    Topping L30 Headphone Amplifier Review

    Douk HiFi 6N3 Vacuum Tube Preamp Review

    Hi if to get a good amount of 2nd order distortion is the goal there could be a much easier way to obtain it. I am not an expert in electronics but a one bjt single ended no feedback line preamp shoud provide a distortion spectrum very similar to this one under review. I mean should...

    What cables do you use in your systems?

    Thank you very much for your kind and valuable reply. But it seems to me weird to look for speaker cables with the section of a water hose that end in a hair thick voice coil. By the way i followed some DIY discussions about replacing headphones cords. In some they are very very thin. There...

    Hi i think you are very right. It could be a result of overprocessing used for producing digital masters. There is a very simple way to check that ... to make a decent digital copy of a high quality analog tape and compare the original to the copy on a high revealing system. If the copy...
