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!

wow - love it! I've always been intrigued by the Lamm preamp, but im afraid it's a bit out of my price range. Looks darn good in your system though. Im also a HUGE fan of Alon and Meitner gear. You have very fine taste in gear, my friend!

I'm spending alot of time on the phone with Bruce Edgar. Super guy to work with. Yesterday, I reevaluated using the sealed-box sub, and am now leaning more towards the horn loaded Seismic Sub. Haven't quite figuerd out how to fit it into my room. Minor detail... This hobby is going to be the end of me!

System edited: With the addition of the Welborne SETs, the system is in-between where it once was and where it's going. It was a high-power, conventional speaker set-up. Only now, the 8w Welborne amps have replaced the former amplifier. The result is a very nice midrange and HF, with wonderful harmonic texture and contrast. Surprisingly, the SETs are also much quieter in terms of hiss, hum and other extraneous noise. On the other hand, bass suffers, with loss of definition and power. There is simply insufficient power to driver the Circes. Over the past months, I have been gathering the components to build Edgarhorns. The project is now a priority, to regain system matching with the low-powered amps. So far, I have a pair of EV-M15L 15" upper-bass drivers, a pair of Vitavox S2 midrange compression drivers, and last week took delivery of the 80Hz bass horns. Practicality is forcing me to go with the sealed-box sub-woofer solution, rather than the amazing Seismic Sub. I just can't find the space for a refrigerator-sized sub-horn in my room... This is a compromise that I'm making very reluctantly. But Bruce assures me that the smaller sealed-box sub will perform satisfactorily, if not to the same level as the huge Seismic. The Vitavox drivers were sent to Bruce for evaluation and fitting to custom 350Hz horns, as the drivers are different from the JBL 2441s he specs. Also, my German cabinetmaker just left for a one month vacation back home, so I have to exercise patience until he returns. My expectations for the project are fun and learning, and I've decide to post my progress here, sort-of as project documentation, or diary.

Owen, just checked in and saw your comments. Would love to speak with you further about your phono stage. I'll need another for my second tonearm/cartridge. Other than the Lamm, have you listened to other units? I'll phone you to learn more. Thanks for the input.

I'm a little late on the response, you can email me if you want more info, but Nick Doshi has created a masterpiece with his X phono stage, in fact it spanked badly a Lamm LP2 in direct comparison. The Lamm sounded somewhat artificial where the Doshi was organic with just center of the earth bass and dynamics, larger soundstage and more differentiation of instrumental timbres and detail. The LP2 was sterile in comparison, overly smooth, though it was very "quiet". The Doshi just had tremendous energy and power behind it that is just at a completely different level

System edited: Another experiment - Added a pair of 8w/ch 300B SET amps to the system this weekend. This is part one of my move to a low-power high-efficiency system. Since I do not have high-efficiency speakers (yet), I am using my current low-sensitivty (87db/w/1 m). Still forming impressions on this change. Most obviously, this amp / speaker combination should NOT work whatsoever. The speakers are low sensitivty with complex crossovers - definitely not a good match for a SET cricuit. My expectations were low to none. But surprise... The combo produces sound, even some music. The biggest surprise is the pretty loud SPLs produced. Not surprisingly, the freq extremes are rolled off. But the midrange that remains is really pleasing. Especially on stringed instruments and vocals, there is so much harmonic texture and resolution. Piano lacks the lower fundamental tones. All in all, better results than expected. Now, I just need to get cracking on the horn speakers!

Thanks for your input, Randy. Our listening rooms have similar dimensions. I agree that speaker positioning is critical with Circes. More so than any speakers I owned before, and there were a few: Alon Model II, Apogee Duettas, Vandersteen 2C and Klipsch Heresy. But, I am also a more critical listener now than before.

In any case, the current set-up is the best I have attained in my room for soundstage width and image depth. They were positioned all around the room, at one time or another. Using Cardas as a guide, the distance of the speakers from the front wall also is very close to a third of the length of my listening room. There was a pronounced mid-base resonance before, that was tamed with this lates position. I think they will remain here for awhile. As you know, the Circes are pretty hefty...

The Counterpoint is almost 20 years old, and was used to drive all my speakers, even the Apogees, with grace. It's still breezing along, no problem...

skushino

So you have your Circe's roughly 7 feet apart? That's about the same configuration that I have in a 14 x 20 room, except that the Circe's are along the long wall. Each speaker is very slightly toed in. They are about 5 feet from the back wall (measured to the front of the cabinet). Right now, the sound I am getting from the Circe's is really breathtaking. It's only taken me 3 years to acheive this kind of sound, with power cord and interconnect upgrades and tweaking of the setup. I thought when I switched from the CLS's to the Circe's that the latter would be easy to setup. Boy was I wrong.

Looks like you have an excellent system. I bet that the Counterpoint amps must mate really well with the Circe's. I run mine with Audio Research Classic 120's. Althought that combination works really well, sometimes I wonder if a little extra power is in order.

It's great to see someone else taking pains to make these speakers really sing as they are capable of.

System edited: Last week I changed speaker positions, based upon Cardas' method. Now they are located 6'10" from the front wall and 4' from each side wall in my roughly 15' X 18' listening room. Listening position is equidistant from the speakers, forming an equilateral triangle for nearfield listening. Compared to the old positions (speakers not as far into the room), a resonant base node is better controlled and imaging depth has substantially improved. Next, I want to measure room response with ETF or another suitable tool, for final calibration.

Owen,

Nice to hear from you. The Venustas is a cable that I am becoming vey familiar with the past year. I like it. It seems to do the job of transferring signals w/o too much damage, in a natural manner.

When you have a moment, I would like to learn more about your "special" phono stage.

Mike, glad to hear from you, and it was a pleasure being a guest at your home. No, I can't take comfort in your misfortune, but I'm not surprised to learn that this happened to others. Analog is a very delicate hobby!

skushino

Scott,

Looks like things are coming together for you nicely. Thanks for posting your system up here. How do you like the Venustas cabling by the way?

Scott; if it helps at all....'be there, done that'.

the day i first got my Sirius III, i was so excited i allowed the vdH Colibri to slide off the edge of the lead-in groove (the platter and arm were not fully level).....this slightly bent the caneliver.....i tried to 'nudge' it back.....SNAP!! went the canteliver.

not very much fun.

i hope my (very expensive) tale of woe brings a little comfort.

System edited: Last night I was listening to music and enjoying a glass or three of wine. Feeling good, I had the brilliant idea of calibrating my TT. In the process, I accidently brushed the tonearm while the cartridge was on the Shure scale, and severely bent the cantilever. The cartridge is toast... Moral of the story: adjusting TTs and enjoying a glass of wine mix like Michael Moore and the GWB. At least it was the Denon and not the Shelter.

Thank you, Mike. I try to remember that our hobby is often more about the journey rather than arriving at the destination, although your case may be an exception!

It has been fun gaining exposure to new gear, but the greatest pleasure has been discovering new music on a system that allows me and my friends to enjoy it.

I'm looking forward to visiting your "barn" soon. Also looking forward to hosting you.

scott

skushino

Scott; Congrats on your very well thought out listening goals.....clearly a result of much consideration. the gear you have assembled should get you very close to your target.....excellent choices of components that all share naturalness and lack of 'hifi' sound. we share listening philosphies.

maybe soon i'll be able to hear it.

it has to sound great.
