Upgrading Sonic Frontiers Line 3SE to ???


Have owned the unit a few years now, think it's time to upgrade to something better. I am happy with the midrange, top end, soundstage, transparency and all are important to me. One area I think I can use more is bass weight and dynamic, but don't want to lose any of the strength. Also like to have both SE & XLR input/output.

Have considered the following:

BAT VK-51SE
Aesthetix Calypso
ARC Ref 2 Mk II
???

Rest of my system is in flux, but what will stay is BAT VK-75SE, SF Amati Homage, VPI SSM Signature w/ Shelter 901.

I might add a solid state amp like Pass XA or X.5 series and still keep the tube amp, might upgrade my SF Phono 1SE to something else as well if I change my pre.

Reb1208,

Which sockets are the buffers in the SF Line 3? These are different than the front two gain tubes, right?
