Nice and vague....Strawberries and cream?
Or oil and water?
Nice and vague....
Could we have more detail such as are you looking for a speaker for the vintage amp or the other way round?
As the Pioneer has 15 watts per channel specified and Spektor 1 are quoted on Dali website as recommended 40-100 watt amp, I would suggest not.
Unless you tell us what you have (amp or speakers) no one can help anymore.
Oil and water! A 15 watt amp with a 83db sensitivity speaker. It will be clipping at normal listening.
Do you currently own any of the two you mentioned?Thanks. I didn't request further help. You answered my question.
