Check out VTV for reasonably priced Class D Hypex nCore NC1200 amps. 400/700/1200 into 8/4/2 ohms. I am happily driving my 1.7s (in a small room) with the Purifi amp (400w onto 4 ohms). The Purifi is the "evolution" of the designers work who developed the nCore amps (Bruno Putzeys).
VTV had some production issues early on which you will likely come across in researching them. These issues seem to have been resolved. The do offer a 30 day return policy. They ship free to you, so only financial risk is paying return shipping.

Can you describe a bit more about your Purifi/1.7 pairing ? I have had my eye on the Purifi amps for a while.
I am busy tonight/tomorrow, I will get back to you either tomorrow night or Tuesday.
Thank you...I am trying to open my mind to class D-physically I have no other choice, cannot lug the pair of 85lb. monsters'
The Cary preamp might mate well. With the caveat that my room is 28'x16'x10'
Is the realization of volume comparable to A/B traditional with comparable power ratings and high current. My old Yamaha M2 was not high current enough to drive the 1.7. Thanks Kurtle!
I read of lots of folks choosing tube preamps to pair with class D amps, I have no experience here. AA inmate Feanor has posted about this, using a couple of different tube pre's with his Purifi.
In a room the size of yours I would believe the NC1200 would be a much better choice than thr Puifi, particularly for Maggie's. The NC1200 is rated at 40 amps current.
The Purify in my small almost square room (12x14) has plenty of power. The input gain is at 19 (can be set to 26) and I normally listen with the volume control at about 9 o-clock, never higher than 12 o-clock.
I really think you would be better served by the NC1200 in a bigger room though.
PS Audio has some nice (albeit more spendy) options available using the IcePower modules, as does Wyred4Sound.
As for A/B amps, check out the link to the new Audio by Van Alstein A/B 300watts into 4 ohm amps that weigh in at 17 lbs a piece (that's class D territory in terms of weight). Frank Van Alstein makes very nice stuff. These run $1699 each.
Sorry. Here is the link to the Audio by Van Alstine M225 amps, apparently I forgot to paste it in the earlier email mentioning them.
