Very nice Denon CD player, but a lousy photographer!!!
Photographs taken in the early morning light, reflections galore and the bright sunlight upset the camera a bit but I hope those interested can see the basic info I am trying to show
On the front panel there are reflections all over the place, in reality the front panel has no marks at all!!!

TESTING:
This is another of our long term “consumer level” CD players from our old “green room” in our previous audio post production days. This CD player was used primarily so that a client could listen to music of their choice while they were waiting for our staff to complete a task (music production “while you wait!” well sometimes anyway)
This equipment ALWAYS was well maintained and even though quite dated equipment, it never let us down. So on with the testing …
Powers up fine
Laser head searches the media for the TOC and after displaying the total tracks found, waits for “further instructions” from the user.
I have been using this CD player continuously since I took it out of my storage units (around 18 hours daily for 3 weeks – yes I don’t get much sleep!), initially I had the occasional tracking problem (glitch) but after a complete re-lube of the head transport guides/rail, everything settled down and no further issues.
Laser head seems to be fine, no issues reading discs at all. If ever the laser head gets to EOL and needs changing (and they ALL do eventually) this uses a commonly available SONY KSS-213C head and they are currently not expensive.
Track movement forwards and backwards is undertaken by a front panel knob (move left or right) – we liked this method very much.
A nice touch is the pitch control, just hit the pitch button and then you can increase or decrease the pitch in 0.1% steps up to 12% – the change is indicated on the display. This is can be a very useful function or just a bit of fun!
Another useful feature is the multi-repeat options, not just a track or album but you can designate a section of music that you wish to play over and over and over …
There is also an auto space feature, activating this will add 4 seconds silence between each track (but the display will still display the correct play duration)
But wait there’s more! The display brightness can be stepped in 4 levels, from full brightness to completely off – this is very useful in a dimly lit studio when you may not want bright flashing lights while “things” are happening.
Outputs on the rear panel are the stock standard analog
