Has2be has a point BUT I'm betting you will know if the tubes are better or not even with the extra connection.
Tyi them with the sockets. If it indeed sounds better, you could consider something more drastic as Has2be suggests also.
If they don't sound better, don't even think about if it's JUST because of the sockets (it won't be), sell the tubes and move on.
