Opinions please on older Sony ES Pre-amps

I tested one of the expensive Sony Preamps from the ES series recently (the preamp was dating back to late 80's. I personally did not like the sound of the preamp as it had sort of coloured the sound and not to my liking. It was surely built like a tank and was very heavy. If you can try it in your own system see if you can relate to it and it gives you the sound it should rather than alter it.

Jonsonneborn,

Are you a Patricia Barber fan? Reading between the lines I could sense from your post (second last line, a little rich for my blood). If so don't even think of retaining the Sony!
