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.

Bravo for staying power. Most of us modern day philes struggle with constant equipment changes and lateral moves without true progress....

Regardless of how it sounds in absolute terms, this is one of the coolest systems I've seen. One of my friends has a pair of KLH 9's with a Marantz 7C preamp and 8B amp and it sounds quite good.

Cheers!

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.

Please give us a brief description of the sound !Must be sweet!!!

It's all real folks...I have been there and had seen and heard the system with my own two eyes and ears. If I had a little stonger back, I could have walked out with a pair of 9's and a 7 without detection. Even then Phillip wouldn't have known somethings were missing ... There are that many cream-of-the-crop Marantz tresures in throughout the house... Some people would die to get hold of a pair of 9s but three pairs of 9s under single roof? Life just isn't fair...

Thanks for sharing your audio Mecca, Phillip.

WOW! Nice vintage system, Phillip! I suppose you prefer the pair of Marantz Consolettes to the Model 7? What brand of output tubes are you using in your Marantz Model 9's these days?

Very Cool!

Thanks! Just having fun with it/phillip

Some terrific old gear!!

Enjoy!!

I have Marantz 7 and 8b that need restoration. Do you have a recommendation as to who can do this?

I presume you restored them to their original status and didn't try to "improve" them.

Thanks

My God! You are my HERO! Triple Stacked KLH 9s RULE. Keep up the great work. We need more vintage(i.e. Musical) here on Audiogon. It just does not get better than KLH 9, Ampex 300 series.
Thanks for posting.
