@sls883 I can probably reduce the distance a bit. I reached out to Doug Dale via email but haven’t received a response, so I’ll try calling the number listed on their website today: https://coda.cc/contact.
At this point, I’m considering changing my order from the S5.5 to the #8. While only the first few watts operate in pure Class A, it then provides significantly more power in AB. Given that my Pulsars aren’t particularly efficient (83.5 dB), I’m concerned that I may have invested a considerable amount of money in an amplifier that won’t deliver sufficient power.
