Default Logitech Z-2300 vs Audioengine A2

I have a set of Logitech Z-2300 speakers and might upgrade to a pair of Audioengine A2 speakers. I'm looking for a wider sound stage and greater clarity, I've heard that the A2s are very good. I enjoy the bass from the Z-2300's, but I find it lacking in clarity. Has anyone tried both these speakers? How do they compare?

I'll be using my DIYEDEN SVDAC04-USB with a Little Dot II++ amplifier, RCA outputs on the amp will go the speakers (headphone jack for HD595s).

I haven't heard the A2s but you can't really escape the laws of physics, small speakers are simply not cable of bass output you may be looking for.

If you like your bass you might want save up for the A5s (or speaker of similar size). The A5s also have sub output, something that may come in handy down the road.

The Z2300 sub woofer has 2 RCA output jacks (L and R), would it be safe to hook up the A2's to these output jacks? That way I would be able to use the A2's with the Logitech sub woofer.

Yes, but you must make sure A2's have 8 ohm impedance, NOT LESS ! Otherwise you might damage the Z-2300's amp !

No, the A2s are powered speakers, the RCAs are meant to accept a low level input from a soundcard or other source. The Logitechs are using the RCA connectors as speaker terminals, if you hooked them up to the A2s it either wouldn't work at all or you would damage them.

In that case, I could split the RCA outputs on the Little Dot II++, feed one pair of inputs to the Logitech sub woofer, then the other to the A2's? The signal is split, but the A2's and sub woofer have their own amps. How would that sound?

Well... it probably wouldn't sound the best. Your talking about a multimedia "subwoofer" so it's not cleanest bass in world. The A2s are full range so there would be (probably pretty big) overlap between the A2s and the Logitech sub where they would both be covering the same frequency. That probably sound pretty weird due to the high crossover point of the Logitech.

Short answer; I think you'd probably end up ruining the sound of the A2s.

I'll probably pick up the A5's since I'd end up selling the A2's for the A5's anyways. It's too bad AudioEngne's "audition" offer doesn't include us Canadians since we have to buy them through Mostly Digital : Cool Tools for your Digital Lifestyle instead. For all I know, they might not sound much better than my Z-2300's

I was able to get the speakers locally from WestWorld Computers in Vancouver. I ended up getting the A2's since they were smaller and would be easier to place on my desk. They also have their bass ports on the front whereas the A5's have them on the back, which is helpful since my desk is right up against the wall.

I first tested the pair in store, the speakers were hooked up the mini output jack on the back of an iMac. I listened to a few songs, but "SexyBack - by Justin Timberlake" caught my attention. I personally don't like this song, but whatever instrument was being played during the intro sounded like it was coming from 3 feet in front of the speakers! I found the sound stage to be quite decent, it was as if the sound coming from about 2-3 feet further than where the speakers were positioned.

Later in the week, I hooked up an RCA audio switch to compare the A2's directly against my Logitech Z-2300 speakers. Generic cables were used to hook up the A2's to the switch, and a RCA to 1/8" adapter was used to hook up the Logitech Z-2300's. My source is a DELL M1210 laptop hooked up via USB to a DIYEDEN (Musiland) SVDAC04-U using the rear RCA outputs.



I stacked a few of my computer science textbooks to create speaker stands and placed the speakers beside each other. The "outer" speaker set would probably have an advantage since it's further apart, but I address this by swapping their positions during testing of each pair.

At first, I tried to determine the sound stage for each pair. Even with the A2's in the "inner" position, they still have wider sound stage compared to the Logitech's placed in the outer position. With the A2's in the outer position, there was no contest.

Sound clarity on the A2's is noticeably better, having an easier time hearing the different instruments, they weren't too bright either. I also noticed that it handled the voice of Celine Dion in "My Heart Will Go On" very well compared to the Z-2300's which I found was a little distorted and fatiguing to listen to. I'm not sure how to explain it, the voice is clearer, more natural, more centered, but not overly bright. On the Z-2300's, her voice sounds a little synthetic, less clear but too bright? Perhaps "too bright" is the wrong way to describe it, but it I found it difficult (hurting) to listen to.

Being used to the Z-2300's "thumping" bass, when I tried to listening bass I was greatly disappointed with the lack of bass compared to the Logitech Z-2300's. However, the first time I hooked up these speakers was actually at my girlfriend's house and at that time I thought the bass was plentiful, punchy and above all very clear. You could clearly hear the instrument creating the low notes, but it's not loud, you have to listen for it. It's just when compared directly against the Z-2300's (which has a 120 watt subwoofer) the bass "seems" lacking.

I then hooked up the Logitech sub to my headphone port, and continued using the A2's through RCA output. Essentially, I tried to "combine" the best of both worlds. At first, I was quite blown away, all the clarity and sound stage was there, along with the decent bass. The low notes (thumps) we very centered, though I'm not exactly sure how this works. When I turned off the A2's, I could hear all the low notes coming directly from my right (where the sub is placed). When I turn off the sub, I could clearly hear the instrument creating the bass coming from center between the A2's, though there was no "thump". However, when I turned both the A2's and sub on, the bass "thump" magically moved towards the center of the A2's!

After further testing of my hybrid setup, I came to notice that the low notes or "thumps" produced by the Logitech sub was actually very muddy compared to the A2's alone. The instrument creating the sound of the bass was unclear. The "thumps" I heard from all my songs all sounded the same. When I turned down the volume of the sub, the clarity came back. But with the sub volume low enough to retain the clarity, there isn't much improvement in bass, it's noticeable, but I don't feel it's worth turning the sub on for. I've since unhooked the sub and have been listening to the A2's alone, and they sound incredible without a sub. Perhaps I will be able to find a better sub to pair with the A2's, any recommendations are welcome.

In my opinion, the A2's sound much better than the Z-2300's, the sound is clearer, voices are more centered and focused (with the Logitech pair, instruments seem to overpower the singer), voices sound more natural, and the sound stage is much wider. The A2's don't provide deep bass, but at the same time they were good enough to have me realize that the sound created by the Logitech sub was very "muddy" in comparison.
