MBL 101e's vs. Soundlab U-1's


I have decided to change my speakers. I have had Dynaudio Temptations for 2 years, and for the past few months I have felt that there is something missing. Bass presence, ambience, I really wasn't sure. My system has been very stable over the past year: a Boulder 2060 amp, and ARC Ref3 preamp and an Esoteric X01 limited cd player. That was actually a recent switch, from the Meitner gear. I decided to listen to MBL 101e's and Soundlab U-1's. I picked those speakers since along with Von Schweikert VR 9's those were the speakers that I remember giving me great, almost spooky "you are there" performance. There are no Von Schweikert dealers in the area, and the VR 9's are too expensive fpr me anyway. I considered the VR 7SE's, but there is nowhere to listen to them.
I started with an extended demo of the MBL's. I found that the MBL's have some strengths that the Dyns don't have. Unbelievable staging, bass (not boomy), and a sense of presence and ambience
that the dyns actually do approach, but do not equal. I brought several different types of music. I started with one of my very favorite cuts, "The Maker', by Emmylou Harris on Spyboy. There was a palpable presence of the musicians, with the drum thwacks at the end reverberating in my chest. As Valin says in his review, the speakers need to be played at a somewhat higher volume to really open up, but not overly loud. As was mentioned by a few people the sound did ring or was kind of "steely". Ron, the dealer, said that he felt that it was due to the MBL preamp, rather than the speaker itself. He changed to a Griffin pre, and the sound was much smoother, at the expense of some dynamic presence. Next up was Johnny Cash, American Man IV. This is meant to be played at a lower volume than EmmyLou. It sound great, with Johnny centered and the guitars to either side. Finally, the new Dixie Chicks, higher energy Southern rock. All the MBL strengths were there, staging, imaging, dynamics, etc.
The downside to these speakers is that they are very difficult to set up. The room acoustics can be tricky and the required amplification is very expensive. Hopefully, my Boulder 2060 is up to it.
Next up were the Soundlabs. Yesterday, I heard a convincing demo of the Soundlab U-1, not the U-1x which is apparently the updated model. These are scary good. I brought the same cuts that I used during the MBL demo. BTW, in each case the speakers were driven with a powerful SS amp, and a tube preamp, in the case of the Soundlabs.They actually sound very similar to the MBL's. The pros are that my Boulder will drive them without any problem. They also need relatively less room treatment, due to their radiating pattern. They are incredibly dynamic with an unbelievable soundstage. There is excellent taut bass. The demo was in the house of the local dealer, in an old living room with almost no treatment. The room is substantially smaller than mine.
The con is their size. I have to do some meaurements to make sure that they would fit into the constraints of my room.
I am having a ball with this next phase of my audio life. After these two demos, it's hard to see why people would be satisfied with box speakers. Although, given the constraints imposed by these speakers, it can be difficult to get either working optimally.

diff strokes for diff folks. listening preferences determine speaker-owner suitability.

i owned U2s, and couldn't ditch them fast enough.

i listen to lots of R&R; the fact that you like SLs implies that you do not. they're coherent to the max, and great for choral / orchestral / chamber / jazz, but they are not going to do a thing for led zeppelin.

Rhyno:

I'm afraid I have to disagree with you. My SL Majestics will rock with the best dynamic speakers in the world! The new Soundlab PX panel technology is way more dynamic than previous iterations.
David - it's always interesting to come across a line of thinking and taste that mirrors one's own so directly. I have owned several Dyn's, currently owning the C2's - I've always loved the Dyns, listening to a wide variety of music, and also for HT / movies.

Like every addict, I often think about what I'd try next. In addition to going up the Dynaudio line (the Temptations would be a likely target), I've also read a ton of reviews and, reading between the lines, the speakers that have really intrigued me include the MBL's and the Soundlabs, so it's interesting to here your impressions - thanks for posting them.

The one other line that really intrigues me is the ATC's. Depending on the side of room you're trying to fill, the ASL 100's or 150's would just be a lot of fun to audition.

I've got a local dealer for Dynaudio that does a great job, but no dealers for the other lines, so there's no way (easily) to get a taste.

Hope you end up in a good place :-)

David,
Just to cast one vote, I would rather have your Dynaudio Temptations than the MBL 101. In fact, the MBL would not make my top favorite 15 speaker list :^).

On the other hand, I do love the Sound Labs, coherency like nothing else.

As Kirk said, I hope you wind up in a good place, there are more great speaker choices today than ever in the history of audio (in my opinion).
