Really, the LFD is by far the best amp with Harbeth. An LFD with Harbeths, without the subwoofer is better than a Harbeth with any other amp with a subwoofer. In most cases, a sub is just going to confuse things, actually bring down the performance of the Harbeths. If you really need more bass, get the Harbeth Compact 7 es3. These are my favorite Harbeths.
