They both employ the same class A/B MOSFET output stage, but the SIA2-150 features a larger power supply.

No plans at the moment.

Hi Romulus, Based on the Simaudio Moon 240i specs (from their website), the SIA2-100 offers more power into both 8 ohms and 4 ohms. I can't really comment on, "Naim amp" unless you advise a model(s) you are interested in. Edit. I've found some good data on a comparable Naim amp, the Supernait...

The SIA2-100 has two transformers: one smaller toroid with multiple secondaries for preamp, DAC and logic functions and one larger toroid with two secondaries for each power amp. No, the Grounded Source topology is not unique to us and you correctly identify that Hafler used it (quite...

Hi Andy, The improvement we have made reduces mid and high frequency crossover distortion and also results in a lower bias current which requirement which, leads to a lower operating temperature. A win, win! They don't come around so often! Kind Regards, Ben

Hi Merlin, We'd be interested to hear what you didn't like about the ATC amp packs? If we didn't feel they were match for the vast majority of other comparatively prices amps out there, we wouldn't build them. The largest limitation in passive loudspeakers is the passive crossover. It's...
