Can a Classe SSP replace a dedicated stereo pre?

Hi everyone! I appreciate the opinions and knowledge on this forum and I've been reading a while. 

I am looking to move laterally from a 2-channel setup to a basic 5.1 surround setup, as my listening does involve TV and movies. Most of my sources are digital.

My current setup involves a sabaj d5 DAC, a Modwright SWL 9.0se preamp, Odyssey Khartago extreme monoblocks, and some excellent DIY 3-way speakers.

I couldn't be happier with this for two channel listening. 

In my research for multichannel pres/avrs, I heard most people saying that the only ones that sound really good for stereo are ones made by Classe, Krell and Bryston within my budget. I'm really hoping to simplify my setup and not have to use ht bypass, switch between two preamps etc.

I've made an offer for a Classe SSP sigma. Do you think this could potentially replace my Modwright without losing much SQ?

Thank you!
