Audio Research CD7 sliding cover - How it works?

I had the same issue you are having a number of years back. You most likely need to bend the metal guide on the underside of the sliding cover so it fits into the plastic guide which is located on the inside left top once you open up the slider.

Gregf1, thanks a lot for your post.

Actually, I was able to figure it out last night myself. Now it slides very smoothly. CD7 is such a nicely designed and built player. Very solid and heavy-duty.

I was looking at the Marantz SA7-S1 but changed my heart for the ARC CD7. Well, the SA7-S1 is a good player but the CD7 is much more involving and emotional, thanks to the use of 6 tubes (mine was upgraded by ARC to have the 5881 tube, which replaced two 6H30 tubes).

CD7 presents a bigger and deeper soundstage, more air, more layers and better separations. These are my initial impressions after a very short audition.

BTW, I wonder if there's a dimming functing for the LCD display on the CD7. I read it some where either CD8 or CD7 has this feature (4 step dimming). But it doesn't show in the instruction manual.

Thanks again, everyone.

Congrats on the CD7 - I don't own one, but just heard one last week and it was the sweetest sounding CD player I've ever heard. I've not listened to anything super expensive, so maybe there's much better, but to my virgin ears the CD7 was wonderful.
