Aldavis, no offence taken! I use the term "bloom" because it is commonly used for the added warmth from tube stages. I am not the guy who looks for really creamy, flabby and tubey sound. The 6H30 tube I use in my designs is also known as "the solid state tube". Not many are using it because it does not add the usual "bloom" and soft tubey sound signature as many other tubes do. I would hate to mask existing problems with tube stage that rolls off the highs and "blooms" so you don't hear the harshness. I take a different approach of having everything as right as possible before the tube stage. Then, the transformer coupled 6H30 adds just more naturalness and musicality to the sound. Why is that? It is becuase the 6H30 is Super-linear tube which does not have much gain. This allows for design without negative feedback. The end result is dynamic, transparent, 3D solid-state-like sound with added high frequency sweetnes and liquid midrange coming from the tube. Since all passive or active components add noise and distortions, my tube stage isn't free from that - it adds them too. The question is if you would like to make things worse using preamp.
