Millet max as a preamp? schematics disclosed

[acold7dusta]

Hey guys- I built Pete Millet's Hybrid headphone amp about 2 years ago, and i must say it's a great design and sounds great through headphones. It has been stated that it can also be used as a preamp, as well (although I don't know of anybody that does this). I have just finished building a pass F5 amp last week to power my thor's and using the millet max as a preamp (through the headphone out to RCA).

I guess since this is my first seperates system (had some receivers before) What sort of things should I listen to, to know if this will be suitable as a preamp? Don't get me wrong-it sounds great, but before I modify the millet max case, I want to make sure that this is a proper way to go.

It would be perfect to have a headphone amp that can be used as a preamp as well (to cut down on boxes + easier integration), but if that isn't the case my next project may be an aikido.

Thanks and sorry for the long post,
Kevin

Well, that's about it! If it sounds great then use it as it is.

Then, when you have a functioning music system, you can decide if you want to spend time and money trying to better it. I mean by building an altrnative, so you can then swap the new one in / out without having to rip apart your existing one, hence always having music available to you and having a known reference against which to judge 'improvements'.

If you find that you can only use a small part of the volume control you might want to build a second one without the gain tube, just a volume control and output ('diamond') buffer.

Perhaps others will be able to offer alternative ideas...
