Charles, your last comment is exactly what I was thinking. Many of us who have had the pleasure of sampling Blume's work have found it to be exceptionally true to music. Savatore would seem to be in that camp. I would tend to take Savatore's recommendations on equipment seriously, because "it seems we hear things in a similar manner." For the same reason, I take Jonathan Valin's reviews seriously. We are both Magnepan guys. We hear things the same way.
And for what it is worth, my preamp's days are not numbered. It's not going anywhere. Now, in a second system or a low budget system, I would certainly think about trying either an integrated amp or a digital volume control, since I am likely to remain a single source guy.
