That’s great and thanks for your response. I had a very busy weekend.
I wish you good luck on Finding those Sansui integrated amplifiers. Any of them that I’ve listed will do, and you will be in for a world of listening joy that even headphone amplifiers at 2 grand can’t compete with. A resistor pad is used to step down the voltage, but it was designed at time where if you needed more juice; you could crank it up. And the best part? The speaker terminals and headphone out are derived from the same high quality signal path.
It's not necessarily warm, but slightly smoothed over, yet detailed, wide and inviting overall. That's how I'd describe them.
