phono stage break in?

Onhwy61 -- I realize this answer isn't very scientific, but since all phono preamps (or stages) have built-in RIAA de-emphasis circuitry, it stands to (my) reason that they should be "conditioned" by feeding them the frequency/amplitude distribution curve for which they are designed.

As a matter of fact, the supposed advantage of using the Granite Audio CD or the Hagermann unit (instead of the Cardas record,) would be that you could run a higher level signal through the phonostage than it would normally "see" from a (weak) cartridge signal -- sort of like cable cooking.

Nsgarch- thanks for your response. However, I am not sure that I agree with it, and I think that by just turning the unit on for as long as needed (without even an input cable plugged in), you are basically achieving the same goal...and, based on your rationale, you are actually "feeding" the preamp the weakest signal possible...allowing you to use higher gain.
I must say that these CDs always struck me as one of the most unessecery add ons that are out there.

Nsgarch, thanks for the explanation. I don't agree, but I see your logic. IMO any broadband signal feed into a phono stage at an appropriate level should work as a break-in device. Just my opinion and it's not like I've run comparative listening test on phono break-in signals.

Here we go again...no time to enjoy the journey, just that aching need to get there here and now this microsecond and to hell with and damn the torpedos how we got there.

One word: MUSIC

Components are DESIGNED to be listened to with real music, in real time, under real-use situations, not facsimile thereof or some contrived and imagined scheme designed to shortcut the process. If it's a good piece of gear, just use it properly and enjoy it. It will eventually "break in" whatever the heck that actually means. It already has most of the qualities inherent in its design, and chances are if it was manufactured by a quality operation, it was thoroughly tested and found to be well within its operating specifications.

There is no guarantee that whatever method is used will reveal the final outcome in the proper system context and listening environment, EXCEPT actual use as intended. This false break-in stuff is for the birds, distracts us from the music, remember that?, and just puts money into low value junk like break-in "burners," CDs and records.

Just play music through the component and enjoy the ride.

Now let me tell you what I really think. ;-)

Steve

Noams, the devices do break in much differently with a signal going through them, and not just a static signal. It needs to vary in amplitude and frequency just as the signal from the record will. Just turning on the unit with no signal does nothing except warm up the power supplies.

Steve, I agree with you for the most part. However, when it comes to breaking in tonearm wire I'm all for any method that will speed up the process. But this doesn't take anything special. All you need is a cheap cable that you can attach to the cartridge leads. Plug that cable into a CDP and the other end of the tonearm wire into the preamp and let it play for a few days. (Thanks Albert!)
