Digital To Analog Converter Boxes

I have tried various ones. I keep end up going back to the Lasonic 260. The only bad thing about this one is it doesn't have many options on it like the others. The Lasonic does provide a clear crystal picture and has great detail. Anyone know why if I use a certain cable with the Lasonic it makes the picture look haywire? I can only use push on cables and not the screw on type of cable.
