Phono Preamp. With transformer or fully active

What is the difference in sound between a fully active phono stage and one that uses a transformer for part of gain 

I read  discussions in External SUT’s being used and phono stages with built in transformers ?

I noticed that CJ Tea2 has two inputs one is with transformer & one is fully active ?

l also read discussions on fully active 
What is better?   Lol

is the sound softer, more detail , more soundstaging? Quieter?

I used a Lundahl amorphous core silver transformer and liked it very much. As Mulveling said, they are not as warm as some others - but the clarity! Then I built my own phono/pre, and built a lot of gain into it, so now run my Koetsu platinum direct.

Differences are just an added touch of clarity, added touch of warmth, and added touch of dynamics. So I use the MM input and run the volume at 3 o'clock. Still black silent as a tomb, so there's no down side. But I suspect that if I was using a FET input stage instead of aerospace bipolar (or vintage 6922's), the Lundahl would be notably better.

I completely agree with Raul with one important exception: "(the first posts in the thread are wrong ...)". I think that Raul has misunderstood them.

Also consider Sowter transformers. They aren't up with the big Lundahls, but they cost a tenth as much, and if you aren't using a $5k cartridge, may be preferable. OP should know that Mulveling is a connoisseur of the highest end cartridges.
