This review is a comparison between the Bluesound Pulse 2 and the Elac Discovery Z3. Both of these speakers serve as Roon endpoints so a comparison is in order. The Pulse 2 is $699 and the Z3 is $499. Because the Pulse 2 is bigger and more expensive than the Z3 this review is a bit of an unfair comparison. A more accurate comparison would be between the Z3 and Pulse Mini since they have similar specs and are both priced at $499.
The short version of this review is that the Pulse 2 is a better sounding speaker than the Z3 though the Z3 has amazing sound quality for its diminutive size. The Z3 has excellent bass and midrange but the bass and midrange of the Pulse 2 is quite a bit better. The Z3 has better extended highs than the Pulse 2 due to the Z3ās excellent tweeter array. The Pulse 2 has better stereo separation due to its larger cabinet size, speaker placement, and its ability to play in stereo. The Z3 is a mono speaker. Read on for a more detailed review.
The folks at Bluesound have really concentrated on the software side of things. The Bluesound app is excellent and works seamlessly with Roon. Itās leagues ahead of Elac. Though the Z3 is a Roon endpoint Elacās app is clunky at best. In fact, I can not get the the Elac app to recognize the Z3 in the chain. I have a permanent āNo Devices Foundā message on my Elac homescreen. Thankfully, Roon does recognize the Z3 and I have not had any issues playing the Z3 through Roon. Perhaps this is all that matters. Itās just that I donāt see Elac improving its app or its Roon integration any time in the near future. If mature integration is a priority I would go with Bluesound.
The Elac specs the Z3 at 140 watts. In the Z3, the two 4 inch drivers and two 1 inch tweeters can not keep up with the power and though Elac did an excellent job of trying to reduce cabinet resonances the Z3 still rattles and starts to sound a bit shrill at higher volumes. The Pulse 2 specs at 80 watts with one 5.25 inch woofer and two 2.75 inch midrange drivers and yet the Pulse 2 plays cleaner and louder than the Z3. Also, the Pulse 2 clearly has better, tighter bass and better mid-range than the Z3. In addition, the Pulse 2 is a larger speaker than the Z3 and the two midrange drivers are placed in the upper left and right corners of the cabinet. The Pulse 2 midrange drivers can also be used as left/right channels in the Bluesound app and therefore has a much wider, expansive soundstage than the Z3.
The one area which the Z3 sweeps the floor with the Pulse 2 is that Elac has two excellent tweeters where the Pulse 2 doesnāt have any. The tweeter gives the Z3 extended highs which is lacking in the Pulse 2. The Pulse 2 and Z3 were designed with different intentions and because of this both speakers have very different sound signatures. Overall, I prefer the sound quality of the Pulse 2 but the Z3 is impressive. If I can suggest just one change for Bluesound is that if they come out with a Pulse 3 in the future, they can easily integrate tweeters in the existing cabinet. There is quite a bit of wasted space on the front of the Pulse 2 which would allow room for tweeters in a future upgrade. The inclusion of tweeters in the Pulse 2 would improve the sound significantly in an already excellent sounding speaker.
The Pulse 2 has stereo separation set up in their software. The Z3 is a mono speaker and doesnāt have a stereo mode. Also, you can not pair two Z3ās in stereo mode with separate left/right channels. Being able to pair two Pulse 2ās into stereo left/right channels is crucial and this feature alone makes the Z3 not an option for me.
Iām amazed how tightly integrated the design of the Z3 is. How Elac fit all of this technology in such a small form factor is incredible. If I were looking for just one speaker for both TV and music I might choose the Z3. The Z3 is unobtrusive and gets the job done. Because the speaker array is so close together, however, you do not get an expansive sound like you do with the Pulse 2.
In both speakers there are equalizer controls that work from the Bluesound and Elac app. If you want a bit perfect lossless signal path coming out of your speakers I would recommend keeping the equalizer controls turned off. With the equalizer turned on the sound quality form both speakers are muffled and veiled. The degraded signal is worse with the Z3 than it is with the Pulse 2 as shown in the signal path in Roon.
If you are looking for an unobtrusive speaker for your kitchen or bedside table I would recommend the Z3. As of now, I have a Pulse 2 and a Z3 atop my refrigerator in my kitchen. The fact that the Z3 has its volume control on the front panel means I can control the volume from the Z3 without having to go to Roon to do so. The volume control on the Pulse 2 is on the top of the speaker so itās unreachable when the speaker is on top of my refrigerator. Also, perhaps, the Pulse 2 might be too much speaker for my small NYC kitchen. We will see if the Pulse Mini is a better fit.
For those of you who think looks is important I am going to have to declare this battle a draw. I am an avid minimalist and the black slab of the Pulse 2 is stealthy. A friend of mine came over to listen to a pair of my Pulse 2ās which I had set up in adjoining rooms. He had no idea where the music was coming from, even though he stared right at them. He was so confused he remarked that the music was coming from the light bulbs. Conversely the Z3 is equally beautiful. Though its richness is difficult to discern in photos the real chrome accents and wrapped metal make the Z3 an exercise in form follows function. I also love the flat top of the Z3. Hopefully it will be easy to clean but its dimpled, rubberized surface could become a sticky dust collector.
In the end, because the Pulse 2 has superior sound quality, can be paired to form proper left/right channels in stereo mode, and has better software integration with Roon, I will be returning the Z3. I will get the Pulse Mini to compliment my Pulse 2ās. I am not sure how the Pulse Mini would stand in comparison to the Z3 but at least I know that I will be able to integrate all my speakers with Roon and the Bluesound app seamlessly without issues.
Also, someone else on another thread suggested I buy my speakers from World Wide Stereo because they have a liberal 60 day return policy. Their customer support is excellent and so is their knowledge. I ordered speakers one afternoon and the very next day they arrived at my front door with free shipping. Outstanding. Amazon Prime doesnāt offer this level of service. It took me awhile to familiarize myself with the Roon and Bluesound app and I wanted to take my time with the Pulse 2 speakers. Only then did I order the Elac Z3 to compare. If I ended up liking the Z3 more than the Pulse 2ās I was within the 60 day window if I wanted to return the Pulse 2ās. I am keeping my pair of Pulse 2ās and Iām exchanging the Z3 for a Pulse Mini. I can not thank World Wide Stereo enough for being so supportive. Thank you.
