Hi Tboooe, the signature rack has a weight limit of 25kg. If you have heavy components you cannot use it. I am 100% agreed with Jfrech. I have E12 with Harmonix RF-999MT under the spikes(I have tried spikes going thru carpet, with Harmonix is better. I have also tried Isoclean TT-009, still better than spikes going thru carpet). HD09 with Cerabase for power amp. I used them on carpet. I have not do comparison with Cerabase and Rollerblocks. I have Ultra with double sets rollerblocks on the top shelf for CD transport. They really improve the sound compare to the E12 alone. I find similiar result as Jfrech. With Rollerblocks alone, better highs but some of the bass is gone. With Ultra, it will add some bass. Background more quiet and better imagining. I have tried putting the Ultra on top of HD09, it doesn't sound as good as HD09 by itself. I put Aurios MIB between HD09 and power amp. The sound became smoother and more alive. I have ordered a set of Cerapuc planning to replace MIB. It will arrive next week. I will do a comparison with Cerapuc and Rollerblocks on transport.
Currently I have 4 sets of Rollerblocks, 2 Ultra, 2 Super and Svelte. I really like Symposium products. And I feel that Finite Elemente products are better(cost more as well). I have used Solidsteel 5.5 before. No comparison to E12.
I have put 2 bags of lead shots(about 5kg each) underneath the rack on the carpet(not touching the rack). The sound became smoother.
If you want to see my system(mid price equipment, probably you may not be interest) I can email picture to you.
