There is a big improvement, especially in the area of the mid bass bloat. It is also a bit quieter, but still is a bit noisier than the BAT VK-50SE. Same huge soundstage with tonal improvements. The 6h30 tube is a real nice improvement. If you have to stay with ARC, I would highly recommend the Ref 2 MK II.
Other fine preamps to consider are the Aesthetix Callisto, BAT VK-50SE and if you want solid state, I have a friend singing the praises of the CTC Blowtorch.
Good luck.
