Techinics Sp-10 Mk2a break-in period

Hi Peter,

The custom PS on your sp-10 mk2, is it made with a captured power cord or is it fitted with IEC? Have you experimented with different PCs? If so, what are your findings? Thank you

Hello Norm,

IEC socket, and yes I do use various power cords - although I'm not subscribing to the theory that power cords make all that of a difference. As previously stated as long as the power cord is of sufficient gauge and the connectors / outlets are of a substantial quality, there is very little if any difference.

Good listening

Peter

I recently swapped out the skinny stock lamp cord on to the back of my SH-10EA PS for an  Furutech Cu IEC connector. I wanted to hear first hand if different PC used on the PS in this particular application makes an audible differences.  For comparison, I used a  $7.00 generic PC and a 2.0m Nordost Valhalla V1 PC.  I heard absolutely no difference between the two PCs.

 

Norm, Here's the thing:  The lamp cord, as I recall, is/was hard soldered to the PS.  Then when you ditched that you or someone else installed an IEC connector, to which you plugged in the Nordost PC.  In all my audio experience, NO connector has always sounded better than ANY connector, no matter how wonderful and Furutechian it may be.  Thus, if one were to posit that the PC makes a difference, the IEC connector might swamp out any such difference.  Here's where I admit that I hard-wired a length of XLO power cord (which happens to be my favorite) directly into the PS of my SP10 Mk3 and hear...... no difference.  But I felt oh so much better.

However, to my surprise, PCs to power the bias supply did make a difference to the sound of my Sound Lab ESLs.  Go figure.  In that capacity, current carrying capacity of the PC is moot; the bias supply requires very little current.  I generally think that sonic differences among PCs are 90% due to current carrying capacity, thicker is better.  But there are obviously other factors.
