I have a Proceed HPA2 (Mark Levinson) amp driving Aerial Acoustics 7Bs and I love it. However, I have not compared the combo to much else other than a set of B&W tower speakers driven by the same amp. The 7Bs were way better sounding.
Not sure I would worry about an upgrade if primary use was HT though.
