Vandersteen Audio Treo loudspeaker Page 2

The Vandersteen Treo was noticeably insensitive compared with the 85dB-sensitive KEF LS50 that preceded it in my room; I recommend at least a 100Wpc amplifier to drive it. The benefit of a truly time-coincident speaker is that a pair can give superb stereo imaging. That benefit is sometimes offset by compromises in dispersion, but the close-as-practicable vertical spacing of the Treo's drive-units means that it's not as fussy about the exact listening axis as might be expected. However, you still need to sit with your ears close to the optimal listening axis. Pink noise revealed a hollow quality that developed when my ears were higher than the midrange unit's dustcap. The front and rear cones, which provide ground clearance for the downward-firing port, can be adjusted to tilt the Treo back a little, to ensure that the speaker's owner gets the combination of clarity and neutrality paid for.

And that clarity was impressive. These days, I listen to NPR mostly via the Internet, using my Logitech Transporter. The Treos laid bare the data-reduction artifacts in live feeds from reporters, the various gurgling and "underwater" sounds that presumably stem from stacked lossy codecs. Similarly, the differences between the "Red Book" and 24-bit/96kHz versions of Paul Simon's "Getting Ready for Christmas Day" (Apple Lossless files ripped from CD, and transcoded from HDtracks FLAC downloads, respectively), which had proved fairly subtle with this overcompressed production through the Sony SS-AR2 and KEF LS50 speakers, were readily audible with the Treos. The hi-rez version offered a little more space between instruments, a little better decoding of soundstaging cues. The improvement made to my system's overall sound by the BSG Qøl Signal Completion Stage, which I reviewed in February, was unambiguous with Treos in the system.

The 1/3-octave warble tones on Editor's Choice (CD, Stereophile STPH016-2) were a little suppressed in the 100 and 80Hz bands. Jerome Harris's acoustic bass guitar on Rendezvous (CD, Stereophile STPH013-2) therefore sounded a little reticent. However, the tones were strongly reproduced, with negligible distortion, from 63Hz down to the 32Hz band, the latter aided by the lowest-frequency mode in my room. The higher-frequency warble tones on Editor's Choice uncovered some liveliness just below middle C and between 500 and 600Hz on the cabinet sidewalls, which added a very slight boxiness to the sound of Richard Lehnert's speaking voice in the "Channel Identification" and "Channel Phasing" tracks on this CD, but the Treo was otherwise lacking in noticeable coloration. Both the sound of John Barrow's solo baritone and that of the Choir of Guildford Cathedral, in Vaughan Williams's Fantasia on Christmas Carols conducted by Barry Rose (CD, EMI Classics CDM 5 67427-2), were produced with natural tonal colors and no trace of hardness, despite the recording's 1966 pedigree.

The half-step–spaced low-frequency tonebursts on Editor's Choice were reproduced with good articulation, but with greater weight to the region below 80Hz than I was expecting. The combination of the integral subwoofer and the downward-firing port endows the Treo with almost full-range bass extension, which is commendable at its price. Steven Stills's bass guitar in "Suite: Judy Blue Eyes," from Crosby, Stills & Nash (Apple Lossless file transcoded from 24/96 FLAC download, HDtracks), was reproduced with a superb purr to its lowest registers—particularly the note A (55Hz), which coincides with the peak of the region covered by the Treo's subwoofer—with relatively good definition for a reflex design. The Treo's rather exaggerated lowest register still allowed Leonard Cohen's grumpy, mike-swallowing baritone in "Going Home"—"I love to speak with Leonard, / he's a sportsman and a shepherd, / he's a lazy bastard in a suit"— from Old Ideas (CD, Columbia 8697-98671-2), to emerge unscathed from the woofers, though the lowest notes of the tuba-toned bass guitar in "Amen" sounded rather lumpy.

My longtime test for bass articulation is the repeated 16th-note bass line in "Last Train Home," from Pat Metheny's Still Life (Talking) (CD, Geffen GEFD 24145-2). This is a difficult track for reflex-loaded speakers to correctly reproduce. The higher the Q (Quality factor) of the low-frequency alignment, the more the bass notes run into one another. The Treos did relatively well with this track, preserving the onset of each bass note with only a slight smearing of the following tone. The doubling of Carol Kaye's bass guitar played with a pick with a double bass in "Sloop John B," from the Beach Boys' Pet Sounds (Apple Lossless file transcoded from 24/192 FLAC download, HDtracks) had superb clarity, as did the bass guitar and kick drum in lock step in "Hey Nineteen," from Steely Dan's Gaucho (24/96 Apple Lossless file ripped from DVD-A, Warner Bros. 7102151014-2-2).

