Legacy Aeris and amplification.

@zephyr24069 and @tmcdade which pre-amp where you using with Aeris.

Which McIntosh do either of you recommend?. I am consider class D options like ATI AT543NC, Nord. Class A/B like Coda, ATI, Adcom etc. How do Class D perform w.r.t to Class A/B with Aeris?.

I just don't like McIntosh since they don't double the wattage when using 4 Ohm output compared to 8 Ohm. 

Any suggestion and help is appreciated.

@zephyr24069 interesting way to go full range. Going to use wavelet for the system ?. I did hear the Caliber XD at RMAF.
