Dear @lalitk : I'm sorry to insist and disturb you:
" On my last shootout with T+A and Dartzeel, I preferred the synergy between the Accuphase...."
As I said before good for you that your unit outperformed the very well regarded top Dartzeel elctronics but ( as you said ) after dozens of post you showed no single word about MUSIC and you will do some comparattion tests between all the units options you will have on hand.
The 650 outperformed the Dartzeel because?: better transient response? better tigth low bass? better mid-bass or low midrange? better dynamics and lower noise levels? better natural color of the MUSIC?, better resolution?, better harmonics or wider frequency ranges? better high frequency range?, using which LP tracks?
I ask again because outperforms the Dartzeel are " big words " and you follow staying " dead silence " about MUSIC ( not only you but all other gentlemans too. Only hardware. ) and its characteristics in a units comparisons.
