Cable / Upgrade Recommendation


I am consider upgrading to new cables for my 2-channel system(Adcom GCD 750 / Morrison ELAD / Audiosource Amp2 bridged / NHT VT1.2 / MIT T2 cables), and I am not sure which cables to try. The system sounds a bit bright, so perhaps cables with warmer characteristics? I understand that the T2 are already on the warm side; maybe I should consider upgrading something else? FYI, I listen to mostly jazz and classical.

Thanks in advance for any advice!

Sorry about forgetting to mention this before...I am also using Bi-Wire version of T2 (8 ft.) between the NHTs and the Audiosources.
I have been playing with many things listed here. I have an EMC-1 CD player and was playing it on a glass stand. I big NO NO. I hated it, SO I took off the EMC-1 feet and used some #4 cones under it, much better. Also I switched out a Mamba Silver conductor power and upgraded to a Black Mamba on my Pre Amp, another nice improvement. The last thing I did was started switching cables. I liked the AQ cables because but they were abit forward, yet the Tara cables were to layed back, SO I switched to XLO and got the best of both worlds. Just play and have fun. But be careful don't go broke.
Raise the power cond. off the floor? Hey I'm gonna try that! I have a Chang Lightspeed 3200 & a 9900 Amp; they even came with spikes but I never used them - doh! Thanks!
Glass shelves - No No is right!
Now here's a few more basic tweaks for harshness that I thought of... (1)Basic contact cleaning: signal cables, spkr. cables, AC cables, AC receptacles (de-energize first!) clean everything with pipe cleaners dipped in Kontact (best) or even denatured alcohol is better than nothing at all. (2) Burnish all AC cord plugs with crocus cloth (best) or even an eraser - follow by contact cleaning. (3)Install a better AC receptacle in that apartment's wall. Try to pick up a Hubbel or at least a 20A Leviton industrial grade receptacle. Sure $15 or $20 is a pricey outlet, but is a really cheap upgrade considering the sonic enhancement.
Hey, the RCA cable that came with the Morrisson ELAD is as good if not better than any cable available, it's RLC parameters are precisely what is reguired for audio signal transmission. I have used the Elad and the suppied cable as reference components for about a year now and believe both are amoung the very very best in transparency and value. IMHO, forget "warmer" and look for the more likely sources of "brightness". Are you convinced it is system brightness vs bright recordings and a resolute system. I bet your system sounds fantastic! Look at getting $100 worth of auralex wall treatment-it works and it looks cool- and a dozen new cd's and time to listen....then if later you must spend look at new speakers ...Morrison's new speakers should be available soon...if the speakers are like the ELAD then life doesn't get much better!!!
MGS, I am using Transparent Ultra between Sony 9000es/dvd/cd/sacd and ARC ls-15, Balanced Ultra to Proceed HPA2 and Super-biwire to ML Aerius i. I started off several years back with "music wave+" line and was fortunate enough to have a salesman and dealer that gave me a good deal to trade up into the premium line. Once there Transparents' trade up program took over. I hope to upgrade the speaker cables next. I never could have afforded to start at this level.
