I haven't heard the LS26, but have a REF3 and have directly compared the REF 3 with a REF 5 and I can tell you they are very close. So close it wasn't worth it to purchase a REF 5. Even my dealer said the same to me. The REF 5SE on the other hand is an entirely different story. That is definitely better than the REF 3. But, I can tell you that the REF 3 is an excellent pre-amp still. if you are thinking about an LS26 or a REF 3, take them both home and demo them in your system. Don't change anything else, just the pre-amp and play it with your favorite music. Make sure the tubes still have appreciable life in them and are not on the ragged edge of failing before the demonstration.
