    Balanced version upgrade of the GR70 headphone amp/preamp.

    Phono preamp

    I think any new Fosi phono pre-amp should be a higher end MM cart only with just a low and high gain setting to keep it simplified and really geared to the task at hand....Add more things and it is detrimental on these small scale electronics. Strait RCA MM only with Hi/Lo gain switch maybe...

    Preamp Dedicated Subwoofer Preamp, for only subwoofers.

    What about a pre-amp that was dedicated for only subwoofer use? A lot of existing systems have issues adding a subwoofer, or DIY setups maybe it would come in handy. I use a regular preamp that just has a buffer stage to better control my subwoofer settings. I think you would want 3 pairs of...
