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!

Skushino,

I think you and I share similar objectives, but have arrived at a comfort zone audio wise using different means, with different levels of achievement, with your system being closer to our set goals.

I'm very happy where my system has gotten me, so I know your listening must be very special for you. Congratulations.

I read you hail from Seattle, I am relatively close, on the north end of Whidbey Island. I take it you also know Mike Lavigne, and perhaps you are also a member of the PNWAS. Mike was kind enough to have me over a few years ago.

Best regards,
Dan

System edited: I'm of the opinion that the bass is one of the most critical and most challenging parts of playback. Not talking about quantity, but rather the quality of bass reproduction. My approach has been to split the bass in two parts - Low and mid bass covered by Danley's SPUD tapped horn (< 90 Hz), and upper bass / lower mid served by a 140 Hz tractrix horn (between 100 Hz - 800 Hz). This approach is satisfactory, but I believe there's room for improvement by adding a dedicated mid bass channel to cover ~ 50 Hz - 250 Hz. I'm finally preparing for my next project, a pair of mid bass horns. Why tackle the effort of building a huge pair of horns rather than a different solution? I chose horn loading to match the sensitivity of the other channels. But most significantly, bass reproduced by an 'adequately large' horn is unique compared to other solutions. Listen to cellos, standup bass, tenor / barry sax, or piano on a big horn like Tannoy Autographs or Klipschorns horns and you might agree. One of many challenges is making a horn work in an average-sized residential listening room. A straight horn is not an option due to size considerations. BLHs can sound fine but have freq response irregularities. I've decided to build a folded horn based on the University Dean. The drivers are C-15W dual-impedance woofers with huge alnico motors. I hope to have them finished in time for the holidays.

System edited: Added Peerless 4611 / Western Electric 618-B SUTs to system. Wonderful sound. In comparison with the Bent Audio / S&B TX-103 silver coppper, these are equally warm and clear, with a touch of 'vintage' feel.

System edited: Have been experiencing a vinyl / LP frenzy this summer. Spending more time in record stores, in the jazz, blues, and classical bins. Also hit the lottery when a friend in the pro sound industry very generously gifted me a pair of Peerless 4611-8 transformers from an old mixing console. Found very little information online, other than they seem to be WE 618B equivalents. They're serving duty as SUTs now, between the Ortofon SPU 85th Anniversary and.... Also added a Wright Sound WPP-100 vacuum tube phono amp. Separate PS with a respectable PS transformer, separate Cu chassis / farady cage for signal circuit. I've had a long-time fascination with this unit, so bought one as an experiment. It lacks the frequency extension of my modified EAR, but it is more engaging to my ears (pun intended).

@Babybear - A local audiophile friend owns the Audio Desk RCM. I think he may also be auditioning the KL Audio, so would expect some feedback in the near future. Check under Mike Lavign's system thread.

Things I like about the KL Audio RCM:

1) cleans records effectively, with no contact. they look new after cleaning. even the used record store finds

2) ease of operation. simply insert the LP in the top of the machine. that's all. no special cleaning solutions needed, other than distilled water. 6 minute cycle to both clean and vacuum dry the LP. the machine even softly 'beeps' every couple minutes if an LP is left in the machine after cleaning, as a reminder.

3) construction. the machine appears to be very sturdy, with thick metal plates forming the chassis. only time will tell, but this machine appears over-built for the task.

4) industrial design. a subjective matter, but it works well for me. I would describe the style as tasteful contemporary industrial. it should fly by the WAF test.

5) size. the footprint is minimal. I'm traveling away from home this week, otherwise I would measure the dimensions and post.

Things I like less about this RCM:

1) drying cycle noise. the machine uses an internal vacuum to dry the record. it is much quieter than my old VPI, but it is still a vacuum machine. I would describe the noise level as quieter than most RCMs, but not quiet enough to clean records in the same room while listening to music.

2) price. I don't remember the price of the Audio Desk, but I believe this machine is less expensive. Still, several thousand dollars to clean records is an investment.

