@shahram I have been listening to D7.2/L-507uxii combination every day and it is pleasure to do so. I listen for around three hours a day, so it is going to be a long journey breaking them in. Almost all of my albums, especially the quieter/sparse ones sound much better. I wish I had done it sooner!
@kren0006 It is indeed a fantastic combination. Since I upgraded the speaker and amplifier at the same time, I don’t know which component contributed more, I am happy for the results though. You may want to just upgrade the amp to Luxman and see if you still want to upgrade the speakers.
I may not know the right audiophile terms, but let me see if I can explain what I noticed:
1. I hear a lot more detail in the music even at low levels. There seem to be notes, that I didn’t notice before.
2. I can go up in volume, without any distortion and go down in volume without loosing details in bass and treble.
3. While listening to Jazz, I noticed that cymbals are, for lack of a better word, very granular.
4. Bass seems to have a lot more texture and much more extended than my previous setup.
Overall a beautiful setup and hope to keep them for a long time.
