The Belles Aria Signature Integrated Amplifier

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.
IMHO

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.

msafrick - As a Rogue Audio Sphinx V3 owner I would like to hear more about the comparison with the original Belles Aria. The V3 is an exceptional integrated with a killer phono stage, IMHO.

i am curious to hear from users who have the aria sig and formerly the regular aria whether the sonic character and tonal balance of the sig unit is appreciably altered from the regular aria
