DI boxes are supposed to have such high input impedance. 20 to 50 mv into a nominal -10dBm consumer type line input feeding a 24-bit converter could work fine without extra gain. You may need some extra 'digital gain' if the level of the instrument needs to be quite high in the mix. Ardour doesn't provide 'input gain', and its fader has only 6dB positive gain, but an amp or compressor plugin will do the trick.
