  2. Post the last thing you bought!

    No worries, if the price you paid isn't a screaming bargain it's the real thing for sure. That's the other detail helping to spot fakes, the prices are always too good to be true. Moreover it'd be a new strategy of those scammers selling the gear directly from the destination country and not from China or any other far East country.

    I didn't want to make you concerned, just kidding a bit. The picture showing such mint unit brought the idea into my mind, but I don't think those chinese copiers have gone this far yet.

    Are the Chinese copying AR stuff now? :kitty:

    ...

    I'm very afraid they are. I saw on Ebay one of those stores based in China selling "Audio Research-like" cases for electronics projects. The damn case was as a perfect reply of an AR as it can be, but for the AR brand prints. I guess that making the whole thing won't cost them very much and there's a lot of profit in it for them :palm:

    Hopefully yours is the real deal, I don't think they'd go as far as faking the serial number plate, using as good quality connectors as your pics show, and having all the bolts perfectly flat and minty. I guess you can catch the fakes on those details.

  8. Happy Birthday to...

    Yeah, it's a weird little superstition I've developed -- if everyone misses my birthday, then I don't age that year.

    I haven't been able to test it yet, though -- not a single birthday has passed that someone hasn't wished me happy birthday.

    LOL You won't cheat the time going by. However it must be nice trying ;) Good luck this year.

  17. Some Test Results (SE vs Balanced vs Portable SE)

    in Headphone Amplification

    You know what I think you're right :palm:Sorry about that! I had been convinced (by myself) of what you were saying and then convinced the other way (again by myself) but with your mental picture I think you've settled it in my head ;D Sorry again that was dumb of me :palm: :palm:.

    I still think it's a measurement artifact though since the difference is on the order of the 6dB that occurs when you go from balanced to SE. That and when I did the tests it didn't show up. The floor was actually a little higher for balanced because each amp was working at a lower gain and hence the noise floor of the amp was at a higher level.

    hehehe, when you made your comment I thought you were right, but then I tried to imagine the picture of the driver working fed by a balanced signal, and I realized that what it was doing is actually converting the balanced signal in SE motion, so the common mode noise is probably rejected.

    I think it's very difficult to make valid conclusions from those measurements. You could be also measuring the noise difference from balanced to SE into the own amplifier or even the source if they're using SE or balanced outputs from the generator. Your take about the noise floor being lower for having a doubled voltage signal seems quite valid as far as the noise voltage doesn't get doubled too. If it's common mode noise, I'd expect it to be lower nonetheless.

    How is output impedance on the amp affected by using SE or balanced outs? My guess is that it's higher, so you'd be lowering the damping factor, which could have audible and measurable effects. Funnily enough on our measurements on the HD600 we didn't notice any change on impulse response nor in the bass response.

  25. Leica M8.2 or...

    in Miscellaneous

    If you like the Leica lenses and cameras, check out Panasonic cameras. They use Leica lenses and often you can find the exact same camera for a lot less. You just can't mind it being labeled "Panasonic" rather than "Leica". :D

    Very true, thanks for the reminder, I've seen some of their Lumix small cameras displaying the Leica logo... I'll check them, they might have a model which is the size and versatility of the M8. I love adjusting the camera the old style, without having to run through uncountable menus and submenus. Just choose the ISO then combine speed and diaphragm by rotating two wheels to get the desired depth of field or quickness for moving objects, and decide if you want some over or underexposure. Clean, clear and fast.
