Sugden, Accuphase or Luxman Class A Integrated?

I live remotely - nearest Audio is 4 hours drive away.
The Sugden guy is driving past this month so I can home audition the A21SE and the Masterclass Integrated.
I like Class A - great SET is only slightly better to my ears, and I listen to 90% acoustic music, mostly female vocals.
I will be upgrading my speakers too but that is another question for another time.
How do the Sugden integrateds stand up against similar Class A 30 watt integrateds from Accuphase (E-550) and Luxman (L-590A II).
I'd appreciate any views on these items - individually or comparatively.

in this order...accuphase, luxman, sugden......going class A in this catagory however will mean ignoring some of the finest, reasonably priced, and best performing integrateds out there, including luxman and accuphase.....a mac6900 is another one 'of many'.
Not as much info as you would probably like but...... I listened to the Sugden at my local dealer recently; it was hooked up to a pair of Audio Physic Sparks, and an Ayre CD player. I thought the the system sounded REALLY good. It was his "budget" set-up in his small room (probably about 10x12)..... I'm not sure what music you listen to, but this would definitely work for my tastes....


I can't comment on Sugden other then my LA-4 Pre, but Canor Virtus i2 is a fantastic amplifier. 40 watts class A and just beautiful sounding for that kind of music.
