Sonic Frontiers SFP-1 Upgrades


Hi all,

I was wondering if anyone has done the parts connection upgrade to a Sonic Frontiers SFP-1 phono section?

I demo'd a Graham Slee Gold Mk. V and was very impressed, so I'm waffling over modding the SFP-1 or selling it for the Slee.

Any opinions would be appreciated.

Thanks

Among other phono stages like the EAR 834 and the Wright Sound WPP200C, and building a K&K, I am also considering the Parts Connection upgrade to my SFP-1, and am hoping someone out there can comment on the results.

Per PC "The SFP-1 ws deisgned in 1992...wsa current until 1996....the paprts quality chosen was CIRCA this period, and on a tight budget....the parts we have now chosen are more fitting for a circa 2006 $3500 to $5000 phono stage."

Per the parts list, the upgrade includes 13 capacitors including a 75/400V - Solen power supply cap, 26 resistors, internal wire, and 4 semi-conductors. The transformer is unchanged. Installed at a cost of $675, upgrading to teflon caps raises the price to $1000.

Upstream is VPI Scout and downstream is a CJ CT5. Thanks.
Thanks for the response - it sounds to me like it is not worth the $ to upgrade to a Phono 1, unless Chris tells me that todays's upgrade takes it beyond the Phono 1. Any idea how many years ago your friend upgraded the SFP-1. Every compare with the Wright Sound phono stage?
Emailed Chris and he confirmed that the SFP-1 upgrade is a straight parts swap, not a change to design. So, that makes sense that the SFP-1 upgrade sounds more or less similar to the newer Phono 1. Thanks for the help.
