<font color='#000000'>Just installed my daughter's Onkyo TX-501 AV receiver. Her DVD player only provided Optical out & no coax so I bought a Monster cable optical link. The connection to the receiver is very tenuous. There is no satisfying "click" when the optical cable is inserted -- it just sort of rests in the connector instead of latching on. Moving the receiver, even gently, frequently dislodges the connection. There's even a 2nd optical input on the receiver so I doubt it's the connector there. The Monsterlink cable looks good. Is this a frequent problem with these optical cables?</font>
