I've been using Dunlavy Alethas for 5 years running and I am totally happy with them. They are the best purchase I've ever in made in hi-fi. If you can find them or the Cantatas, these later designs managed to be even slightly flatter in response than the older models (35-20kHz +/-1 dB I believe).
If you're a bass freak, then get a IVa or a V. The Alethas/Cantatas are hyper-accurate but won't play as loudly.
Your Pass gear will be a great match for any Dunlavy speaker. But be warned that the Dunlavys are so good that you will actually be able to upgrade your amplifier and immediately hear an improvement. I know it seems impossible, but it's true.
