Audiofun,
I do agree with you on the need to take care on modifications to collectible equipment.
When Technics SP10 owners are contemplating the krebsupgrade they should be aware that there are legal exclusions of liability for any breakages incurred during the modification and that the modifications are irreversible.
I quote from the krebsupgrade website -
It is also of concern that no measurements or objective tests have been provided to support the krebsupgrade claims.
I have auditioned a Technics SP10mk2 before and after the krebs modifications. The SP10mk2 sounded smoother but gluggy after the modifications. According to krebs this "gluggy" goes away after several months, but owners should be aware that if they do not like the changes, the mods are irreversible. In my view the modified SP10mk2 is miles away in performance from a standard SP10mk3. In audio as is true in life there are no free lunches.
Comparing the krebs Technics SP10mk2 to a standard Kenwood L07D and replinthed and blueprinted Garrard 401; to my ears the Garrard 401 was superior to either the L07D or the krebs modified SP10. In particular the Garrard was more coherent and presented a more integrated sound through the whole musical spectrum.
I have also heard krebs own SP10mk3 on numerous occasions from when he first purchased it in the late 80's. I last heard krebs SP10mk3 about 5 yrs ago, certainly since 1995 when he first used the oil.
The krebs modified SP10mk3 to my ears has always lacked resolution, transparency and musical coherency compared to my Final Audio VTT1.
Apparently there have been further "claimed improvements" that remove the grey gunge, but I cannot attest to the veracity of these claims.
It is noteworthy that Artisan Fidelity in contrast to the Krebsupgrade has a complete list of modifications and test procedures for their SP10 refurbishment and enhancements on their website.

The SP 10 range in standard from is noisy, not in the conventional sense but noise which is a function of the music being played. There is also a tension, stress if you will, to the presentation and a greyness that over time is downright irritating.
I could not live with a standard SP10 MK 2 or 3. I don't have to, but I very happily live with my worked SP10 Mk 3.
Apparently there have been further "claimed improvements" that remove the grey gunge, but I cannot attest to the veracity of these claims.
