I also had the Aleph 2s with Dunlavy 4s. I went from the Aleph 3 to the Aleph 2s on the Dunlavys. I thought the major improvment was in the bass going to the 2s. There was always something I liked better about the sound of the Aleph 3, there just wasn't enough power for the Dunlavys though, and even the Aleph 2s with the Dunalvys wouldn't rock the house. I consider the Aleph 2s to be a weak 100 watts. They are great sounding amps though, just not powerful sounding amps.
Pass Labs Aleph Question
Was thinking of trying out the 100 wpc aleph 2's with Dunlavy 4a's. I've heard these amps are some of the most natrual sounding amps out there and was wondering how well they performed in the low frequency area. Are they bass shy or can they be authoritative? How do they sound with complex music ? Rock? Thanks
