Opinions please on older Sony ES Pre-amps

For what it is worth, I had a TA-2000ES. I paid $1000 for it new, and thought of it as a $300 pre-amp coupled with a $700 digital sound processor.

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.

I owned The Sony TA-1000 ES pre amp for a few years in the late 80's . I dont recall the model having the letter DM in it ? . But my honest opinion is that it will sound horrible.
It was made when the word "digital" was just coming into public consiousness. Revolutionary for its time, but antiquated for today.
