I still don’t know what SN3 sounds like, certainly, but I don’t find the SN2 missing anything in the bass region, at least with the K6; and I have other well-tuned systems as a counterpoint. That said with almost over 500 hours of operation already, so I think it can still settle something, but I don’t think much more.
At first, in the first few weeks, 50h.-100h. running, I even opened a thread, quite worried because I found it to sound pulling bright and, yes, with the bass a little loose, and thinking I could have made a wrong decision buying it and I was going to need more reinforcement; but, as I point out, none of that now, after the tuning and settlement of the system, only a really terrific integrated very capable to filling the 144 cubic meters of the room with balanced and coherent sound, in all honesty too…
