I too have an LS7. Upgraded from an Adcom GFP 565. The difference was amazing. Sound stage, bloom, no electronic haze or grain. Better bass. But if I could have afforded it at the time I would have gone for the LS-2 Slightly better. Longer decay on the music a hair sweeter and airier. But overall love the preamp Have original tubes, want to try NOS Mullard or Bugleboys. Solid State amp B&K ex 442 and B&W Matrix 802s3 speakers.
