Description

Hifi is a journey, not a destination.

I played piano, alto sax and clarinet, subscribe to the symphony, and enjoy the jazz and blues scenes in Seattle. I'm familiar with live music. My music interests span from classical to jazz, blues, and other stuff (rock, folk, funk, electronica, etc). Favorites include Michelangeli, Argerich, Furtwangler, Montoya, Piazzolla, Melvin Taylor, Junior Wells, Lionel Hampton, Jimmy Smith, Brubeck, Jeff Beck, Stanley Turrentine, Jeff Buckley, (early) Chicago, Zeppelin, Cream, Groove Armada, Massive Attack, Nightmares on Wax, Daft Punk, etc., depending on mood.

I've been interested in hifi since I was a kid. Pioneer in the 70s, Counterpoint in the 80s, Audio Research in the 90s... I grew cynical of the direction the hobby took in the 2000s. For this system, I wanted to express my personal sonic priorities beyond what is available in the commercial market. My goal is to communicate music's impact, soul, emotion, and nuance. I want my system to play with alacrity, gravitas, affection, protest, or just funkin' good times. If it can't conjure a wide range of emotional reactions, than it simply won't satisfy. After years of effort, this system plays small-scale music with softness and delicacy, while large-scale music like Rachmaninoff, Mahler and Zepplin is sublime, projected with bone-crushing power like a big Steinway D or Audi RS6.

Creating a memorable sound system is like cooking a delicious meal. In the beginning, I bought great ingredients, all the components and parts that comprise my playback. I quickly learned that ingredients without experience and talent aren't enough to create a memorable sound system. It took many years, failed experiments, and a few successes to get here.

Experiencing thoughtfully-implemented multi-way horns was an epiphany. My high points are Josh's wonderful Electronluv system at VSAC 2003, and Romy's Macondo in Boston.

The speakers are the heart and soul of my system. I named them Shibusa, a Japanese word describing an aesthetic of simple, natural beauty. Shibusa refers to things that exhibit: Elegant simplicity. Effortless effectiveness. Understated excellence. Beautiful imperfection. They began as Edgarhorns, purchased new in 2005. After years of learning, stupid mistakes, and epiphanies, I could write a book on horn speaker design and still barely scratch the surface. Horns are like F1 race cars - silly high performance under skilled hands, while unforgiving of fools (I made my share of foolish mistakes). My Edgarhorns evolved with the addition of stereo sub-bass channels (Danley Sound Labs horn subs, used in IMAX theaters), upper bass (full-size 142 hz tractrix horns from John Hasquin loaded with Fane Studio 8M drivers), mid-range (Coral M-100 drivers in 400 Hz tractrix horns), and HF (magnesium Fostex T500A Mk II), and crossovers and amps to support them. There is literally nothing leftover from the original Edgarhorns, but they were a great education.

There are a total of 10 drivers and channels (5 per side). All filters except sub-bass are first order, with both speaker-level and line-level filters. First order filters are beneficial to minimize phase spinning and other time domain pollution, but require better performing drivers due to more overlap between the drivers. Integrating all the horns, drivers, amps, and crossovers in my room was challenging, more difficult than I ever anticipated, and a required a very long learning curve. I use both measurements and subjective listening to balance speaker placement and individual channels. Listening room is 16' x 18'. The effortless and deep-bass, startling dynamics, and full-range clarity distinguish Shibusa from conventional speaker designs. There is NO harshness or 'horn' sound in Shibusa, according to visitors - even those with anti-horn bias.

Without the kind and generous support of horn thought-leaders like Dr. Bruce Edgar, John Hasquin, Steve Schell and Rich Drysdale, Romy, Jeffrey Jackson, and ESO, it would have been very difficult for me to achieve as much as I have. Thanks to all who shared in this journey!

Larry-
You have shared your experience with many people here, and I appreciate your comment.

It's been a long journey, and today I'm about as far as could be from the original high-power low-efficiency set-up. It's been tons of fun!

Kleonard-
Well, you may be right. The transport is the only part of the system that I haven't experimented with. I'll have to get smarter on this. Thanks for your input.

I have the DVP-9000ES also, and it is a horribly sounding transport. Believe it or not you could do better with a Denon DCM-370 ($300) cd player as a transport. If I were you I would experiment with better transports for cd playback. If your cd playback sounds so good now imagine how it will sound with a better transport. I use a Meridian 500, which is better than both, but I A/B ed the DVP-9000ES with the $300 DCM 370 (used $100) and it was no contest, the DVP-9000ES is that bad, (its very harsh and slow). Just a suggestion for something you might want to think about.

