Sensitive Monitors

I agree with Rr about the Reference 3A MM DeCapos. I own these speakers and they have gotten me off of the perpetual upgrade train.

However, Rr is not correct about the effeciency number. They are actually 92db eff., but they are a very easy speaker to drive because of the lack of crossover (uses a single cap, on the tweeter only). They do seem to be much more effecient than the 92db rating would indicate.

This is the first monitor that I've ever owned that had completely satisfying bass. I drive mine with a choice of amps including 3.5 watt 2A3 SET Tube, 8 watt P-P tube or 30 watt P-P tube. ALL of these amps produce more volume than I can use in my 14X12 room and the bass is deep (for a monitor) and accurate. Mids are excellent and highs are very satisfying to me. However, my non-i version is not as extended on top as some speakers I've heard. I prefer this as "bright" is not the sound for me.

For me, the Ref 3A DeCapos are the best combination of resolution and musicality that I've heard in my system. But they are not ultra high resolution (listener fatique?) or ultra musical (boring) like some speakers I've heard.

Also, there is a great following for these speakers, so, find a good price on a used pair, try them in your system and either love them or resale them at no loss (or very little).

Enjoy,

I have heard the JM Labs Mini U's and Dynaudio Special 25's at my local dealers showrooms (So I can only give a half informed report). From my point of view I much preferred the Dyn's (they were on the receiving end of an ARC system/ VT-100, LS 16.....). They had great extension, produced a very musical sound. The JM labs seemed to miniaturize everything...... I felt like I was watching little tiny performers on a little stage, almost like viewing a TV as opposed to watching a movie in a theater (these speakers were being driven by McCormick amps). Both speakers sounded good in thier own way, I just preferred the big vivid presentation of the Dynaudio's.

Having said all of this, I have never heard the Revel's and I think the Dyn's need some juice too.

Warren - I haven't heard the Revel's at all so cannot compare, but I used to own a pair of Silverline SR17 monitors that I had to sell to simplify my work system and pay some bills. They are one of the very few components that I've sold that I actually miss a whole lot, enough to buy another set if the opportunity arose. I forget how efficient they are, but they are not champs in that department. They do have a low end that they have no business being able to maintain given their size, and are as transparent as glass. They absolutely need a good stand to do their best. Utterly amazing and wonderful little monitors. I'd say you need at least 25 watts to make'em sing for you in an average size room. I tried them with my 8 watt SETs, and though they were marvelous at low volumes, they lost it pretty quickly with only moderate output. Outstanding build and finish too.

Warrenh, how about Merlin TSM's or Red Rose? I agree, 100wpc runs out fast with the M20's.

The JM Labs line of speakers are among the best in the industry.
" The JM labs seemed to miniaturize everything...... I felt like I was watching little tiny performers on a little stage, almost like viewing a TV as opposed to watching a movie in a theater (these speakers were being driven by McCormick amps)".

Others have stated that they didn't like the Revels.

Everyone has there own experiences/opinions when it comes to speakers. You will have to listen to them and form your own opinion.

With that said........
I've listened to the micro and mini utopia's and like the micro's a tad better. The utopia line is out of my price range so I own the JM Labs Electra 905's, next in line under the utopia's. I'm very happy with the full range sound for the size, bass is sufficient, mids and treble are above average for a stand mount monitor. My listening room is 11'x13' and use VTL tube preamp, power amp (50wpc) and never run out of steam.
If you think these will work in your system, by all means give them a listen. Only you can make the decision.
Just my $.02.
