I have the Atoll IN 100 SE (latest version) recently. Used with a Marantz CD player and speakers 6003 Monitor Audio RX1
. A remarkable transparency, certainly superior to many much more expensive amps. The secret? A feed is 660 (two power supplies of 330 is because it is a dual mono), where the dynamics and transparency ... and 11kg of the beast. I see no other model with such a power supply at that price. Contrary to other opinions, I find that the options are a very good idea because you only pay what is needed. For my part, no remote control (which I find useful for a CD player, but not for an amp), no phono card, no card dac, but the optional aluminum facade rather than black for € 40. € 805 in total, port offered by CTA Perception. An excellent deal.
