Now that's a funny typo!Are there not two different weed linear tracking arms?
Now that's a funny typo!
But yes, Reed makes 2 versions (5T and 5A) that utilize the same principle.
Sorry Marty. I often simply dictate into my phone. Ron was considering a Reed linear tracking arm and he described one as more complicated than the other as I recall. Perhaps the difference was the laser I can’t remember or the motor.
That's the one made in The Netherlands ;-) and sold in Colorado......Now that's a funny typo!

Congrats! What a great speaker by all accounts...big fan of your CJ GAT 2 (was a 20+ year consecutive owner of CJ preamps from CJPV14L to ACT 2, CJ GAT 1, CJ GAT 2...so grainless, extended and natural. Imagine you spent a lot of time debating whether to go another SS amp, CJ reference amp (apparently the latest ones are phenomenal)...what led you to CH?
Dear LL21, thanks a lot!! It's almost 2 months since the delivery of the Wilson Audio Alexx V speaker and the initial excitement has started to calm down now. It's really an overwhelming experience for me since I could never imagine owing such a "huge" speaker in my life. Anyway, I am a big fan of the conrad johnson gears, having owned some of their pre & power amps for the past 20 years (premier 16, 17, Act2, Gat2, 350, 12 mono etc). cj gears are sort of more affordable to me and overall providing very good performance and musicality, and I always prefer a wireless remoteCongrats!

Wow...you are a much bigger CJ audiophile than I am...and I have been a proud owner of CJ preamps for over 20 years consecutively. Unfortunately, on the amplification-side, I never got past the MV60 60-watt amp (which was a very special EL34 amp)...nearly got the Premier 350 and thought about upgrading an old pair of Premier 8s, but did not. Impressive on your part! And yes, entirely agree with you on CJ...they really and truly have lived up to a hard-working, down-to-earth design ethic of purity, no grain and natural music...expensive but genuine long-term value.Dear LL21, thanks a lot!!

WOW LL21, you have the Robert Koda K15EX Super Ground !!!!! I have auditioned in two separate occasions during my home visits previously and it must be one of the best preamps ever produced despite the huge cost. I just couldn't believe my ears when auditioned to this gear. So once again congratulations LL21, what a lucky guy you are !!!!!

if by the 4th time constant he means the so-called "Neumann pole", please read thisZanden Phono Stage “time constant” implementation- have we really heard our vinyl before?
We are all keenly aware that the past two years have seen what many consider significant advancements in the area of digital music reproduction with the release of several landmark products such as the Taiko Extreme server and software, the Lampizator Horizon DAC, the Wadax server and DAC, and other significant offerings from MSB, Total DAC and several others. User impressions are pretty much unanimous. Digital continues to improve and delivers SQ well beyond what we could only imagine a few short years ago. The phrase uttered around the world is “the gap is closing”, which has been a mantra of audiophiles for generations when comparing the SQ we get at home compared to live music. Even if you use the analogy that we continue to get closer to a doorway we can never get through, we enjoy our incremental improvements and often consider them revelations. For quite a few years, these improvements seem to be more prevalent and noteworthy in the digital space. While the advancements on the vinyl side includes better turntables, arms and cartridges, the basics of the electronic circuitry that processes the amplification of miniscule voltage signals that amplify moving coil or moving magnet cartridges so that they are suitable for further processing downstream have not really changed much over the past 40 years or so since the RIAA was “standardized” as the basis of the EQ correction necessary for these phono devices to function well. Until now.
Kazutoshi Yamada, the CEO and Chief Brain Officer who runs Zanden Audio Systems in Osaka, Japan released his 1200 Phono stage 17 years ago. Universally applauded, Yamada-san has now implemented a major design upgrade which he believes achieves the designer’s ultimate goal of perfect reproduction in vinyl replay. His latest is the Model 1200 Signature which is the culmination of continued improvements made in the Model 1200 series over its long history. It is a fully balanced LCR type phono pre-amplifier with Zanden’s unique 15 types of equalization curve switching, heretofore unseen in the audio world. A part of his latest advancements such as various EQ curves, were already seen in the earlier 1200 Mk3 (single ended only) which I own. But recently, I sent my phono stage back to Japan for an upgrade that incorporates many of the main advancements of the 1200 Signature (which differs from my unit by offering balanced as well as single-ended outputs). The modification to my 1200 Mk3 is now called the 1200 Mk4. According to Yamada-san, “the hearing experience is comparable to listening to a master tape and makes one forget that the source is a vinyl disc”. So what is the magic that Yamada-san incorporated to take vinyl reproduction to the next level?
The essence of his new technology is the incorporation of circuitry that corrects for the “4th time constant”. While this term suggests some sort of wacko phenomenon involving the space time continuum, in reality it is newly implemented circuity that Zanden now incorporates to allow for the full recovery of information that is embedded in the LP cutting machine which has never been previously available for the several EQ curves typically employed by the major LP manufacturers. Zanden believes that high-end audiophiles must have this functionality if their ultimate goal is to achieve high fidelity in sound reproduction in order to listen to the exact original recording of the LP when it was cut.
What exactly does the the 4th t/c circuity do? To begin, it effects both the amplitude of the frequency response used in the every EQ curve that the Zanden phono stage employs (RIAA plus 4 more) as shown here

Shown another way, here are the difference of the EQ curves with high t/c correction versus the RIAA curve with and without t/c correction.

Thanks for the feedback Michael. Of course, it would have been better to suggest that in your experience it is marketing hype. That certainly was not the case for me. Do I agree with every setting recommendation? Of course not. But that doesn't preclude trying others to see if there is a benefit or not on any given LP. In my case, the benefits were significant across a very wide range of LPs.if by the 4th time constant he means the so-called "Neumann pole", please read this

Cut and Thrust: RIAA LP Equalization Page 2
In the summer 1978 issue of Stereo, technical editor Edward J. Foster wrote of the IEC revision: "What point is there in paying literally thousands of dollars for a stereo system capable of response to below 40Hz and then blowing it all on a sloppy subsonic filter?...The record-warp problem will...www.stereophile.com

I appreciate his designs but some of his beliefs are completely misguided. He suggests different curves for Blue Note and Prestige records when both were cut by Rudy Van Gelder on the same lathe with the same electronics. He suggests a specific curve for Vanguard records when Vanguard records, being a small label, had its records cut by RCA, and in some cases Columbia Records. I could go on. But the idea that finally you will hear what's on the record that you've never before heard, and that finally it will sound like tape is nothing but marketing hype.
The recommendations are using curves as tone controls, the opposite of what’s being claimed, especially regarding the 4th pole. It’s not an opinion! An opinion is that you prefer a different curve than the one that correctly decodes the record. Some things are cut and dried facts and some things are opinions to which everyone is entitled!Thanks for the feedback Michael. Of course, it would have been better to suggest that in your experience it is marketing hype. That certainly was not the case for me. Do I agree with every setting recommendation? Of course not.
