Integrated Amplifier with the Good Bass and Extended Highs

I agree with glennewdick - Luxman is more affordable than Accuphase and actually may be even more affordable with their new US distribution. I have not seen the new price list but I am certain you can get a new Luxman integrated for $6,000 or less. I have owned both brands and Accuphase is better sounding. If you are smitten by the characteristics of the E-470, you might be a bit disappointed with the Luxman integrated sound (a bit more polite that Accuphase). Music Direct sells Luxman and they offer a 60 day money back guarantee. It might be one way to go!

That's exactly the problem. As I mentioned in posting, I shouldn't try Accuphase. I did try Luxman 505ux.. Believe or not, NAD C275 with the Rogue Audio Perseus pre amplifier sounded better then Luxman but with lack of the highs compared to Accuphase.
How about Simaudio 600i and PSB Synchrony.

600i is awesome. Also Odyssey Khartago Extreme

The new Yamaha as1000?

Consider Peachtree Nova300.  Plenty of good reviews, seems to be good bang for your buck.
