Hi @lalitk The A-2 is very nie. It was hardly optimized, replacing a Halo A51 with surround pre pro, stok ables everywhere and old B//W Nautilus 802's. but it shines!
I now have added an Elation PC, Auralic altair wifi streamer / DAC nad an elation Power cord. It shines already. smooth and sweet sounding, and plenty powerful. I am only there about every other weekend, so trying to not go nuts.
I have large HO layout I have been working on for years. I could pm you some pics...
