SME 20/2 SME V or Triplanar VII?

Thanks for stepping in, Doug.

Also, note that the rule of parallel resistors applies, but in the case of two largely different resistor values (like 47K and 500 ohms), the net parallel resistance is for all intents and purposes that of the lower value resistor.

Thom's right about dual paralleled resistors, which I did use extensively with my stepups. The math is easy though.

Dgad,

My MC phono stage is also solid state, so those numbers should put you in the same ballpark as me. (One possible difference is the native input impedance on the inputs. Mine is around 1500 ohms without any resistors, FWIW.)

If you're referring to break-in on the UNIverse, my experience (with four of them) is that they made most of their progress in the first 5-10 hours and changed very little after 20-25. They were bass- and dynamics-shy OOTB, but they opened up and then stabilized very quickly.

No other cartridge I've had broke in so quickly and easily. The Airy 2 needed 75+ hours to open up. OTOH, the Airy 3 needed 150+ hours to calm down. The Shelter 901 needed 300 hours before it stopped sounding like nails on a blackboard.

If you're asking about break-in on the resistors I have no idea. Considering the levels involved, it's probably decades!

I hope things go well with your Dad...I will have you guys in my thoughts.

Thanks Larry!Very nice sentiments,but having had the fortune of meeting you I am not surprised as to the consideration and concern.

Best!
