New to this. How do I stack my stuff?


I'm new to hifi. I've asked a lot of questions here and some of you may already know my situation but I got the following by chance and for free: Audio Research LS16 tube pre-amp, Arcam CD92 cd player, Madrigal Proceed HPA2 amp. 

It is all up and running and I'm loving it. Now just trying to maximize the little things that I can. For instance, speakers had spike stands but spikes were missing so I made a set.

Now I read in the CD manual that it recommends sorbothane feet and says sound quality will be better.

I'm now figuring out that placement of components is important and that proper stands, expensive ones, are best. Well, expensive stands are not going to happen. But I can try to make accommodations that are cheap and won't turn the room upside down.

Here is how it is all situated now...let the ridicule flow, but keep in mind that I am space limited to a serious extent. Was not sure I'd get the system in my house at all:

The (very) heavy Proceed amp is sitting on a carpeted floor on strips of wood which raise the bottom of it well above the carpet. It is higher above the carpet than it would be above a hard surface just on its own feet.

The CD player is sitting on a small, simple, wooden, antique side table. It is sturdy. The pre-amp is on top of the CD player. I have no idea what this might mean in terms of SQ but the CD player actually puts out a fair amount to heat which rises up into the pre-amp of course. That concerns me.

So other than getting some sorbothane feet for the CD player, what else would be a priority here?

Finally are there issues with which cables contact which cables, how much speaker cables are looped, etc. (Most of the cabling is Transparent Super Bi-wire.)

Thanks for any assistance.

shadowcat, sorry to hear about your wife. We've been married 30 years. We lost my mother-in-law 3 years ago and my dad this month and have seen how hard it is for each of their spouses to deal with that loss.
N80. Keep your Transparent RCA cable. It’s perfectly fine. You can easily set up the CD player away from the ARC preamp using the usable length of your RCA cable. I am only referring to swapping in a longer run of the balanced IC between your preamp and power amp. Keeping your power amp near the speakers is also fine. 
“In other words which is better: higher end cables with poor component position or good component position with lesser cables?”

It is the entire system quality that needs to be considered. Eliminating certain distortions like proximal effects of speaker radiation patterns on sources and low-level, noise-sensitive preamps by using a longer run of interconnects can easily trump maintaining those distortions by using a short run of very high quality interconnects. But everything is adjudged by experimentation to discern which sounds better overall. 

Ease of use of your source player and preamp switching/volume functions close by to the seating position of you and your spouse is of secondary importance, but can have an impact on long-term enjoyment of the setup. 
shadowcat, another question. I hear people talking about room treatments and acoustic panels etc. Is the goal to get the room acoustically inert, maybe wrong term, but to minimize any 'echo'?

The whole back wall, behind my listening chair, is fairly heavy curtains. 30 percent of the wall to my left is curtains. The entire floor is carpeted. The wall to my left is rough brick with a window with no curtains and two doors. So there are two large expanses of brick. Would it be beneficial to hang something like Persian style rugs over those expanses of brick?
Believe it or not, this set of speakers is often showcased together with a turntable, exactly as presented in this YouTube video.

Not exactly optimal. Lol
