The Kilpsch RP-8000 floor standing speakers is next entry in the highly praised reference premier line of audiophile home theater speakers, joining the current, and perhaps, replacing the RP-280 model. With an all new tweeter design, the RP-8000 is no doubt poised to target those who do not want to compromise sound quality and demand nothing but the best. I can safely say the RP-8000 exceeds expectations with flying colors. As such, because our perceptions of sound differ, as well as other variables such as equipment settings and room acoustics, I could not wait to test the RP-8000 thoroughly with different playback scenarios!
Upon inspection of the RP-8000 speakers, I was pleased to note that they were packaged extremely well. The speaker was completely enclosed with a soft cloth cover, with a second set of plastic on top of that. Additionally, the RP-8000 is supported by three Styrofoam blocks. I would also strongly suggest you have another person help you remove the speaker from the box, as the large box was rather awkward for one person. I found it easiest to lay it down and have someone pull box away from you as you gently pull. Once opened, you are treated to one of the most beautiful piano black appearances you will ever see. To the touch, the speakers are extremely smooth and rounded perfectly on all sides. The gloss is just impeccable and is absolutely gorgeous. In addition, the piano black finish surprisingly did a fabulous job of concealing the fingerprints, though you will notice them up close. The included cloth easily wipes them away. Nonetheless, the speakers are absolutely stunning to see in person; no picture will be able capture the full elegance of the glossy finish. If you are on the fence on which variant to pick (Ebony, Walnut, Piano Black), I would strongly suggest the piano black variant, if of course your budget allows for the extra cost. Physically, the speakers are quite heavy, coming in at roughly 60 pounds, but were actually pretty easy to maneuver. Additionally, at 43 inches, depending the size of your TV and your entertainment furniture, they might come close to being flush with the top of the TV. On the back of the speakers, the RP-8000 are Bi-Amp ready with two pairs of speaker terminals (one set each for low and high frequency respectively). Lastly, the protective grill magnetically sticks to the front of the speaker. Overall, the RP-8000 are sure to impress and were fairly easy to setup!
For testing purposes, I used a Pioneer Elite VSX-LX303 receiver to power the speakers, tied together using Audioquest 14 AWG X2 speaker wire that was manually cut from a 100ft spool. The VSX-LX303 receiver was also plugged up to the wall using an Audioquest NRG-Y3 AC cable. Additionally, I did not Bi-Amp the speakers and only used one set of terminals (bottom set). For playback of movies and music, I used my Sony Ultra Bluray UBP-X800 player. For my first test, I listened thoroughly to my collection of lossless music in a 2.0 channel configuration, as I wanted to specifically focus solely on the audio capabilities of the RP-8000. The LX303 receiver was set to Pure Direct mode, which disabled any additional processing so that the source passes unaltered to the speakers. Connectively, I next wanted to shift my attention to movie playback, with first testing the RP-8000 speakers by themselves (2.0) and then subsequently move to a standard home theater test using a standard 5.1 setup.
