Elite Audio Brings Spiral Groove, Zesto, Kharma and more to BAAS Members

Over 50 BAAS members braved a rare San Francisco heat wave and Elite’s store renovations yesterday to hear some of the best that vinyl and tubes have to offer.

Thanks largely to the efforts of Michael Woods (our host) and Peter Truce (or Analog Czar and organizer), the event was a great success. Thanks also to Allen Perkins (Spiral) and George and Carolyn Counnas (Zesto) for sharing their knowledge and expertise. (As a special treat, Zesto played the prototype of their much-anticipated tube power amp.)

Well done!

Vinyl – “I’m Swimming in the Sound”

cd-lp

Q magazine features this article about a 20-year-old’s first experience listening to vinyl – LZ’s “Whole Lotta Love” no less.

Charming and hopeful. Wait until she hears DSD!  LOL.

It had to happen: First 3D-printed Record Albums

3dprintedrecord-660See this Wired article for a demo and an explanation by the engineer.

OK, so sound quality is about that achieved by Edison. But I predict that it’ll improve – a lot.

Is this the ultimate audiophile DAC?

Are “Record Players” Better-sounding?

OK, don’t shoot me over what you read…

Quora, a popular and high-quality opinions site, has this to say on the matter.

Something for everyone – or not.

Sample: “…audiophiles tend to prefer vinyl over compact discs for pretty much every genre of music except classical.”

WOW – The Craziest Record Ever?

For the vinyl person who has every thing – an LP consisting of one note.

That’s right, the whole record is a single pitch. 33.33 hz of course. But wait…you can play it at 45 RPM and get 45hz!

The price? 33.33 GBP of course.

Looks? 007-dapper.

Coolest Stereo Ever (If Apple Existed in 1961…)

Just lovely. Designed by the inimitable Dieter Rams, it featured a 6-tube amp and cord drive.

Affectionately called the “Snow White Coffin” by some. I wonder why….

Sonorus – Pure. Audiophile. Analog.

I’m a digital guy, buy I gotta say this is sexy. Recommended by Yarlung Records (which has released two hot-selling LPs and may release on tape). Get yours here. Note that they are coming out with amps and electrostats!

I will investigate for a BAAS event when the line is released.

The Cool Sound of Valves

Check out this article in IEEE Spectrum regarding why tubes sound better.

It’s a bit long, but its arguments are lucid and well-presented. Be sure to read the sidebars too!

Amazingly (for an IEEE pub), bothe the objective and subjective sides of the story are covered.

Also, note how many Bay Area people are on center-stage.

The money quote:

In spite of the bad press, high-end audio was estimated in a Wall Street Journal article in December 1991 to sell as much as $1 billion per year worldwide, enjoying a 20 percent annual growth rate. Japan, alone, consumes $200 million per year in high-end components.

DIY Tube Phonostage Class at the Randall Museum by Ed Yang

Some of you may know that once a year I teach a DIY tube gear class. This time I’m offering a phonostage / phono preamps class. You will lean about RIAA equalization circuits and build one of my designs known as The Randall Phono.

I have subjected Randall Phono to a number of shootouts / comparison and it has always come out on top. It has a big tone with superb midrange, sparkling treble and solid extended bass. The sound stage is big without being bloated. Imaging is spot on where you can easily pin point the location of performers and instruments in space. At $196.00 for the class, around $350.00 in parts and 8 class sessions you take home a phonostage that is truly high end.

The phonostage you will build is the “passive” type based on the 6SL7 family of tubes, 5V4 rectifier with selectable cartridge loading. This is a medium gain phonostage so you can use it straight with 2mv and greater cartridge. If you use a low output moving coil cartridge (LOMC) you will need to use a step-up transformer (SUT). With a good SUT this phonostage have enough gain to accommodate LOMC as low as 0.14mv. The output impedance is around 30K so it should be able to drive most preamps or integrated amps.

This class is recommended for intermediate or advanced students. If you have taken any of the previous Randall Tube Audio DIY classes or have experience soldering, you are good to go. Even if you have never soldered but have good dexterity, then this class could be ok for you but contact me first. The class is limited to 10 students. This will be the only time I’ll offer the class so don’t wait till the last minute to register.

The Tape Project and Focal Rock Bay Area Audiophiles

BAAS members got a special treat treat today, served up hot at 1340 Mission Studio in San Francisco.

Members coming out of the mastering room uniformly commented that they had just experienced the best sound that they had heard in a long time. I had to agree.

