Yamaha AS 501 is £399 here and Topping £349 from Amazon. For 'legacy' systems with RCA connections, I suspect the Yamaha may well be a better buy, but that little Topping is so cute though (I love the black with red trimmed volume control myself). Old-hand manufacturers really must wake up and acknowledge new designs like this as well as the best of yesteryear at this level (the aforementioned Yamaha which goes back twenty or more years under the skin I believe).
Can someone in the US please send Amir one of the Yamaha models or close ancestor to test? I know they've been 'done' by others, but an ASR-official test would be nice, even if it's only an ancestor 396/596 or similar, just to put it all into perspective. Not sure the AV models are related.
