I can't comment on the exact pieces of equipment you mention, but I thought it might be of interest to discuss my experience in upgrading from a BAT VK-3i to a Sonic Frontiers Line 3.
The Line 3 was a pretty significant upgrade, as it should be considering the difference in price. The Line 3 is much better at the frequency extremes -- and capable of much better resolution. It is quite a bit more neutral that the VK-3i. The Line 3 is also a LOT more dynamic.
I agree with Bryhifi that the VK-3i is a very musical preamp. It gives just a touch of warmth to the music when outfitted with NOS tubes. It is also very forgiving as well.
If find the Line 3 to be even more musical. The problem that some may have with it is not very forgiving and will certainly expose any warts. It is going to pretty much pass on the signal sent to it. Depending on the source, this may not always be a good thing.