In my experience, this level of fidelity requires attention to all elements of the reproduction chain. In the case of today’s event, four elements stood out:

  • THE TAPE PROJECT SOURCE MATERIAL – Have you ever heard a master tape? We came about  as close as mere mortals can. We listened to direct dubs of the master, recorded on 1″ two-track media at 15 ips! Wow. Nothing quite like it. And I’m not sure that I ever heard an analog source this quiet.
  • SUPERB ELECTRONICS BY EAR and VTL – These premier brands need no introduction. Top-of-the-line line-level components designed by Tom deParavicini himself. And power from the mighty Siegfrieds.
  • FOCAL GRANDE UTOPIA LOUDSPEAKERS – About 7′ of pure linearity. The effortless bass was  striking to me. The smooth treble from a Be inverted dome was also quite moving. But the degree of driver integration was perhaps their most impressive quality. These huge multi-driver boxes sing with a single voice.
  • CUSTOM, PURPOSE-BUILT LISTENING ROOM. No parallel surfaces. Balanced use of absorption and diffraction. Ballast (mass) in key areas of the structure. A great showcase for sound.

Our hosts made a great event even better. Many thanks to Bob Hodas, Paul Stubblebine, Michael Romanowski, and Bea Manley. Your hospitality, expertise, and enthusiasm were terrific!

$1 Vinyl – Just Like the Old Days!

New DIY class next January

San Francisco audio designer, Edwin Yang, will be once again teaching a class starting in January, 2011 at the Randall Museum. For the last few years, Edwin has been teaching students how to build a tube linestage, myself included. The linestage, although not expensive, is a terrific piece of gear – I sold my other 2 tube linestages after building it.

The next project is a tube phono stage. This class will be more challenging than the linestage class, but still possible for the student that has confidence and some dexterity. It is not necessary to have built anything before but that it desirable.

The class will be for several Saturdays starting in January. Some will finish quickly while others, like myself, will take the total of 10 Saturdays to finish. The class is always entertaining and educational and I highly recommend it. Cost will be around $600 – $700.

Phono stage comparison at the Randall Museum October 9th

The Bay Area Tube Users Group will be hosting a phono stage comparison at 1pm on Saturday October 9th. I will be bringing my Nighthawk and Prism Orpheus to compare to Edwin’s phono stageIf you have a favorite phono stage you want to compare, please bring it along. So if you are on the fence as to whether it is worth the effort to build one, attend the event and decide for yourselves.

Must-see Movie for Vinyl-lovers

“To Have and to Hold” – as in LP (not book) – is an upcoming documentary film about the hold that vinyl has over music-lovers everywhere.

The film is still in production, but you can get a taste of it from this “teaser” video.

Great stuff. This film should build on Fremer’s work, raising awareness and entertaining all at once.

Spiral Groove Turntable Impresses Digital Audiophile(s)

BAAS membership reflects the current trends of audiophiles worldwide. As such, the majority (including myself) listen to digital these days. So it was interesting to see how our first “analog event” in several years would be received.

About 30 BAAS members gathered at Jason Victor Serinus’ home yesterday to listen to the latest in analog source technology, delivered by Allen Perkins of local manufacturer Spiral Groove (SG).

The system featured the following gear from SG:sg.jpg

  • Spiral Groove SG 2 Turntable ($15,000)
  • Spiral Groove SG Tonearm ($6,000)
  • Lyra Cartridge ($6,000)
  • Lehmann Audio Decade phono section ($2,400)
  • Spiral Groove preamplifier (projected $15,000)

An impressive array, to be sure!

I am quite familiar with Jason’s system and listening environment, at least for digital sources. Here are my impression of yesterday’s sights and sounds:

  • The SG gear is beautiful to look at, and even better to listen to. Furthermore, it’s practical. For example, it can be set up by one person in 30 minutes (!). Simple elegance.
  • All told, I listened to the system for five hours. I heard fewer than a dozen tics or pops. This is a new record for me <g>. Especially notable: not a single record was treated in any way during the event. No rituals – just load & play. (Sorta like a CD…) [One member told me that the sound was clean because only vintage older "virgin" vinyl was used.]
  • Allen’s description of the engineering design choices that guided him made a lot of sense to me.
  • The sound in the second session was a bit tighter than the first. (This is not unusual. I think it’s caused simply by the gear being more fully warmed up.)
  • Nordost Odin cables are the real deal. At one point we substituted the preamp’s power cable with a Odin. Wow.
  • For the first time in a very long while, I was thinking “…maybe I do need a turntable…”

We also conducted several listening tests on digital sources. These allowed us to compare several digital exemplars to state-of-the-art analog. I’ll say here that two things were apparent:

  • Analog rocks. There’s a reason why so many audiophiles are driven to turntables (see this article from today’s NYT). – they can sound great!
  • PS Audio’s(PSA’s) new “Perfect Wave” stack combines outstanding ease-of-use with media flexibility and great sonics. That’s a tough combo to beat! Very nice kit, especially for audiophiles wishing to get into high-resolution without going to a computer. (Digital sources that I consider “reference quality” generally have price tags beginning at 2X the PSA tariff.)
  • I preferred the sound of the Wavelength Wavelink USB audio interface to that of the the transport (many members agreed). I don’t think it yet matches the best in firewire converters, but it sounded quite detailed and transparent to me (especially on hires material).

Note that Jason’s description of the event – and activities leading up to it – can be found on the Home secrets Blog.
