Ask Axiom for the frequency and phase response curves of the LFR serial number you purchased for the SPL range you'll be listening to. Then send these to Emotiva and ask them to evaluate if their XPA5 can remain stable across the SPL and frequency ranges.
Or just skip that and buy the ADA from Axiom. I trust Andrew did his homework.
In the above, I should have said impedance response curve instead of frequency response. You want to find out if the XPA5 can remain stable across that impedance response for all sound pressures of interest.
