I'd go Aleph, the Spectral, then Levinson, the Bedini has no comment as I've never heard one. The Levinson last but by a smidgen, not a whole lot.
Interesting... The Bendini 25/25 is the real SCORE on that list, but also quite rare on the used market as the original owners will never sell them. A very sweet and articulate amplifier and my all time favorite sand amp. The original 25 watt Mark levinson ML-2 monos should be a consideration as well as the original Krell KSA-50.
