Sometime ago I purchased a Onkyo CR-315DAB hi-fi unit, which came with a pair of D-N713x speakers. I have only seriously started using the system recently. I find the sound generated by the system very average and I don’t know if the unit is the cause or the speakers. Does anybody know if this system would be better suited with say the Tannoy F1 CUSTOM speakers or should I replace the whole system with something better, I am on a very limited budget. Your help in this matter would be appreciated, I am certainly no expert in hi-fi systems.
