Vladimir Lamm took me through his new 3 box LP 1 Signature phono preamplifier. Each channel has its own power supply. The all-tube design uses transformers for the first MC stage. There are three inputs: two MC, one MM. The two MC inputs have different turns ratios to accommodate both ultra-low and medium low output MC cartridges. Price is (gulp!) $37,790. You can be sure the highest quality components are used throughout. It was ultra-quiet and sounded superb playing back a track from "Mel Torme Live at Marty's".
When I asked Mr. Lamm if the signature referred to the fact that to own one you have to sign your life away, he did not laugh. Actually I did not make that joke with him. Just you.