Very Interesting about the KL Audio RCM. How do you think it compares both in terms of build quality and performance to the Audio Desk Ultrasonic RCM?
Thanks,
Arnie

Have been using a KL Audio ultrasound record cleaning machine for the past month and a half. It is one of the most pleasant pieces of audio gear I own. No contact and fully automatic, insert the LP in the top, like bread in to a toaster, and that's all. The machine automatically turns on, cleans, and drys. Built like a tank. It's actually fun (well almost) to clean LPs now. I believe this is a best in class machine. I've owned or been exposed to VPI, Nitty Gritty, Loricraft, Audio Desk, etc. Records appear new after cleaning.

Sony SCD-1 repair:
The sliding tray door was making grinding noises, and Redbook CDs were not reading properly. Replaced two motors and lubed the transport rails. The unit is 100% functional again! Used as a transport feeding my Lavry and Bidat DACs, it sounds like coming home after using the Oppo for transport duty. Much better, refined, deeper and rounder bass, with subtle cues overlooked on the Oppo

Lavry DA-10 mod:
The Lavry shows extraordinary resolution, but also sounds too noisy and clinical. The power supply is a cheaply executed switching supply. My tech is building an outboard PS. Hope to retain the Lavry's resolution and gain a quieter, more polished sound.

After tracing and banishing some noise problems, the PurePower APS is filtering power for all my components other than the Crown K2. Besides the utility value of providing some electrical isolation and protection, the unit imparts a micro-texture / silkiness to the sound. I find this very welcome and endearing.

On a hunch I auditioned a Crown K2 amp in place of the Yamaha B-2 on my tapped horns. This was a staggering success! The uprated power (500 w/ch) and damping factor (>3,000) of the Crown paired with the big Danley sub horns lay down a carpet of solid bass. For subwoofer application, the Crown is a winner.

Have also been listening to some Peerless mic transformers wired for step-up duty. Very silky and sexy, I like these. Paired with the wrong phono amp, the sound could be too smooth. Paired with my 834P the sound is just right.

Hi Jason, yes, please drop me a note when you plan to visit Seattle and we'll make arrangements.

Happy listening!

skushino

Skushino,

Thank you for your generous invite. I will for sure come by and visit when i'm in the seattle area. I think you might have confused me with another fellow member as i've never used the Crown amplifiers but i've heard great things about them. Time aligning and crossing over all those drivers must be very difficult and time consuming. But from reading all the previous threads, you must have all that pretty much down pat. I also notice that your taste in musicality is very close to mine so i think i would enjoy your system very much. Hope to see you soon!

Jason.

Bmwmcab - My Avantgarde audition in Vancouver was many years ago. It would be a surprise if the dealer hasn't learned how to make his Avantgardes sing since my visit. I have a friend with the Uno, and he's very happy with them, although I haven't had the opportunity to hear them myself because he's in LA. I looked at your system pictures and you seem to have enough room to place your speakers well away from the front and side walls. I'm always surprised how much horns benefit by being away from the room boundaries.

On a different topic, I was researching power amps for my subs, and remember seeing your name in some discussions about the Crown K2. I don't see that amp in your system description. Wondering if you used the Crowns in the past, and if so, would be interested in your experience?

If you're in the Seattle region, you're welcome to come visit. You can PM or leave a message here.

skushino

I love the look of your horns. At first glance, i thought they were the avantgarde trios! I see that you've visited the avantgarde dealer in vancouver and found the sound not to your liking. I live in vancouver and also heard the set up and had the same findings as you. I own the avantgarde uno's and have set them up to my liking. I like to feel the emotion in the voices. It is not thin and lean at all compared to the dealers. I would love to hear your system as well as i see you live in the seattle area. I would love for you to come and listen to my system to change your perspective of the avantgardes as well.

You are really working on your System. Very interesting solutions. I made some modification with the ML2.1, I replaced the speaker binding posts (4/8/16ohm) with WBT silver posts and also the RCA input with WBT silver. A good amp jumped to the next sonic level with these simple changes.

I decided to try a simpler version for my system, using a Brenneman Cavalier Plus SE amp for the mids and HF, the Lamm ML-2 for the upper bass and lower mids, and Yamaha B2 for the Danley subs. bty, the Po Boys are wonderful...
