How long to burn in Rotel rcd 1072?

Select a disc that offers both a high average listening level AND a wide frequency response to it i.e. lots of deep bass, lots of extended treble and a loud recording. Let this play in the machine on repeat 24/7 for as long as you can. Obviously, i'm talking about doing this outside of normal use. While the machine will continue to break in further down the road, if you don't like the machine after several days of continuous play, you probably never will.

As a side note, i've found that most units respond to this type of "break in" exercise phenomenally well. What works even better is to use a disc like the Ayre Acoustics for one week and then select a disc of music like that mentioned above for the second week. After using this approach on several different players, the difference in sonics after 2 weeks of continuous play was pretty drastic. This approach can even be used on older players with some benefit, depending on how much actual playing time they have on them.

I don't know how much time you have to test this unit before you can't return it, but the more time that it spends playing discs and not sitting idle, the better it will sound. Sean

PS... current Rotel gear tends to sound somewhat lean and bright to my ears i.e. similar to solid state Musical Fidelity gear but not as smooth or refined.

If you bought from a dealer, you may want to take it back and question them. I just recently picked up the same player and am so happy I can't believe it. I was sceptical of a Rotel player, and heard nothing but good about this one. The night I plugged it in, I knew it was staying for sure. It's weird that we had such different opinions.

I experimented a bit last night and found that the dealer had plugged the Rotel into an extension cord. I read the directions and it advised against doing this. I plugged the Rotel directly into the wall and it was much better. I still think it is a bit edgy but will listen again this morning after leaving it on all night.
