I currently use the Alembic components (F1X and SF2) as my preamp. But I have to say that I am very intrigued by the Aguilar DB680. Maybe the number of Tubes has wowwed me, but the reviews seem rather potitive. Are there any users that can compare the two? What is the Ag sound in comparison? The Alembic is noted for it's simplicity and it is said to have a "by default" mid scoop. I can somewhat agree with that, although I don't have any problem gettting mids because of my bass (A Smith 6 with a mid control) and the SF2 in Band Pass give me all I could possibly want. So, hit me up with your opinions and rants. Thanks!!