One of the Christmas presents I gave myself last year was the 24/48 download of Led Zeppelin's Celebration Day, from the band's 2007 tribute concert for Ahmet Etregun (HDtracks). I listened to this album a lot through the Treos over the Christmas weekend, and unfortunately the Vandersteens laid bare the fact that the sound quality is not what I was hoping for. Yes, Jason Bonham's drumming channels his father's very effectively, and John Paul Jones's use of a 16' stop on the Hammond bass lines and an equally phat tone on his bass guitar does add magnificence. But overall, the sound isn't close to the 1972 board mixes of How the West Was Won (24/48 Apple Lossless files ripped from DVD-A, Atlantic 83587-9), lacking openness and natural tonal colors, even with electric and electronic instruments. When I compared the drum and guitar sounds and the space around the snare drum in "Since I've Been Loving You" on both Celebration Day and How the West Was Won, the Vandersteen speakers revealed the 40-year-old recording to preserve the sounds of real instruments rather than presenting them as shaped, textured, and processed noises. An interview with the new album's mix engineer, Alan Moulder, in the January 2013 issue of Sound On Sound, provided an object lesson in how modern technology can be misused to screw things up. Had Moulder monitored his efforts with speakers as revealing and uncolored as the Vandersteen Treos, he might not have used such a heavy hand on the Pro Tools plug-ins and processors!

The Treos threw a stable and accurately defined soundstage, though the top octave was presented a little more forward in that stage than the lower frequencies. For example, the inevitable ticks of the needle drops I am regularly making now that I've bought the sample of Ayre Acoustics' QA-9 A/D converter, which I reviewed last November, stand clear of the body on the instrumental tone. I have loved David Abel's performance of Beethoven's Violin Sonata in G, Op.96, since it was released on David Wilson's label in 1984 (LP, Wilson Audiophile W-8722). I thought I had eliminated all the major ticks when I did the transfer to 24/192 digital back when I was reviewing the KEF LS50 speakers last December. But the Treos uncovered more ticks that had been lurking in hiding. Still, the tones of both Abel's Guarneri violin and accompanist Julie Steinberg's 9' Hamburg Steinway were uncolored and lifelike.

With its lack of midrange coloration, its transparency, and its extended lows, the Vandersteen Treo proved adept at faithfully reproducing solo-piano recordings. Following Michael Lavorgna's turn-of-the-year recommendation on AudioStream.com, I downloaded from HDtracks the 24/192 FLAC files of David Chesky's new album, The New York Rags, one of Chesky Records' new Binaural+ Series. Played back via the USB2.0 input of the excellent Arcam D33 processor, the transcoded AIFF files of this suite of 18 energetic compositions for solo piano sounded almost real. (The quote from "Tiger Rag" in Chesky's Rag No.14, "Kids You're Late for School Rag," is a delicious contrast with the frenetic modernism of much of the rest of the writing.) The illusion of reality was helped by the fact that the piano, a Yamaha DCFX Mark IV Disklavier Pro concert grand, had been recorded with the B&K 4100 Head and Torso simulator using Crystal cables to feed the MSB A/D converter that had so impressed Michael Fremer (see "Analog Corner" in this issue), then processed using the BACCH technology developed by Professor Edgar Choueiri, of Princeton University's 3D Audio and Applied Acoustics Lab, to render the binaural recording compatible with playback through loudspeakers.

The perspective of Chesky's recording is from fairly close to the piano, and the Yamaha's tone is fairly homogenous compared both with Julie Steinberg's Steinway and the 9' Steinway on which Robert Silverman performed Schumann's études Symphoniques and Brahms's Variations and Fugue on a Theme of Händel, which I mastered for release this spring as a Stereophile CD while writing this review. The decay of notes on the Steinway is more complex than in the Yamaha, a difference effortlessly revealed by the Vandersteen speakers. The Treos also did a great job of presenting Silverman's Steinway within the supportive acoustic of Sauder Concert Hall, at Goshen College in Indiana, to give a wetter sound, but one just as realistic as on the Chesky and Wilson recordings.

Summing Up
Looking back at my listening impressions, I see that I've pulled the usual reviewer trick of describing the individual aspects of the Treo's sound, the assumption being that when added together, they will fully characterize the speaker's quality. Not that that's untrue, but what I didn't mention at all is that the whole of the Treo's performance is more than the sum of those parts. There was never a recording that I didn't enjoy through these speakers, though with some overcooked modern recordings, that required some care in setting the playback level so that the sonic crap revealed by the Vandersteens didn't get in the way of the music.

