I concur using better isolation below Transparent networks make a quite dramatic impact. Lower noise floor, better tone color, crystal clear highs and better bass articulation (not stronger but clearer bass tones with much less artifacts). I first tried wooden blocks to keep the networks at a bit higher to floor, the net impact was arguably better but with reservations. Then decided to put Acapella bases (were spare at the time) this time much better with no ifs no buts. Unfortunately used to order a pair of SRA for the networks before trying Acapella, hope they raise the bar or are at least at par with Acapella. I will update this thread after SRA getting delivered.
I just found time to update this. The impact of SRA bases is hard to believe. I have thought previously they would only make a subtle difference compared to Acapella bases, I was very wrong and SRA one more time has succeeded to surprise me. I have never thought Ref MM2 would be that good. With SRA under networks and Shunyata DF-SS elevetors, I bet my Ref MM2 may beat Opus MM2 without any cable elevetor plus network base in some areas. So, treatment of network with best possible effort is essential to get maximum of Transparent. Ok, if I need to mention a few sonic improvements, the most vital one is clarity, lack of noise, especially high frequencies are crystal clear, those improve transparency and resolution. Fatigue is completely gone, even the most complex musical passages are delivered w/o any stress or harshness. Bass texture is better and lower frequencies are stronger, helping to a more realistic and 3D presentation.
