considering buying some bluray storage racks from canam, but they are metal. It seems to me this would have a negative effect in the room for sound. Is this true. What about Glass shelves?

Depending on the design of the racks they might add some acoustical diffusion which is usually a good thing.

It depends on what you are trying to "do" with your system.

If you are trying to have it accurately reproduce sound-then you should be in a room that is free of reflections (including walls-ceiling-large objects etc.) if you want ot hear the music as it was recorded.

However if you are wanting a particular "experience" that is not in the music-then it could be anything-fro pointing speakers at walls to make the sound "bounce around" or whatever. But it is not faithful to the original recording at that point.

I would hope that the equipment shelves would be out of the main pattern of the speakers enough that it would cause minimal effect.

But if you already have the rest of your room done properly (ie in the first reflection path), then yes any hard surface will cause reflections.

The extent depends on the location-pattern control of your speakers and so forth.

Some people like the sound to bounce around (Bose made a fortune on that one) and others like accurate sound reproduction. You can't have both-with the same system.

Where you put the shelves is far more important than what they're made of. Obviously you don't want shelves that rattle and buzz when bassy music plays loudly. But that's a function of how well they're built. The more important point is to put shelves along the side walls behind where you listen, or at least out of the way of direct reflections because that's where absorber panels should go.

It would be under the screen, not in any direct path of any speakers and this model:

I don't have any acoustical treatments in the room other than carpet and furniture. I may plan to add some down the road but my room is a smaller room so it might be tricky at 10'9" x 16'5".

I was planning on covering the top of the drawer with black velvet to reduce reflections from the screen.

The smaller the room, the more you'll benefit from bass traps and other treatment. You don't need a lot to make a big improvement! And velvet will hardly do anything useful. This short article is mainly about home recording, but all the same principles apply to hi-fi and home theater too:
