The most dynamic & transparent bookshelf

Speaking of power amp, yes I can assure that the Class D Audio power amp is indeed outstanding, I've got a NAD 3020i, the sound came out from Diamond 122, is bass overbloat, a little warm and less shine on treble, most importantly the sonic does not shine, I can spot this in classic track like Tutti! - Igor Stravinsky - The Firebird - Finale. So the things achieved on the Class D Audio poweramp is neutral, transparent and dynamic tonal balance. Also I notice at higher volume Class D Audio power amp able to control the woofer cone, absolutely fantastic! For small to medium, NAD 3020i still not bad, but not to the extent to cover all music styles and dynamic. So my current audio chain is pretty there, EXCEPT I need a more powerful mini monitor to complete my journey, sound not realistic huh?

Power amp specs can't be trusted. For example,

OK Zd542, you're preaching to the choir. I worked in the A/V industry for over 20 years, mostly with high end audio, and have always used quality amps like Threshold, Pass, etc. I am fully aware of what you are saying, and in no way whatsoever was there an issue of inadequate power in what I said in the previous post. As I stated, the problem was that the speakers sensitivity was just too low.

You should also notice that I have not made a speaker recommendation as well. I have only been trying to get the OP to understand that if a certain speaker of 86db sensitivity does not play loud enough and is lacking in dynamics playing loud, then a different speaker with that same sensitivity will not do it either, and lower sensitivity even worse. Sure, there may be an exception to this, but IMHO, I seriously doubt it.

The reason is that I can't think of any small speakers that will do what the OP is asking.

Again IMHO, the Coincident Triumph Extreme (94db) or the Reference 3A MM de Capo (92db) will likely satisfy his desire, although he will need to increase the budget or buy used.

As far as the recommendations listed here, and again, IMHO, the Goldenear AON 3 (90db) may have a good chance to work for him. I have not heard them, but have a friend that has a pair. This guy worked with me for a few years, and still works in the A/V industry. His company acquired the Goldenear line after hearing them at a show, and he chose the AON 3 for himself saying they sound very dynamic and much larger than one would think for their size.

Tls49: Thanks again for the recommendations, I had seen those 3 you have recommended, indeed look attractive to me, though price several folds high, except the Goldenear AON 3.

"OK Zd542, you're preaching to the choir."

You're right in that I figured you already knew this. I made the comment because I thought some of the other posters may not be aware. I should have put some type of disclaimer in.

The only point of yours that I would mention is that instead of getting more efficient speakers, you can get a more powerful amp. Yes, I know the OP already has one, but given his demands, he may have to modify his approach. Look at this once more.

"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!"

If the OP wants those results, he must do some listening. There's no way around it. That's quite a list. I'll mention the reference again. Without more input and work on the OP's part, I'm not convinced that what he's asking for is even achievable. And even if it is, the price of it all may be more a lot more than he's planning on.

Zd542: Thanks for your reminder. Yay, I'm thinking is that possible too, also I'm starting to save cash now, so it just matter of time, eventually I can get a pair that satisfied me, so I need very careful thinking, consideration, and other measurement whenever possible. A pair of TAD reference 1 definitely is neverland for me but at the same time is dreamland for me, not that it's not the best, it just that I'm not capable of :(
