![]() ![]() 500 Watts in Your Pocket? Kinter MA-150 Mini Amp.See some videos below and be sure to subscribe to my YouTube channel to stay updated with the latest amplifier and car audio tests and demos. I have done some initial tests with the DD-1 and have been impressed with it's ease of use and ability to detect low levels of distortion. I think it's important to keep the distortion less than 1%, which should be inaudible for most people. As I mentioned above, not only do many manufacturers rate amps by "Max" output, they also sometimes use distortion numbers up to 10% for their ratings. The DD-1 will ensure < 1% distortion in my results which is great. I have MANY old school amps I plan on testing in the upcoming months. The DD-1 has proved to be an invaluable tool and will ensure accuracy in my amplifier tests. After seeing the AD-1 demo, I was convinced to buy the DD-1 to use as a tool in my RMS output tests. I've been watching eBay for a year or more hoping to find a deal on one of these THD analyzers so I could verify distortion during my amplifier tests. A bench version of a THD analyzer can cost MANY thousands of dollars. This DD-1 can be used for more than just matching can be used to assist in amplifier output testing! This feature in a sub $200 device is unheard of. A recent video on Steve's channel about the upcoming AD-1 "amp dyno" got the wheels spinning in my old school head. The unit's ability to match gains is a great feature, but I've had this ability with my Velleman HPS50 portable o'scope for a while.
