If you do not use analog inputs, several dacs are available which have a volume control. This eliminates the need for a preamplifier. I have a wadia 321 which does this however does not have HT bypass. I think the (Wyred for Sound) Dac 2 is an example that also has HT Bypass and volume. A preamplifier containing a dac would also work. The Peachtree Grand Pre is an example that has a dac, preamp and ht bypass. I'm just surprised there seemingly are not more to choose from.
