The Pre90 is not released yet. A90 doesn't have remote.
Firstly I want to thank Topping for the D90 DAC. It's fantastic and beats everything I compared it to till this time (even some very expensive DACs, even the little D50s in direct comparison beated a Hegel $4000 DAC!)
Secondly, the Pre90 really interests me, I wanted to buy A90 and use it as preamp to drive my Hypex NC500 monoblocks. My latest setup consists from D90->Monoprice THX 789->2x Hypex NC500->Thiel CS 2.4.
Now the questions, I use the NC500s with bypassed input buffer, so I need lot of gain. I use Monoprice headphone balanced out to drive them.
Will be the Pre90 based on same circuit topology as the A90? Will it be in the same price range as D90/A90? And same case design?
I was ready to buy A90, but the remote control in Pre90 is more important to me, than headphone output.
Thank you and I wish you lot of bussines and personal success.
