Where is my weakest link?

Just moved back to my newly remodeled home, finally got to hear my system again. My system consists of:

Sony SCD-777ES
Sonic Frontiers Line 3SE (Siemen 6922)
BAT VK-150 (stock Sovtek 6SN7)
Sonus Faber Amati Homage
AQ Diamond X3
AQ Clear X3
Cardas Golden Cross power cords

My room is 14x18 with speakers on the short wall, about 5' from the back all. I have very LITTLE bass. I have moved the speakers to 4' from the back wall to experiment, but no big improvement. I lost more bass when I pulled them further out of the back wall as expected because of 1/3 node cancellation.

I know Cu interconnect will give me more bass. Short of changing all my cables, what else can I change to improve bass without losing the transparency? I know Siemen is known to be on the lean side, should I start there or the 6SN7? Thanks for the help.

How was the bass before you moved and what where the room dimensions?

No dedicated AC lines? Or power AC conditioning maybe the biggest bang for the buck. What are you using to isolate vibration with the CDP, etc.?

Your cables aren't up to par with the rest of your system in my opinion. I've owned the cables you have as well as the 150SEs and personally I would think you are missing out on quite a bit with the Audioquest cables

Take a spl meter and test cd and get some readings before you spend a bunch of money, place the speakers for best bass responce and tweak from there. Marakanetz may have your answer if that does not work.

To answer some of your questions, the room they used to be in was slightly larger (19x14). I got more bass driving them with PS Audio HCA-2 or Pass X-350, but tube is ultimately what I wanted and settled for. Listening position was also tried, but at 3' from the wall, it had worked well for me for the past several years.

Yes, two dedicated AC lines with power filter feeding CD and pre, power amps are plugged straight to the wall. No bi-wire capability with Sonus Faber, so one pair of amp is all I can use (thank God).

Sounds like wire is what I should replace? I had very good luck with JPS Superconductor 2, but they were so stiff they broke one of my input on the SF Line 3 SE. What else is out there that won't sacrifice the air/speed/transparency of Diamond X3 and still give me more bass?

Thanks.
