Phonostage Burn-in to keep unit sharp

Why wouldn't the manufacturer burn in the equipment before shipping.
That way, when you get the item, its burned in. Well, you know the answer know, don't you?

Would using CDP as a "phono preamp cooker" not fry the preamp with it's 2V (or higher) output? Especially when CDP is connected to the preamp input for low output MC carts. If that is not an issue, then I'm gonna do that. I promise not to use the requiem thing for this purpose.

Be careful here, Chris. I do believe that these devices such as the one Hagerman builds has a circuit board that connects between the CPD and the inputs on the phonostage to drop the signal strength many fold. This is to prevent severly overloading the phono stage circuits. I prefer just playing records to burn stuff in, but if you want to speed this up with one of these CDs, that't fine. However, do look into purchasing one of the products mentioned in the original post.

Dazzdax, yes you can damage the phono preamp with the normal CDP output!!!

It can be avoided by using the Ganite Audo Phono Burn-In & RIAA Test CD (Model #CD-101.1). This CD is specially recorded with the RIAA Frequeny Curve at 4mv for playback through the phono input. This simulates the output level and signal of a MM or MC cartrige.

There may be other products like this as well. I just happened to run into this one at CES.

Correction: It is "Granite Audio".
