John Atkinson ran some tests on this point a while ago and concluded he like the sound better with a pre in the system. I used a VK-300SE for many years and will say it "just makes beautiful music". Adding the VK-225SE now-or-later gives considerably more "gusto" as doubling the available power should. I'm a hard-core BAT fan as I love their pure, simple, natural sound (no fancy-schmancy -just pure music). Take it or leave it, just my advice.
ISO Advise on choosing Ayre or Bat power amp
Looking at an Ayre V-5xe or a BAT VK-225se-both used, approx. same age and WPC power. Matching to Aerial Acoustics LR-5’s ( 4 ohms, 89 sensitivity) listening room is 22x24.
