I don't doubt they're amazing speakers, I was amazed by them just out of the box; I'm just not sure if they're the right speakers for my ears and (a big part of) my record collection. I'd love a more detailed and "refined" sound than that of my Boston A25s, but I also need warm/non-fatiguing/forgiving-with-cheap-recordings speakers too.
..My setup is: Marantz PM6006 amp, Schiit Modi 2 DAC, Audioquest Big Sur signal cable.
New speakers from a new amp?Although the D 3045’s new feature set is significant, for me the biggest benefit is the power output from the D 3045’s class-D power-amp section. The change from 30Wpc to 60Wpc shouldn’t have amounted to a hill of beans -- no surprise to those who know that every doubling of power results in a volume increase of only 3dB from the speakers. That difference in SPL is only just noticeable, even if achieving it requires substantial upsizing of an amplifier’s power supply, output transistors, etc. Nonetheless, the differences I heard were dramatic -- far more than just being able to play music louder.The night before I unboxed the D 3045, the D 3020 V2 was still in my system, hooked up to the Paradigm Monitor SE Atom speakers ($300/pair) I wrote about in my first two columns. When fellow writer Philip Beaudette came over, wanting to hear the system he’d been reading about, I played him some tracks. He agreed that it sounded really good -- then said, “What more would most people ask for?”
The next morning, I unboxed the D 3045, swapped out the D 3020 V2, and put on the same track. I got a jolt as if I’d been shocked with 500V. “Rockin’ in the Free World” now thundered with dynamics that simply hadn’t been there the day before. Chad Cromwell’s bass drum hit like a punch in the stomach, the entire audioband was reproduced with much more clarity -- and I could turn it up louder. It was as if I were hearing a different pair of speakers.

Hsu reports the CCB-8 sensitivity in half-space at 94 dB at 1 meter for 2.83v, and our measurement of 93.8 dB largely agrees with their specification. Of course, half-space sensitivity converted to full-space sensitivity means a drop of 6 dB, which puts the CCB-8 at 88 dB sensitive full-space by their own specifications. That is above average for a bookshelf speaker, but do not mistake its half-space spec to mean it is a high-powered speaker that can handle THX Reference levels in a large room. The half-space sensitivity specification is simply the result of the setting it was measured in. In a medium-sized room, the CCB-8s can get louder than most people would ever want, but those who like loud-listening in a large room are going to need some much larger speakers.
Add four cheap components but it seems to work quite well. Point of crossing over and slopes remain virtually the same. You can buy resistors say 1R, 1R5, 2R2 and 3R3. Given the tolerances in LS50 drivers i don't expect anything less in Q100. Additional benefit is that you can set the level of the tweeter per your liking.
