What sort of late night hours and dB levels are you talking about. Are there neighbors above, below and/or next to your listening room? Talk to your neighbors about what you're doing, even invite them over for a listen. It actually might be better for everyone if you did some sound transmission inhibiting reconstruction to your listening room. Different equipment might not be the optimal solution.
What should I do
I have an Esoteric player ,Gamut C2R pre Amp am Gamut D200 Amp and Harbeth 30.1 speakers (crazy about) I now live in condo so late night listening gone.