System edited: Added Lamm L1 preamp to system. The L2 does wonderful things to playback. The sense of acoustic space, instrument scale and location, humanizing voice and "anti-electronic" signature is a treat. But there are some idiosyncracies about L2 playback that bother me. Specifically, the L2 has an upward tonal balance and a slight but noticable compression of dynamic range. Also, two full-size chassis is impractical. I want to evaluate the L1 in the hopes of retaining the L2 goodness, while addressing its problems.

Howard, first impressions posted. Having fun and always learning. This is like an advanced course in speaker design and room acoustics. It takes some effort to get everything together.

How's the K-horns? Are you listening to them yet???

System edited: Added Edgarhorns to system. Position is limited by available space. Not even close to proper set-up. They are located outside of the Circes, almost at the sidewalls and 5 feet to the front wall, 10 feet to listening position. Exposed crossovers, wires everywhere, wooden horns temporarily supported by anything available, until furniture casing is built. My concern was not to lose the endearing strengths of the Circe, while gaining a sense of effortless agility and improving dynamic range. After getting past the kluged set-up and clutter, the first impression is promising. I'll keep it brief. Startling, effortless sound pressure gives a sense of aliveness and agility. The enitre room is pressurized with music information. This is not about loud, it's about loading the room in its entirety, even at low listening volume. Notes are separate, individual and organized. Still nice, round and warm rather than choppy and etched. Spatial information is about 80 - 90% of Circe - still very good. Room placement and optimization will take more lots of effort, based on size and weight. Much fun work yet to do!

Drumroll please..........

System edited: The Seismic Sub is in the system. This is my first experience using a sub-woofer. First, the tension bracing inside the back chamber had to be shaved for the 18" driver to fit properly. The amp arrived today, but w/o proper bass eq. Without eq, the sub system is not full-range, down to 20Hz. But does it really matter for music? Since the midrange drivers and horn haven't arrived yet, I am using the sub with my Circe speakers. My quick and dirty impression - small crossover and level adjustments have a large affect on sound. This will take some effort to optimize. Also, the mis-matched Welborne DRDs amps and Alon Circe speakers work better with sub reinforcement. It is 2:00am now, so it's time to get some sleep!

System edited: Bruce Edgar called today. Finally, he is testing the Vitavox S2 driver integration with the rest of the system. Initial results are looking good. He described the S2 as sounding very different from the stock JBL 2441 drivers, being sweeter and smoother. This is just what I wanted! I asked him to continue evaluation, testing the limits of performance on large-scale symphony music, and other demanding material. After many months, there is light at the end of the tunnel!

System edited: The Seismic Sub shell arrived yesterday. It ships in three separate pieces, so moving is easier than expected. Bruce is sweeping the 18" JBL driver, and plans to ship driver and Hsu plate amp this week. Also, I removed a free standing wood-burning fireplace from the listening room to make room for the sub. Bruce explained the tiled floor beneath the fireplace will provide an excellent boundary for the LF exhaust to enter the room.

System edited: The Edgar Seismic sub is scheduled to be delivered later this week. I decided to remove a wood burning stove to make room for this huge sub-woofer. The floor beneath the stove is ceramic tile, which will provide a boundary and reinforcement for the downward firing low freqs. The 80 Hz straight horns arrived a couple of weeks ago. Bruce is working on throat adapters for the Vitavox S2 midrange drivers. Fane ST5022 HF tweeters are purchased. My girlfriend thinks I'm nuts, but I know that she will be pleased after she listens to these horns.

Artg, Thanks for your comments! The Lamm works well for me. It has some issues - mostly some dynamic compression, upwards tonal balance, and two big chassis. These issues are balanced by super-precise spatial benefits. Positioning and sense of space are awesome! The Circes are my second Alon speakers. My first were Alon IIs purchased new in 1993. And I never feel the need to upgrade my little Meitner after listening to the Big Boys (DCS, EMM Labs, Lavry, Audio Aero, etc). It may not be the SOTA, but it's not embarrased either - it's a keeper...

System edited: My Museatex Bitstream returned today after servicing by John Wright. The data connection was randomly dropping signal due to a loose connection, so I sent the unit to John for repair. While it was in the shop, John replaced some of the caps with Black Gates. My Bitstream was already modified to Data II status, and for my ears, it was essential for digital playback. It really "vinalyzed" music. I really missed it! Just put it back into my system this afternoon, so I will withhold judgement until after break-in. My main concern is the BG caps do not screw-up the beautiful "rightness" of the DAC.
