I own an older pair of Ascendo model Ms and although the speaker seems to function very well on amps of between 50 and 100 watts, much higher power really allows this speaker to breathe. I am a huge fan of Atmasphere amps but my concerns mirror your experience with this combo. Not a fan of class D but if you restrict this design to the low frequencies this might work well.
Integrated for bi-amping with AtmaSphere MA1s
My speakers (Ascendo ZF3s) have separate terminales for each driver. I am currently using Atmasphere MA1s for the mids and tweets, and using a Pass X1 and Aleph3 for the woofers. I'm also using a set of old Entec LF20 subwoofers crossed over with a Behringer Ultracurve pro for the really low frequencies. I would like to replace the X1 and Aleph3 with a more powerful integrated, and am not sure what to use. I've been away from this hobby for a number of years, but my first instinct when I think low frequencies is Krell. The S300i looks intriguing, but I've read that it comes from a dark time in Krell's history, and may not be terribly reliable, and not up to the stnadards of low-frequency reproduction Krell is known for.
Is this a good choice? What else should I consider?
