Sound is too thin. What to upgrade, add or remove?

Very nice set up !. I love the Supratek Pre -
.
You have a lot of great suggestions so far – here are mine
.
Get your wife to listen to the changes as the sound improves – let her hear the before and after. It was surprising to see how much more interested my wife became after getting involved in the process - she also became more open to changes I wanted to make.
.
Continue to work with the speaker placement and some low cost room treatments first.
.
Definitely get the main components separated and on their own platforms. Zoethecus make a great piece for their stands called a “Z-slab”. You can find them used on Audiogon for around $ 100.00 - $ 125.00. They should make huge difference when put under your CD player and Supratek. Get one and move it around under different components and see what results you get. If you are not happy, you can easily re-sell the Z-slab and get all of you money back out.
.
Put Symposium Rollerblocks (or other coupling devices, but Rollerblocks are far and away my favorite) between the platform and the component. This will be another significant improvement.
.
Power Cord - BMI Sharks can be picked up on Audiogon for $ 200.00 - $ 250.00 (there is a 5 footer up for sale right now for $ 235.00 OBO). Get one and try it first on the Amp and then on your CD player - If it gives you the results I think it will yield, you can buy more and improve the sound further. This cable can really punch up the bass and give you more detail without glare or brightness. This is a great power cord for the money. I went through 6 or more and the BMI Shark and it descendants were the best sounding by farm. Two years ago they were selling for $ 800 – 1,200.00 (new). Great Value !
.
Consider getting a used line conditioner , Hydra or BMI – IPLC and replace your outlets with Albert Porter’s Cryoed receptacles or other high quality Cryoed outlet. Dedicated lines would be great but a good bit more costly.
.
Feel free to email me directly and I can explain a bit more in detail

Jewel,

Good comments from Islandear, but I would recommend the Zoethecus Z-slab over either the Symposium Svelte shelves or the Symposium Ultra shelf.
.
I have had all three ofthose shelves plus the Rosinante Dark Shelf, Black Diamond Racing Shelf and Silent Running Audio's custom built stands.
.
The Silent Running stand was clearly in first place (but costs around ( $ 600.00 - $ 800.00 new), the Zoethecus Z-slab came in second, then Rosinante, then the Symposium Ultra, followed by the Svelte Shelves and in last place the Black Diamond Racing platform. An audiophile friend and I did some blind A/B comparisons using several types of music and the results were clear, repetitive and unanimous between us.
.
While the Symposium Roller Block system (get the Grade 2 Tungsten Carbide balls) is an amazing product ( I compared it to Walker Valid Points, Black Diamond Racing Cones and a few other similar products and the Roller Blocks are by far the best of what I have tried), their Shelves, while quite good and better than no shelf, don’t produce the same stellar results.
.
Great Power Cords, Shelves, and Coupling devices when well matched to you system, do absolute wonders for the sound -It is very much equal to a major component upgrade.
.
I am looking forward to hear how your journey progresses. Do keep us all updated with your trials and results.
