Hi there, I'm new to the forum.  I finally took the plunge and decided on XXHE as my player.  Thanks, Peter! 

Great player, but I have a few questions :-)

My question is:  What bit depth are the upsampling modes running.  Is it fair to assume that it is interpolating 16 bit data to 24 bits and that any dac less than 24 bits will be truncating the output?

Do I understand arc prediction correctly?  Is it keeping all the original data points and adding new samples in between, but not post filtering the final product? 

Has anyone used a hardware upsampler/digital filter after arc prediction and liked the sound?  I can only output x4 from the Hiface Evo and I can definitely hear the image in NOS.  I tried the 3 filters in XX and the sound differences are major.

Thanks,
Greg
