I own a Jolida 100A that has upgraded Electro-Harmonix tubes and a Sony SCD-1 modded to include the super clock 2 and a transport mod. The Sony is sweet sounding, has more air, better base and a lower noise floor. I originally bought the Jolida for a second system and moved to the main system when the Sony went out for repair. The comparisons were done after level matching by measuring the voltage accross the speakers terminals. It's probably not fair to compare the Jolida to a SS player costing 5 times its price, but the Sony is clearly more musical playing Redbook CDs.
