Well, I got the Lumin T2 home yesterday and set it up to play directly into my two amps. I have the Sbooster standing by ready to be installed. I decided to give the T2 a run on it's own first. I experienced a much better soundstage and separation between the instruments and the vocals. At first the bass was missing. That smash that I love. So, I hooked it up through my preamp and the low end and the smash returned. My speakers have two 12" woofers and plenty of power, so that wasn't the problem. But with the preamp in line there was a slight veil that wasn't there when going direct.
I then removed the preamp and went back to running the T2 back into the amps. Over the course of the long evening, the music got sweeter. I am now at about 20 hours of continuous play and the base and the fullness are appearing. I am going to add the Sbooster and run it in. I am starting to become highly optimistic that running direct is the way to go.
My wife and I went to two local audio stores for reference. We demo'd two different sets of Magnpan 3.7's with subs and for fun a high end setup in the 250k range. I came home and wasn't embarrassed. For the amount of beer money I have spent, I think I, with just a couple of more tweaks, will decide to be very satisfied.
Conclusion. I am going to Sboost it and let it break in and continue to run the Lumin T2 directly into my amps and control volume with the Leedhs volume control.
I am curious if anyone has tried different fuses with the Lumin T2?
