I have about 70 hours on the silver 10s so I'm past the recommended break in period.
Music-wise I've been trying to identify songs with good, clean, bass guitar to check out the low end without sound effects or synthesized sounds. The ports remain unplugged.
I am not a musician so I can't really identify notes or anything, I just go by what sounds good and clear :) "normal listening" is at 52db. this is acceptable to my wife and kids. Most of my critical listening was with a bit more power. In the 40db to 46db range.
My pre/pro is set up to automatically select the front speakers to full range for 2-channel audio and to small for 5.1 with the appropriate input.
Listening to the TV thru my amp one day I heard a commercial with nice plucky bass guitar. I had to check to verify that my sub was not on. Nice deep un-boomy bass.
Sarah McLachlan's Back Door Man is a very good tune for bass with some percussion added in. The 10's do an outstanding job in the bass delivery, both in clarity and strength. I discovered this tune this morning and the delivery across the board in my room with my system sounds soooo good! In fact, it will be my go-to song to show off the speakers. My Bose headphones (free from work!) cannot come close to the accuracy of the 10s.
U2: Love is Blindness church organ. hard to rate the speakers here because the organ notes are fuzzy regardless of what I listen to them through. You can hear them and feel the floor shake. If any of you know if they sound the way organ notes do then please let me know. Regardless, the speakers make thing shake even at low volumes.
Stevie Ray Vaughn Sky is Crying SACD also contains some good bass tracks. Sounds wonderful. I also have Brothers in Arms and DSOTM on SACD. The speakers do a great job alt all frequencies and each individual instrument and voice are clearly separated. They're both 5.1 and sound terrific. The MA 10's integrate nicely with my other speakers and sub.
Mixing in synthesized sounds: Black Eyed Peas Boom Boom Pow. Wow....fills the room, shakes the house, makes my wife mad. I like it. Same with Depeche Mode's Personal Jusus Pump Mix.....whole lot of sounds going on with a nice pumping beat. Even my 9year old son likes listening to this.
I downloaded a 35hz-39hz tone test. I need a spl meter to get official results but the tones were all clear and at what appeared to be the same level. I may try the 30-35hz test next.
I have some sheffield labs music, including their track record drum record. the drum solos come across with nice depth and width. Similarly, Manheim Steamroller's live Chrismas CD has a soundstage that I've never heard before. In my listening room the on-stage flame bursts sound like they're over my right shoulder. I listened to this 3 times to make sure I wasn't imagining things.
Overall, these speakers are a very nice step up from my old B&W DM630s. Much better low end response, much better sound stage and do a fantastic job with complex music in my existing set up. They like power and breathing room and sound incredible with high quality recordings. I'd like to hear from others that have taken these home and ahve run their favorite tracks through them.
