Affordable integrated pure class A?

@iopscrl What are your other components ?  What speakers ?  How much power do you need ?

I'm starting from scratch and eyeing speakers that are not that sensitive - only 85hz. So I don't think SET will work, will it?

Assuming you meant 85db, not 85hz, you're correct that those are low efficiency speakers and will need plenty of power. It could be class A, but that would cost you a pretty penny, for sure, especially if you go tubes. If you are on a modest budget, considering easier to drive speakers will make things much easier on your amp choice. 
FWIW, I have 85db Sound Lab electrostatics and also love the sound of many class A amps. I spent over $3k on a used Krell FBP-300, which is a fraction of the cost of other tube amps that I used with the SLs previously. At 85db, you want to be pretty committed to the speakers, as I am, knowing that amp matching will always be important and relatively expensive. Cheers,

A really great sounding inexpensive integrated is a Tandberg TIA3012.  It’ll set you back $300-350 and is heavily biased into class A as it runs very warm to the touch.  I had one for a few years and loved it.  Kept it on all the time with about 4-5” of ventilation on top.  100 wpc, MOSFET outputs, very warm and tubey sounding.  I would take one anyway over NAD or many others mentioned.  Only sold it to go to separates.
