A Rotel Michi pre from the mid 90's and an Amcron Crown STA-2. Used to use an EL34 valve amp in place of the Amcron, lovely midrange, loved it until the Amcron came along with MOAARRRRR POWAAAAR! I use 4xESL57s, they don't need 200+ wpc, obviously, but the grip you get off a hugely overpowered amp is impressive. ESLs seem to like either valves or very big SS amps, I'd heard this before and not done anything about it but just enjoyed listening to the valves until the Amcron turned up.
The valves are now in a spare system. That sounds great too, just an AE, tuner, a CD player and some midsize 80's Monitor Audios. Coloured? Maybe. All hifi is coloured, Naim especially, we choose the colour we like.
