Hi folks,
thanks for the replies! My question was a little poorly-expressed, what I was wondering is whether there is an input voltage that is too high for a Foreplay in regards to safety/longevity/noise. I previously used my Foreplay with a CD player, which I suspect put out about 2 V (didn't test that before I sold it though). It worked and sounded fine and the Foreplay gave no problems, so I also suspect that the Topping DAC would also give no problems with its 2 V output. The only downside was that I didn't get a full range of use out of my Foreplay volume control (Alps) as it was just too loud at the top end.
Now, the PC attenuation is an interesting consideration I hadn't considered! I'm currently using JRiver Media Centre to implement parametric filters to control for my listening room characteristics and a slight mismatch between the sensitivity of tweeters and mids. I use a Wadia DAC/preamp with my kit amp and speakers and the parametric filters are all cuts, no boosts. As a start I'll work with those filters when I slip in the Foreplay and Topping DAC in place of the Wadia. So, due to the cuts from the parametric filters the Foreplay should receive a signal from the DAC attenuated by quite a few dB. Hopefully that could be enough, but I could also put in an additional broadband attenuation to take the output back further. Great!
