In this case they mesh beautifully. There was a review in Stereophile many years ago explaining the design work done by Robin Marshall. If you don't have the opportunity to listen first it probably wouldn't be prudent to go with such an old design as the ES-14. But if you like large scale music and can afford the space for them. they're great. When I first got mine (off Audiogon) I drove them with a Naim 150. There was little too much tizziness on some recordings. I wound up getting a Naim 250 and they sounded terrific. Voices seemed perfect to me. You need the dedicated stands and they're ugly, to be sure. I really like the Motive 2s I have now but miss the bigger scale capability of the ES-14s.
