Description

My main audio system and conceptual approach to sound-staging, transparency and tonal balance have remained essentially unchanged since its assembly began in 1975.

I first heard KLH-9 electrostats at the home of a high school friend in 1970. Her stepfather, Dr. Byron Wise, was a botany professor at Memphis State Univ. and he had bought them at Opus 2 Audio. I had never heard anything as glorious, and swore I'd some day have a pair. The bulk of the Marantz tubed gear (including the Model 10B tuner) was bought from its original owner, a former pathology professor, Dr. Leonard B. Victor in 1975. Dr. Victor mentioned that he had purchased the gear in the early 1960s at "fair trade" (full price) costs, and suggested that I "might want to take good care of the equipment" as it might some day "be worth something". I am grateful for his stimulating my interests in vintage audio. Interestingly, at the time of the deal, Dr. Victor gave me a DECCA C4E cartridge, mentioning that he especially loved it for pipe organ recordings. Maybe I'll dig it out some day and see if it's as good as he claimed.

More recently, I added an additional amplifier and a pair of speakers to playback 3 channel SACDs (e.g. RCA, Mercury) and other multichannel SACDs. [as many know, these SACDs are copies taken from the original master tapes recorded on either 1/2" triple track AMPEXs (300-3) in the case of RCA, and likewise for Mercury (in some cases 3 channel 35mm magnetic film). Given the 30+ year lovefest that many of us audiophiles have had with the recordings from the "Golden Age", I just had to have some notion as to what Lewis Layton and the Fines must have heard prior to mixdowns. (However, it's probable that this material was never intended for 3 channel playback.)

I would be very interested to hear from others who have experience with reproducing the 3 channel RCAs and Mercurys as I have done. I have not heard any of the recently released SACDs of RCA materials from Chad Kassem's company, however a reviewer has claimed that the sound is superior to any prior SACD efforts. Given that the RCA releases were transferred by an exceptionally talented engineer at Soundmirror, I find that a bit curious. Of course, he was referring to two channel material, whereas I have been listening mostly to 3 channel versions (where applicable).

An Ampex 351-2 tape machine is my longtime favorite analog source and this unit was purchased from Wally Heider in 1981, and rebuilt by David Dintenfass (Full-Track Productions, Seattle, WA) in 2000. I recently rebuilt a triple pair array of KLH-9 full-range electrostats (two pairs of which originally were purchased ca. 1962, by Ewing Nunn of Audiophile Records, Saukville, WI), with the much-appreciated advice of David Janszen (Janszen Loudspeaker Co., Columbus, OH) and Russ Knott (ESL Repair, Chardon, OH). I undertook the project myself. It was extremely labor-intensive, so I don't recommend it as a DIY project unless you have loads of time and patience. (It can also be a dangerous undertaking as the signal voltages applied to the stator plates while music is playing are high!) The Marantz Model One Audio Consolettes, Model 7 preamp and Model 9 amplifiers were restored in 2010, with NOS parts through the Audio Connection (Seattle, WA). The Marantz 10B tuner was restored by Tom Cadawas (Cadawas Audio, Long Island, NY) in 1992, and has functioned flawlessly since (knock on wood!).

Obviously some of this equipment is now quite old as high end gear goes, however it has been restored to at least its original specifications. This is especially critical for KLH-9s as unless repaired/rebuilt at some point, they almost certainly will have one or more defective drivers (there are ten bass units and one tweeter per panel). Although less likely, they may have issues with the power supply (ei. reduced polarizing voltages). But when fully functional, they touch on majesty, and there's a good reason that HP loved them dearly (and probably still does).

My interconnects between the preamp and power amps (about 25' long) are made using Mogami Neglex (starquad) microphone cable. And it works quite well too. The speaker cables are 12 AWG copper, neoprene rubber power cables (USA made). A walnut stereo console was custom built for Nicholson's Audio (Nashville, TN) in 1962. The dimension of our music room is approx. 20' X 25' X 8.5', and the system is served by two dedicated 20A circuits.

I've had a near life-long love of analog tape, and am also really impressed with what i'm hearing in SACDs. I think the RCA and Mercury 3 channel SACDs are very interesting, and having recently added a pair of surround channels, am quite surprised at what I'm hearing. Of course, this latter topic of multichannel reproduction is quite a discussion all in itself! I just wish there was far more homogeneity with regard to how the various channels were used, relative volume levels, etc., as well as sonic quality.

Albert,
I'm sure those Bozak Concert Grands must have been mighty impressive!! I think the biggest thing I ever had was a pair of EV Patrician 800s from about 1975-78 (as an undergrad in Knoxville, I had heard a pair at a professor's home). Talk about efficient! (And colored too!) For something like that, one really needs a castle. Sounds like you were handling some really nice gear. Where was your store? The KLH-9 dealer in Memphis (where I grew up) was "Opus 2 Audio Salon", and I suspect that they must have sold quite a few pairs. They were the local Marantz, Audio Research, Thorens, Revox, Magenplanar, Crown, etc dealer, whereas their arch competitor, "Modern Music" sold Klipsch, MacIntosh, JBL, etc. There was a good deal of audio snobbery, with each store (both now just fading memories), claiming to cater to a different and more musically-informed, hence superior clientele. Ah, those were the days. BTW, I noticed you listen to the big Focals. I'm sure your system must sound as outrageously good as it appears! I recall a room at the RFAM in 2011, that had them (I believe) driven by Series 7 electronics, playing an LP of "Into the Labyrinthe". Astonishing! I had to pry myself out of my seat! philip

