Accuphase E450 vs Pass INT150


Hi looking for an amp to power 4ohm PSB Synchrony Ones.
Want something with a combination of body in the mids and a tight bottom end, and not clinical on top as the speaker has a metal tweeter.

Considering these:
(1) Accuphase E450
(2) Pass INT 150
(3) Plinius Hiato or 9200
(4) Simaudio 600i
(5) ATC SIA-2-150

Thanks for your help

Forget to mention I can't get an Accuphase demo here, but I can demo the others....
There are numerous choices that compete in this catagory. Most sound great, and most are crimInally over-priced. If you have an Anthem dealer, try the 225. Its scary resonable, and sounds as powerful, and as organic as anything I've heard in a decade...Great speakers!
Will look out for the Anthem, I suspect it will be $3000 here.
My bank account is heading towards the ATC amp, a lot of favourable reviews out there. Interestingly enough its only $3400 here.
Found out I can get the ARC DSI200 for about $6500. SOmehow I suspect the one I heard was not fully broken in as it sounded quite clinical compared to the pass.
Between the two, the E450gets my vote.
The Luxman 505u are also very good for half the price of the E450.
