Scansonic mb serie

I think I am a little bit over 100 hrs since I lost track of time. Per Xti16's suggestion, I plugged some foam (not a lot so the air can still flow) to the bottom port. The bass sounds cleaner and tighter. I invited a few friends over this weekend to listen to my system. They all thought the system is balanced and lively. We tried different USB, interconnect and speaker cables. The system revealed the characteristics of those cables precisely. I had a rocky start but I'm having a lot of fun now. BTW, I also tried USB Regen brought by my friend. That little thing worked beautifully. I'm going to buy one for myself.

Jjue - Glad everything is just starting to come together. Yes I would try to track the hours. I would suggest your next step would be to replace the foam with paper (like paper towels or toilet paper [clean of course LOL]) after 250 hrs. That way you would slowly opening the ports. Unless your room is extremely lively you shouldn't to plug the ports. Are the speakers on carpeting or a hard floor like wood or tile? Padded carpet sounds a lot different than a hard floor even from just the decoupling feet. When I had the D1's granite slabs under the feet added a lot to the mids and sounded a lot better to me. But with the D2's the mids are there without granite slabs. Bass was a bit tighter too

Xti16 - Thanks again for the advice. I'll keep track the hours and try paper once it's over 250 hrs. My speakers are sitting on carpet now. I'll try adding concrete/granite slab under them and see what difference that makes.This is a lot of fun :)

Adding the Granite slabs will make them a little more forward sounding. If your speakers are on a hard surface the granite does very little except raise them by the thickness of the granite. I liked the granite when I had the D1's but not so much with the D2's (note when I added the granite to the D2's they were not broken in yet).

Jjue,
Our cases are similar, difference is the electronics.
the MB2.5 crossed 120hrs, and the bass considerably improved, which helped other frequencies to emerge and it is listenable now, out of box the sound was nightmare.
I was even planning to return the speakers to dealer and get whatever refund the store can offer, however the good people in the forums helped me to stick to the speaker and will wait till the burn-in is complete(500hrs), however the from this point we can expect only good sound to come.
