CD Player into amp?

I had an early 90`s top of the line ($1500) Yamaha CD player with it`s own volumn control, I was able to run it directly into an my Classic 120`s.

BUT your CD player must have a volumn control,(this player did)otherwise your sound would be at full volumn and probably self destruct the whole system.

You are by-passing the pre-amp and extra connections,(IC`s)and the sound is a lot more revealing in every way, except that it then revealed even more, all the hash and grit and robotic sound that is CD.

AND...make sure you have VARIABLE outputs on the back of the CD player. On some CD players, the front panel volume control only controls the headphone.

There are no out controls on the CD Player but the remote has volume up and down. Is this OK?
Thanks
