I am using a Laufer Teknik MP64-16 Memory Player. It is a server/transport with SSD with CD ripper. It can connect to the DAC via XLR/SPDIF or ethernet (to network switch or renderer). It comes with JRiver music software which is a bit clunky but I control it with my iPad instead using MConnect HD app. Sound quality wise is as good as or above the Innuous. You can get used ones under $10k.
