Very familiar with the JD9 and an assortment of other sub-$1K units. The JD9 is not really a pure tube phono preamp. You can really tweak the JD9. Some good NOS tubes, upgraded fuse and AC cord make a BIG difference. You can also change out resistors (little to no change in my unit), add some sorbothane, remove the tube protectors, upgrade the feet, etc., etc. I have tweaked mine pretty extensively and I can't seem to find anything better unless you start looking at some things that go for $2K or more. Obviously, I can only sample what I can find in the local shops in the SF East Bay area, so I have not demoed more than 5 or 6 units. But I am a big fan of the JD9 for the money and with some upgrades.
