I bought them new so very long ago - although...

Bad day - the new puppy, at 8 months old, became confused and was uncertain if he wanted a chew toy or music. He found a way to get both. Not a total loss - he did find a way to open the case, so I completed the disassembly of the most-chewed iem using a scalpel to peel away layers. What was...

Interesting. Here's the folks who make the bass driver, according to the part number in the pics: http://www.knowlesacoustics.com/know...?product_id=28 Interesting data sheets for part No. CI-2955, for anyone who may be into that sort of thing. TC

Went out to an event with the kids (young adults, actually) a few days ago. Really hadn't done that in many years. It wasn't live - just recorded. Played some tracks I knew very, very well (every note), but with the bass all the way up. Completely ruined the dynamics. The venue probably had...

Take it to the next level: who can remember using one with a crystal radio? They were the cheap and available alternative to old 2000-ohm sound-powered headphones. No battery, just a bit of rock and the end of a pin, coil, long wire, and tuning cap. Built many of these and listened late...

Just so people can appreciate how far we've come: TC