For not much more than twice the price of the current version of his Model 2, Richard Vandersteen has, in the Treo, designed a speaker that fully justifies the dollar differential. Highly recommended.

I noticed more details about the brand of cables used than the brand of drivers used in this "highly recommended" 85dB/w/m shhhpeaker.

That information is a few clicks away on the Vandersteen website. I applaud reviewers who don't waste space recounting spec sheets and marketing literature. Providing a link is more than enough.

I have not heard the Treo yet, but the Model 2 Sig turned me into an audiophile. I still clearly remember the day I demoed it 15 years ago. I had no idea that there was such a big difference between speakers or that "inexpensive" speakers could sound that good. It literally brought tears to my eyes when I listened to A Tribute to Jack Johnson in the show room.

(My username is because I'm a fan. I have no link to the company.)

The type, yes, BUT not the brand of drivers.

custom and semi-custom

At least some of the drivers are custom or semi-custom and I believe Vandersteen works with Scanspeak (and perhaps others) to create and modify drivers.

Thiel?

When I first saw the picture I assumed it was a reprint of an old Thiel review from 20 years ago. These really remind me of the old Thiels.

MY NEW STANDARD

I have been looking for the perfect loudspeaker for over 30 years.

I started with some Polk RTA 12 Monitor speakers, then went to Vandersteen 2Ci speakers, then Vandersteen 3 and 3A speakers.

I have gone to hi-fi stores and the CES in Las Vegas untold times looking for something that cost under $10,000 and would be the holy grail; the one that really could come close to flawless reproduction of the live sound, but never could find it. 

I heard many excellent speakers, but for me there was always one major flaw of some sort that made them imperfect and overall not equal to my Vandersteen 3A speakers.

I finally became convinced that the Vandersteen Treo would be, if not perfect, an improvement over my 3A speakers that was worthwhile, so I bought a pair.

When I actually hooked them up in my home, I was awe-struck. These are not only much much better than my 3A speakers, they come as close as anything I have ever experienced to being a flawless perfect reproducer of the live musical experience. 

I have never heard a speaker that comes so close to perfection, without one single sonic flaw that I can identify in playing classical, jazz, vocal, bluegrass...you name it and it makes it come to life.

My NHT subwoofer adds some bass power and bass extension to the extreme low end, but the Treo is quite capable of very good bass performance on its own. For 80% of my music, the subwoofer is really not needed.

But as far as audible sonic flaws, I can find NONE!! That is a totally new experience for me.

My wife, who was not real convinced that any speaker could be worth $6000, and was more than ready to find some flaws she could criticize, listened for a couple of minutes and got a silly smile on her face and said not a word. She is in love with them. Wife approval factor; off the chart.

These speakers have totally redefined my concept of what ANY speaker is capable of, especially for less than $10,000.

A QUESTION

Vandersteen, in his owner's manual and product literature, makes a BIG point of his assertion that these speakers WILL NOT perform at their full potential unless they are bi-wired.

John clearly did not bi-wire the speakers when he tested them.

That seems odd to me and I wonder why he did not go with the manufacturer's recommendation. Surely he has access to some high-quality bi-wire cable sets.

With my Vandersteen 3A speakers and now with my Treo speakers I use eight lengths of Belden #10 102-strand wire with Audioquest gold-plated spade lugs to bi-wire them, and the result is superior sound quality.

Grills on or off?

I don't quite understand JA's statement in the review about the grills being mandatory due to baffle reflections:

"Each of the three upper drive-units stands proud of the baffle on a small subchassis; the grille's frame surrounds each of the diaphragms with a smooth surface to optimize diffraction and minimize reflections of the high frequencies from the baffle edges. Use of the grille is mandatory, therefore"

Is he saying that he listened with and without and determined this (because it doesn't sound like it). If not, has anyone heard them with/without the grills and reached their own conclusions? A lot of manufacturers claim their speakers sound great with the grills on, but it's rare for them to be right in all respects. There are bound to be trade offs with either scenario, rather than across-the-board improvements.

I thought the text of mine that you quoted self-explanatory. Unlike most speakers but like some of the Paradigms, the Treo's grille is an extension of the baffle and provides an essential part of the acoustic loading of the upper-frequency drive-units. The speaker sounds and measures worse without the grille.

Ah, thanks! That was, indeed,

Ah, thanks! That was, indeed, more explanatory! I also looked more closely at some pictures and the baffle-extending aspect makes sense.
