Serge,
That's a great looking Yamaha!
I've done similar mods and repairs to my CR-1020. I have plugged in a Moon Mind 180 streamer, a Yulong DAC, a Denon DVD-2910 CD/SACD player and a pair of Vienna Acoustic Bach speakers. System protection is provided by a Panamax power center.
The mix of "Old" and "New" works very nicely.
