Have you considered an Audio Horizons preamp? Here is a link to a review of their phono stage from a prominent reviewer:
i have owned both, while the 5.5 is an exceptional pre-amp for the money with it's versility, especially with the built in phono section, the Lamm is in another league, sonically.
If performance is your goal, the Lamm sounds more like music, mates well with the LP 2 phono pre-amp and delivers you to another level of naturalness.
Please understand the 5.5 is an excellent pre amp especially with NOS tubes,
and with the remote and phono built in it is a great value, without going overboard.
I agree with Logenn about the sonic qualities from Lamm. I think, nothing comes close. They have not these mechanical artifacts you will discover so often, no grain/coloration.
I bought a used LL2 some ago with NOS Tubes and after a few days I sold my Aestheix IO sign. This is one of the rare outstanding designs, very reliable and easy to go with amps. One of the ultra bargains of today for a Listener.