Dear Albert,
Many thanks! Your compliment means a lot!
Funny thing is that speaking of Sound Lab, is that I actually have Roger West to thank for my getting the KLH-9s. I had just moved to Salt Lake City in 1978, for a internship in pediatrics, and heard that a guy was selling LPs out of his home. Somehow I called Roger to get Bill Goldsmith's name. Bill was a longtime, hard core audiophile from Baltimore (he had and I bought from him all the early issues of STEREOPHILE and TAS) who had a business called "Discriminator Music". From Bill I bought a double pair of KLH-9s. I had them for many years, and eventually traced them back to Ewing Nunn (system shown on the cover of AUDIO in the 1960s). I must have moved these speakers across the country many times, and finally rebuilt them when I took early retirement in 2010. I love them, and have never claimed they're the best, but they are VERY musical and very addictive. Just like Harry always said the Marantz 9s are addictive. It's the same idea.
Kind regards, Phillip

Hi, and many thanks. Yep it IS totally retro!! But not the sound. And that's one thing I love about it. My work entails making high resolution (96/24) location recordings of orchestras, symphonic bands and choral groups in the Seattle area. Once I have mixed and edited the material, it is very helpful to have a full range, planar radiator system in order to hear the total impact (stereo soundstage) of what I did (be it good or bad!).

There is often a tremendous gap between "audiophiles" and audio/recording engineers, which I find intriguing and, in itself, would be an interesting topic. Suffice it to say that I know several guys in the Seattle area with extreme high end systems costing at least 10X-20X (and MUCH more than) what I've invested. And they have not heard my system, nor would they in many instances be willing to, or the least bit interested. Their loss! But let's face it, Saul Marantz (along with Sid Smith and Richard Sequerra), Arthur Janszen, Willi Studer, Stefan Kudelski, Georg Neumann, and Alexander M. Poniatoff DID know they what were doing. Let's not fool ourselves about that.

Hi Scott,

I hadn't checked Audiogon in ages. You're very kind. Was my great pleasure. And thanks for having me over. I still can't believe how uncolored your horn system is! And I was quite struck with its transparency. Will eagerly await your next rendition of those speakers. Kind regards, Phillip

Agree! A IV-S at 15ips NagraMaster is SOOO silky, and extraordinarily musical. I find it interesting that so many audiophiles are focused on the T (possibly to play 10" spools from the TP). But the IV-S is the REAL gem, at least for making recordings. Wonderful mike preamps, and one of the best limiters ever in the business. But I've largely moved to 96/24 due to cost (and quality-my last batch of Emtec is leaving small amounts of deposits on the heads) of tape, and the need to edit the recordings. My biggest project is the Seattle Wind Symphony. For our last concert we actually setup a DECCA tree (Neumann TLM50), an ORTF pair (TLM170R) and additional omni flankers (TLM50). We settled on a mix of the omni flankers and center tree mike (at -5dB), ALA Mercury as giving us the best sound at this venue. Let's face it, the Fines knew their art well.

Thanks, Sam.
A IV-S running at 15ips NagraMaster EQ is about as soothing and organic as one can ever hope for. But, tape is now about $1/min, and the last batch of RMG 911 I ordered is leaving residue, albeit a small amount on the heads. >>:)
But the real issue is what to do after the session. I'm mostly asked to do live concerts so there's almost always something that needs to be removed (e.g. coughs, dropped trumpet mute, clarinet squawk, etc.) or bad notes fixed (using material from sound checks and rehearsals) before compiling a CD. I had NOTHING digital in my home until 2000! But now I can't imagine not having it. So I master at 96/24. I think it's a reasonable compromise between the transparency and immediacy of high speed analog tape, and the other logistical and practical issues that have to be reckoned with in the the real world.

Thanks gents. Appreciate your comments very much. During the past year I've spent most of my time setting up a small oufit to undertake location recording in the Seattle area, employing various minimalist microphone methods. So i've spent less time with the system. But I've several local audio friends who heard my system and made suggestions, which I took. The changes that had the biggest impact were dumping the Cambridge Audio SACD player and getting an OPPO BDP95, and adding a PS Audio power regenerator. The effect of the latter was SOOOO incredible, I've not had any inclination to go back and re-listen without it! I ran two 20A lines to my music room, and the THD runs 4-6% with the PS Audio switched out. Switched in, it runs 0.4-0.5%. The biggest effect of cleaner power probably is on the Marantz preamp. It's been rebuilt with good tubes, but compared to modern day tube preamps, I'm sure its power supply is quite primitive.

Thanks, good question which I'll try to answer mostly in reference to the speakers. They sound as electrostats typcally do, and not radically different from any of several contemporary designs that I've heard lately. I mostly listen to various forms of classical, jazz and some pop vocals. They really excel with full scale symphonic works, also sources such as chorus and pipe organ, with say a Row F or G listening perspective. I guess if I had to pick one word to describe it, I'd say the sound is "lush", in a sense that the sound is enveloping and nicely recreates the ambient sound field, but is not particularly euphonic or colored. I think you'd likely have this situation with many dipole planar radiators having such a large surface area. Fortunately they don't seem to distort the image size of single instruments or voices, probably (in part) because they're oriented with their tweeters adjacent and placed at the centers of each double pair. I wouldn't say they have much in the way of what some readers refer to as "bass slam". But in the double pair arrays they have very deep bass that is well defined in terms of its pitch. Overall they're very transparent, and detailed, but not overly analytical in a way that (as many readers know) can become fatiguing pretty quickly.
