Modwright Transporter v. Sonore Signature v. Bel C

Hey. I am looking to replace my MW TP, love the sound, not that happy with the software. I will replace it with a SOnore Rendu and a dac. I am looking at the Sonore and Bel Canto dacs. I wpould appreciate anyone's thoughts and experiences with thse dacs. BTW, I have a tube pre and thus and not sure whether I need a tube dac (love tube sound).

Thanks.