During music playback, the first genre I ran through was some of my favorite classical pieces. I played through a high resolution copy Schumann's String Quartet (192 KHz/24 Bit/2 Channel PCM) that was encoded on a Bluray audio disc. The first thing I noticed was the instrument separation of the quartet was extremely prevalent, with high and middles frequencies extremely clear and pronounced. There was an intimate warmness to the sound that just grabs you! An almost surreal moment was that I could easily isolate each performer during the performance, yet still be able to experience the whole encompassing soundstage. It is definitely one of those moments where you just smile, especially when you have the lack of words to describe what you are hearing. In addition, you can sometimes hear other nuisances such as the inadvertent sound of the string when pressed against the wooden fingerboard or inhales of the performers. I was actually able to keep the receiver at roughly -50db in volume (LX-303 decreases and increases in -0.5 dB increments) and I did not feel the need to turn it up! For rock and metal genres, the RP-8000 actually did an amazing job! The sound quite vibrant. In addition, I did not notice any muddiness or hollowness that I sometimes hear when rock music is crushed during the mastering process. Symbols and drums were clear and punctual as well as the guitars. The middle and higher frequencies seemingly breathed as much as it could, despite the over use of compression that plagues modern rock music. It was refreshing, nonetheless, that the RP-8000 handled rock and metal as well as it did. For more bass orientated tracks, such as Rap and Trance music, the RP-8000 did an amazing job with the lower frequencies. It was punchy and clear, and yet it did not struggle to reproduce a low sound. In addition, where rumbling would occur had a subwoofer been present, the RP-8000 did an exceptional job of clear distinguishing the drops in low frequencies. With 32 Hz on the low end of its frequency response, this was pretty amazing and even more so given a two channel configuration! Granted, keep in mind the RP-8000 can only do so much until you add a subwoofer to handoff what it cannot reproduce. On more Hip-Hop instrumental tracks, and especially those with some Jazz influence, the lows, middles, and highs were all distinctly heard similar to my classical music. Switching to World genres and movie soundtracks, again the RP-8000 demonstrated extremely clear and punctual highs and middles. The lower frequencies were handled quite well once again. Over the course of several listening sessions that lasted several hours, spread out over multiple days, the RP-8000 continued to dazzle with amazing sound. The warmth and clarity was a real treat to hear!
With exceptional music playback performance, I next want to focus my attention to movie playback. As with music, I set the receiver to Pure Direct mode. During my 2.0 channel test, the RP-8000 was able to maintain extremely clear dialogue, while simultaneously providing nice depth to action sequences. In the opening battle sequence of Gladiator (DTS-MA 48 KHz/24 Bit/5.1 source), I could easily hear battle dialogue as well as the background soundtrack. The soundstage was full and breathed new life into the movie; keeping the volume at a constant -40.0 dB, it was loud enough to completely fill downstairs. Furthermore, subtle sounds in the background, such as weapon clings and horse cries, were heard as well. In dialogue heavy scenes, the RP-8000 did an exceptional job with maintaining crystal clear dialogue, almost as if I had a center channel installed. Moving on, I switched to The Patriot to see how the RP-8000 would handle an uncompressed PCM track (48 KHz/16 Bit/5.1 source). It sure did not disappoint! I noted similar results as I had in Gladiator during battle sequences; drums of each army as they are lining in formation were crisp and sharp as well as the musket fire. The soundtrack, once again, was clear and vibrant. Switching to a full 5.1 setup, for both movies, the RP-8000 switched to more of an accompanying role with the dialog now pushed to the center speaker. The soundtracks of both movies still maintain excellent clarity. During the battle scenes, the center channel and the RP-8000 simultaneously worked back and forth off of each other fairly well. Once someone would finish talking, the RP-8000, while still playing the soundtrack in the background, would pick up the complimentary sound in the action scene. As soon as you heard musket fire on the RP-8000, it was followed immediately by rumbling of the handed off lows of the subwoofer. Additionally, debris and off side battles between movie extras were heard in the two surround speakers. The sound completely bewildered me, completely engulfing the room as well as downstairs. In Gladiator, the RP-8000 once again dazzled with sharp high frequencies of sword blows and ambient battle sounds. Suffice to say, with the RP-8000, all you can do is grin with excitement. Overall, I think most will be completely blown away by the sound.
In conclusion, the RP-8000 is an exceptional piece for any audiophile's home theater system or as an upgrade to existing system. Physically, the built quality was top notch and the quality is just staggering. Furthermore, the reflective glossy black piano finish absolutely blew me away. Detail is exquisite with smooth rounded corners to provide a seamless and detailed transition on either side of the speaker. Performance wise, the RP-8000 handled my vast music collection with ease and I was able to enjoy a wide variety of genres. For me personally, the soundstage and overall clarity on the RP-8000 is best that I have personally heard from a speaker. Additionally, movies performed similarly, providing rich detail and an incredible soundstage that you have to hear to believe. In the end, for those who demand an exceptional audio experience, the RP-8000 might be the solution, provided of course that price is not of concern. With that said, the RP-8000 comes highly recommended.
