The most dynamic & transparent bookshelf


I get it when I hear some speakers like Wharfedale Denton 80th Anniversary, they are musical, detailed, but not on extreme dynamic, it can go pretty low and loud, but still lack a bit more powerful punch. My next aim for powerful speakers, will be something near perfect immune to distortions, must be extreme dynamic, go very loud and does not make the sound quality collapsed, also I insist to stick with bookshelf size, few options in my mind:

Ascend Acoustics Sierra 1 (with NrT upgrade, worth?)
Mark&Daniel Ruby
Dynaudio DM 2/8
Proac Response D2
Soundfield Audio Monitor 1

For Dynaudio and Mark&Daniel, I have concern on power and drive efficiency, though I'm using a Class D Audio SDS-400C power amp, it work damn good with my Denton (warm + transparent gear goes really well). My considerations based on factors in this order: price, near full range dynamic, neutral and transparent sonic quality, availability (as I'm from Malaysia, not easy to achieve those speakers), and last your opinions? Any other recommendations? Once again, I'm not looking for speakers with colorations, must extremely dynamic, dead neatral and transparent without snake oil!

Dayglow: I have a check on the spec, it seems it does go low enough? 56hz -6db, hmm...
"Zd542: Yes, it's hard but I think Proac Response D2 suit me well, dead neutral and amazing bass range, for your info, I'm driving my speakers using no hype technology products like JDS Labs ODAC, Blue Jeans cables, and Class D Audio power amplifier, no preamp/ CD player / phono etc..."

When I read through that post, the level of detail you give would suggest that you've actually done some thorough listening to the speakers. If that's not the case, you may want to rethink your strategy. It's not possible to come up with that kind of detail from specs. Even if you use reviews, more things can go wrong than right.

Have you heard anything that you would be willing to buy? Even if its out of your price range, it can still be used as a reference.

Agree, however, since very loud and dynamic at loud volume are very important, you should be concerned with speaker sensitivity. If the Wharfedale Denton at 86db was not adequate, then it will be best to look at speakers with a higher sensitivity, most likely in the range of 90db and above.
Sensitivity specs are useful but can be deceptive. Sometimes they do not
apply to the lower frequencies if present or sometimes they are good
because low end extension is limited so take them with a few grains of salt.
Many smaller monitors do not do the lowest octaves much and are much
easier to drive to high volume. It's the lowest frequencies that require the
most power out of the speakers to deliver with flat response. Power
demands increase exponentially with lower frequency as else held
constant. You need more power or larger speakers or both to do it.
Smaller speakers in larger rooms will tend to distort more if asked to play
loud and deep. Small rooms are much easier and the world is more your
oyster there. Also the good news is not much happens with the lowest and
highest octaves with most music so those on a budget can practically cut
some corners there when needed unless you are into organ music or gotta
hear the lowest frequencies that might be synthesized on occasion.
