Hello Teejay -
I hope you enjoy your Line Drive and find a good amplifier match for it. When looking for appropriate amps, keep the following general recommendations in mind:
1) Look for a fairly high input impedance - around 47Kohm or higher. Anything below 20Kohm is not the best match, although it will work.
2) Fairly high gain is also useful (in the range of +26 - 30dB, for instance). You may see this expressed as "input sensitivity," which is measured in Volts. Look for a figure around 1 Volt, give-or-take a bit. Anything in the 2 Volt-or-higher range may not give you the system volume you would like.
3) Minimize the capacitance of the interconnect cables between the Line Drive and the amp. I suggest 1000pF (pico Farads) as a *maximum* in this connection, with less being better. You should be fine with most cables of 2M or shorter.
