My first separates system was all Boothroyd Stuart Meridian - with the 101 preamp and the 103D power amp with the twin power supplies - so, solid state. After a family financial set-back, it was almost 10 years later before I could afford another separate system - a pre-owned Audible Illusions Modulus 1B and Rotel RB-870 - tube pre and SS power. The Modulus 1B never sounded "right" until I ripped all the guts out of case, and screwed everything onto a wooden butcher's block. Next, it was a BAT VK-3i (tubes), replaced by an FM Acoustics 266 (SS).
When I started Genesis, I "downgraded" to the FM Acoustics 255 - because the 266 did not have single-ended inputs. Now, I have four preamps in constant use - the FM255, the Melody SHW-1688 (tubes), the Arcam GFP-750, and a prototype Steve McCormack/Gary Koh preamp that has been in the works for the past 16 months.
