Audio Research SP9 MKI tweaks


Hello,

I would like to know if there is any known and documented tweak to upgrade the SQ of my SP9 first version, I seem to recall the MKII is not just different components but I might be wrong.

Do you have any suggestion for updates to improve the SQ?

 

Thanks

Hello DeKay, 

I have to figure about the PSU for caps, never thought of those and for sure if replacing the old caps, which won't be anymore to original specs, can help why not, it won't be a bank breaker.

 

Thanks for your suggestions

Ciao Sns,

I too wanted to add an IEC socket but back in time my tech, another one, suggested to leave it as is not to depreciate it, what I'd do if I have the caps replaced is to upgrade the power cable with a new one and a better plug even tho I am a firm believer that cables only influence psyche not sound quality...

 

Hi Jason, 

I understand the SP9 was a mid ground in the AR lineup, I don't think investing in an upgraded vintage would be much of a help for my setup, I rather make the best out of what I own rather than swapping, here in Italy the SP9 sell for 1K and over, I can't imagine making that money out of mine nor I can imagine finding an SP10 for a reasonable amount

 

Thank you everybody
