The Belles Aria Signature Integrated Amplifier

I don't know when the I-30 was discontinued, but Primare's current offerings are I-15, I-25, and I-35, all of which, AFAIK, are class-D based.  A review in Stereophile or Absolute Sound called the I-35 a little lean.

The Primare I-30 from 2007, was replaced by the Class D I-32 in 2011

that is correct, the i-30 was the last class a/b primare - they went class d post the i-30 and the sound character changed... and not for the better according to most

@jjss49 ,
I have no experience with either Hegel or Naim, but I will say that the Belles Aria Integrated with a pair of Vandy VLR's (and with or without a sub) is a pretty sweet combo. In fact, with a Sub 3, it outperforms just about anything in the price range, and quite a few above.

Wine glaring weakness ,knowing electronics very well. Everything in a standard volume attenuator goes through it .. if you have a $25 alps pot it is just a 
carbon coated piece of plastic ,no getting around that . Any good preamp section 
is either a discreet electronic type with relays, or a shunt type resistive ladder type like Khozmo  ,or gold point . David B is a good designer 
to not address’s this and at $4500 not good.
for $4500 the excellent Luxman 505 mk-2  is noticeably  better then the 
$5500 McIntosh and well thought out throughout for something similar in its price class.
