Teajay, I can't speak for others but have had a Blowtorch preamp for several years (my system description is linked below) and so am very familiar with it. Compared with other units it simply gets out of the way of the music better, transporting the listener to the performance venue. Dynamics, soundstage, and imaging are outstanding. The downside is there is a good chance they will not be available any longer since Bob Crump of CTC Builders may be moving soon.
Bass performance in smaller rooms (mine is the one to which Jafox referred in his most recent post above) is trickier than in larger rooms, a significant reason being that room modes can be harder to tame and can be extremely difficult to handle with cone woofers with the energy concentrated in a relatively small area. A speaker with larger radiating area, especially a dipole, distributes energy much more evenly in the room, exciting room resonances less and making them more manageable.
