Newbie to this forum, but I’ve had, and loved, my Aerius i s for 20 years. I had however relegated them (reluctantly) to my less-used ‘analogue’ room when I installed a Linn HT system, as the Linn amps simply do not work well with the MLs. I’ve now however switched to Arcam amplification (AVR20) and the Aerius are back in service and sounding good (bi-amped from 4 channels of the AVR20). I have however come across a pair of Spire at a reasonable price - I won’t be able to go listen to them until next weekend, but has anyone made this change and what are your thoughts?
