Dear Jwglista: +++++ " you will alter the sonic balance away from what the cartridge manufacturer originally intended " +++++
IMHO every cartridge design reflects the designer preferences/priorities and normally the cartridge voicing is made taking in count those preferences and a quality performance level, of course that in some models the designer has to make some trade-offs on his preferences for commercial factors.
In any case and specially on the expensive cartridges if any one like the original cartridge sound we have to pay for it making the re-tip through the cartridge manufacturer, this is what I do always.
I can't think to send a Xv-1 or KRSP or MC7500, Titan i or Orpheus to any re-tipper people like SS, no way.
Of course that I can d it but IMHO the cartridge that I will receive with the whole re-tip job will be a different cartridge where the designer hard work ( research, voicing, selecton of parts, the design it self, et, et ) disappear in favor of what?.
If you speak with the re-tipper people ( I already do with at least three of them ) they say that we don't have to worry about that their work is first rate and that the cartridge will " sound " at least like the original and better yet. Well all them are promoting their commercial job.
Do you think that is true? do you want that your cartridges ( example ) on the 5K-10K price range " receive " for 500 dollars a re-tip other than through the original manufacturer only because is a low price and the promise that maybe it will sound better?, well I don't take that risk, do you? it makes sense to you? anyone?
IMHO I don't think that that re-tip cartridge alternative is like the tube rolling exercise. Well this is only an opinion.
Regards and enjoy the music.
