Review: JMLab Electra 920.1 Speaker

Category: Speakers

I upgraded from PSB Stratus Goldsi to the JMlab Electra 920s. I also have the Electra CC 30 center and two pair of the Electra SR 30 dipolar rears. I am very impressed with the JMlab speakers. I use them for both home theater and 2-channel music. They are great for HT but really shine with 2-channel music. I believe the one trait that separates good audiophile speakers from great audiophile speakers is the soundstaging and imaging. This is usually the first quality of the speaker that I notice whenever I go to audition speakers. The JMlab Electra 920 center imaging is very strong with 2-channel music. So strong that as a matter of fact most of my friends when hearing them for the first time get up and walk over to my center channel speaker and put their ear to it to check if it is on.

Some of the qualities that I like most about the JMlab Electra speakers are the tight bass, the transparency (the speaker seems to disappears in the room), and as I have previously mentioned but want to state it again for emphasis is the BIG soundstage and very good imaging. The soundstage is both wide and deep. I am sure that someone with more experience than I could find some faults with this speaker, but I cannot. I guess when I start finding faults it will be time to upgrade.

As compared to the PSB Goldsi the JMlabs are much more transparent (the speaker disappears), they have a bigger soundstage, and much tighter base that the PSBs. The PSBs are a laid back speaker with rolled off highs. The JMlabs are more forward and a bit livelier in the treble region than the PSBs. Do not get me wrong the PSBs are a great speaker but for almost twice the price, the JMlabs should be much better and they are.

I cannot really compare these speakers to the M&K S-150 system. The M&K system is a THX system. A THX system may be a good idea for a system that is strictly used for home theater but I am into to 2 channel as well as HT. Shortly I will be upgrading to DVD-A and SACD. I love M&K speakers for HT. However, I also enjoy 2-channel music. I like rock blues Eric Clapton, blues BB King, and jazz Dianna Krell just to name a few. The first thing I noticed with the M&K system is that it sounded very boxy with 2-channel music. You could see exactly where the music was coming from. This would be the exact opposite of transparent quality, which the JMLab speakers show very well.
