Can highly recommend All Ears suggestion of Luxman L507uxii. RRP £5800, but £5000 from Nintonics. They also gave a generous trade in on Marantz PM14 and have a personal delivery service so no DPD lottery. Mine had JAL air cargo stickers, so no weeks in shipping containers crossing the equator twice! Sure the AS3200 is a fine amp. Both analogue class A/B with VU meters. Still the way to go, imho.
edit to add.. I had MA floor standers, 952 gold and studio20 se for 28 years. Don’t see why they would not pair well.
