Dartzeel 108

hi Rodrigo,

i've not tried the darTZeel NHB-108NS/JM Labs Micro Utopia Be combo; however i have listened to the dart with a number of speaker systems and have listened to the Micro Utopia Be a number of times and i do have an opinion on how the combination likely would sound.

the Micro Utopia Be is a very transparent sounding speaker, that Be tweeter does not suffer 'ordinary, decent sounding' amps happily. it demands naturalness and refinement and will pay those characteristics back with high level performace in spades. at 89db efficiency and a 8 ohm load the dart's 100+ watts should drive the Micro Utopia nicely. and amps do not get more refined or have sweeter more transparent mids and highs than the dart. the dart also has wonderful microdynamics that the Micro Utopia will communicate accurately.

i would be surprised if this combo was not special. and if your sources or speakers are upgraded the dart will always be a worthy match for any additional performance.

one additional note; the dart 108 is reported to be an ideal mate for the Magico Mini II; which is 84db efficient, 4 ohm load (assuming the right medium to small sized room). i think the Micro Utopia Be might be a similar type sounding speaker (but much easier to drive) if not at the same level as the Mini II.

Vaipe,
Just wanted to say that I agree with Mike's accessment of the dartzeel amplifier. In addition to it's absolute world class refinement, purity, transparency and resolution, it also floats grainless 3D images in an open spacious layered soundstage. It sounds like music.

Good luck,

Vaipe-

I owned a 390s. Eventually I found a Wadia I liked better that also had volume control. Then I finally took the plunge and bought an Ayre K-1xe preamp to compliment my Ayre amp. Wow was I blown away by the sonic improvement. To this day it was the single biggest improvement I ever made. Everything got clearer and more defined. The soundstage widened more than I thought possible, and the dimensionality went from what I thought was 3-D to what really is 3-D (AKA more refined). I've since come to believe the preamp is the single most important component after speakers.

The Dartzeel is an excellent amp but you're still missing a very important ingredient. Adding a better amp is an inferior upgrade choice IMHO.

Heck don't take my word for it. Seek out a good deal on a used preamp and try it. If you decide I'm full of it resell it and upgrade your amp.

I just sold my speakers to a guy who had the micro utopias. He had the same issue as you. He decided to change speakers because the micros were not giving him what he wanted.
The speakers were Verity Parsifal Encores.
Just some more food for thought.
