<font color='#000000'>I currently have a pair of Axiom M2i speakers, Pioneer SACD player, Yamaha HTR-5550 receiver, and Velodyne VX-10 sub. I eventually plan on upgrading the sub to an HSU STF-2 or VTF-2. I'd also like to swap out my receiver for a preamp or integrated amp, as I won't be doing anything but stereo listening, however I don't really understand the differences between the two. Several people have recomended NAD for the amp, would this be a good way to go, and what models specifically?
Also on the sub, is the STF-2 or VTF-2 the better way to go?
Thanks,
