jon - indeed a digital device and/or passive preamp is often not robust enough to drive the particular cables and/or input section of the chosen power amp. Active preamps are designed for that chore to ascertain that the signal voltage swings will indeed arrive at the power amp's inputs. Some cables are harder to drive than others and long runs especially can deplete signal vigor.

The idea, what do you guy's think? https://www1.picturepush.com/photo/a/16067084/1024/Thiel-CS-2.4/CS-2.4%3ESE.png |
holco - good judgements, upgrading the signal paths. Coupla comments. Depending on your serial number and if it is Lexington-made and whether or not it is on masonite or a PCB, the .72mH woofer coil may not be the correct value. Details would help evaluate those particulars. Likewise, if it is Lex-made, the coil will look very tight and well-wound. If so, that is an ERSE coil which, in my opinion, will not be improved by the Jantzen, unless the J is foil. On the coax board, you are ignoring the parallel feed in the first position. I suggest investigating the 43uF cap and its 16ohm series resistor. At minimum replace that 16ohm with MRA-12s. Beetlemania might have comments on the other resistors. |
