The Piano - Michael Nyman

"The Scent of Love", a beautiful piece written by Michael Nyman, opens with a piano solo and is a great test of a systems ability to reproduce the piano and sudden dynamics. The first thing I noticed when comparing the W4S to the Parasound was the overall presence of the piano. The sound had more body to it, while sounding a tad more brittle and harsh on the Parasound. I found the W4S could easily hit the loud piano notes, with the same force that player used in the recording. Near the end of the piano solo, the music unfolds with a small posse of string instruments playing at maximum volume, the change in dynamics is quite shocking. Hearing it first on the Parasound, I felt my ears twinge a little, that feeling of sound compression being too much and wanting to turn the volume down. Nothing horrible, as the Parasound is still a great amp, but after hearing it on the W4S it was hard to go back. There wasn't a touch of twinge in my ears, I felt like I could have turned the volume up more and it would have only sounded better. These LS-6 speakers just love to be played loud. Sorry neighbors! One last note on The Piano soundtrack, I usually hate the saxophone track "Here to There" as it can be very harsh, but it sounded the best I've ever heard it through the SX-1000's. The alto's and baritones really took a spot in my room, with plenty of tangible body.

The Fall - Norah Jones

"Young Blood" starts out with a mean bass line that carries out trough the whole song. On the Parasound it sounded strong, but a bit bloated and out of control. At first that added strength to the bass seemed nice, but as the song progressed it grew tiresome. The SX-1000's on the other hand, were a bit more subdued and held the bass line under control. Individual notes were easier to discern and allowed for Norah's voice to stay on top of the soundstage.

"I Wouldn't Need You" is a much different track, very laid back, quiet and subtle. I listened to it first on the SX-1000's and immediately felt like I was in an intimate smoky club setting. Norah sat at the back of the soundstage, like she was sitting on a stool. The effect was great and closing my eyes really let my mind go. This song sounded completely different on the Parasound. Norah's voice was very forward, at the front of the soundstage and a lot of the atmosphere was lost. My ears would occasionally twinge on a dynamic peak as well. Overall, it was not bad, as her voice had a lot of presence and the band sounded clean and spacious, it was just a different sound. Personally, I really preferred the SX-1000's on this album and found myself getting lost in the music with ease.

The Nordic Sound 2L

Mozart Violin Concerto in D Major

First up was the Parasound and my first thought was a big front forward, almost in your face, sound. Peak dynamics again bothered my ears a bit, especially when the violin solo enters the stage. Switching over to the SX-1000's I heard a difference right away. The soundstage was set back a bit, spread out beyond the speakers, and felt more sonically accurate. The harshness was gone and I even turned the volume up a couple notches. I also noticed how planted the musicians are on the virtual stage. I could almost point out the 3rd chair cello player, as if every instrument had its own space and sat there. Through my years of listening to orchestra's through hifi systems, one thing that has bothered me about lower end reproduction is how a solo instrument will move around the soundstage with the change of notes. A violin playing a high 'B flat' might sound a couple inches from center than when the same violin hits a low 'D'. The SX-1000's give each instrument a very solid planting and it leads to a more tangible sound in my mind.

Prince of Persia: the Sands of Time

Since I use my home theater for both two channel music and movies, I like amps to deliver the dynamics of today's lossless audio tracks as well. Prince of Persia turned out to have some great test material. The impact and dynamics of the soundtrack were much more apparent using the SX-1000's. In the scene where Dastan first uses the dagger, the sound field projected by my speakers covered greater area and allowed the speakers themselves to better disappear. The lower frequencies during the siege on the sacred city of Alamo were tighter with more detail and quickness than the A23 could deliver.
