A new player in the quality Mono cartridge game

For awhile there, if you wanted a mono cart to get the most out your new mono Beatles collection, other mono reissues, or vintage mono LPs, there were the budget offerings from Grado, a big price gap, and then the more expensive good stuff. The elliptical mono Grado goes for around $150.

But now the Audio Technica AT MONO3/LP, a HOMC, is available in the US. The link goes to the official importer, LpGear, who prices this $299.99 cart at $189.99. However, I also found that this cart is available from Amazon for $112.65. Worried that the unofficial import puts your purchase at risk? For a mere $12 extra you can buy a 2-year protection warranty.

I ordered mine via Amazon Prime on Sat. Oct. 24 and it arrived today.

This thing is NICE! 1.2mV output, which is plenty, conical stylus (don't know if it's nude or not, but it *sounds* nude), tracking force range 1.5-2.5g. I'm breaking mine in at around 2g.

Even fresh out of the box, this cart's a revelation. I started with "Within You Without You" from the new Beatles Mono vinyl reissue. It's really something when you play a mono record with a cartridge that produces no signal in the vertical plane. The noise floor drops down to the indiscernible. In fact, even cueing the needle makes very little sound thru the speakers.

Everything on Sgt. Pepper's sounded richer, lusher, more distinct, more dynamic, with great treble extension and no hint of sibilance. I followed it with Analogue Productions' 3-LP 45 rpm remaster of Nat King Cole's "After Midnight." Fan-TASTIC! I thought Nat was in the room before, but the dynamics, transparency, and truth-in-timbre reached a height I hadn't heard on my rig up to now.

I finished my mini-audition with a *real* mono record, an original mono Columbia Masterworks pressing of "Grand Canyon Suite" performed by Eugene Ormandy and The Phily Phil. Again, smoother, quieter, more dynamics. It showed its age a little bit, but I think I could bring this 55-yr-old record close to the reissues with a steam cleaning. Even without it it was very satisfying.

Folks, if you have nothing but the new Beatles mono reissues and have an easy way to switch cartridges or set up a mono rig, this cart is so worth it.

Right now I have around 13 Beatles mono LPs, two Beach Boys reissues, the Nat King Cole, some old Columbia Masterworks and shaded dog Orthophonics, mono reissues of Prestige and Miles Davis LPs, and some mono pressings of '60s pop.

I'm thinking of separating all my mono vinyl into its own shelf so--when I mount the AT Mono3 LP--I don't have to sort through my entire collection to play the compatible LPs.

BTW, if you decide to go after this cartridge, make sure you get the AT MONO3/LP cartridge, which is for mono LPS, and *NOT* the AT MONO3/SP cartridge, which is for 78s.

Lew,

I plainly said the reviewer is a dumb ass, whoever that might have been. I'm going by what you said, not having read the review myself. The Zero will damage a stereo groove or they wouldn't have put that caveat on their site.  The cart does have some vertical compliance, 10cu, but is only designed for lateral movement. 

I believe the AT mono carts have .65 mil tips. Close enough.  Of course you can play a mono or stereo LP with a spherical. People do it all the time with a DL102 or 103 and numerous inexpensive carts.  I assume you would want detail with mono records as with your stereo ones. Do you listen to your stereo records with a spherical tip? 

The smaller minor radius of a more advanced tip profile will give you more information in mono, just as it does in stereo. I can hear loss of detail, especially in harmonic content, in comparison to my stereo carts with advanced tips. The mono cart has a better presentation with mono records and spatial clues are improved. Sometimes things are revealed in the mix which are not noticed before, but for detail, it's like listening to a stereo record with a spherical tipped cart. 

Regards,

Sorry. I get it; you meant to say that the person who claimed that the Zero would not damage a stereo groove was incorrect, and you cite the blurb from the Miyajima website as evidence.  Seems like you're correct. Fremer misspoke, if it was Fremer.

Now, as to your critique of spherical styli, I have no basis to argue the point.  It's been many decades since I ran a spherical stylus across an LP.  However, to be as scientific about this subject as possible, which is "not very", you would have to say that your personal experience of a spherical stylus in comparison to some other shape, is your subjective opinion. In other words, it's anecdotal, not necessarily statistically valid.  I speak here only of spherical stylus on mono LP.  I would readily concede that a spherical stylus can be beaten, on a stereo LP, by other shapes.   What mono cartridge with spherical tip have you auditioned? Thanks for your patience.

If we're talking microgroove - reissues, mid '50s or later (my assumption), then a mono record is no different in that respect than a stereo LP.  You're making this more mysterious than it is.  I've given you this Ortofon link before:

http://ortofon.com/hifi/products/mono-series

Spherical styli were the most commonly used geometry up to the beginning of the 1960s. Consequently, most records from the first 15 years of microgroove records have been played with a spherical stylus. This will not, however, mean that mono has to be played with a spherical stylus. In fact, elliptical types as well as line contact types can be highly beneficial for mono records from the mid 1950s and upwards (see figures below). The line contact types, specifically, will ensure an improved high frequency response due to the slim shape. Also the distortion from the pinching effect, which occurs when the stylus is pushed upwards due narrow high frequency grooves, will be reduced substantially.

Replaying an old mono record, which probably has been played only with a 25µm spherical stylus can be replayed in a different unworn location of the groove by using an 18µm spherical stylus or, even better, an elliptical or line contact stylus. Choosing one of these diamond profiles will dramatically increase the stylus’ ability to reproduce the inscription with detail and accuracy.

Johnnyb53:  Thanks for the tip on the AT Mono3/LP.  I got mine from Japan last week and am very happy with it.  Really sounds like a more expensive cartridge and I only have about 10 hours on it so far.

I did compare it with using a stereo cartridge and the mono button on my integrated amp.  For me there is no question  that the mono cart sounds better even though the cartridge I compared it with (Grado Gold) costs twice as much.  Especially on old 45s with a mono preamp (TDL 4010).

Now I am wondering how much better the AT MONO33 is?

I just don't see the need for a mono cartridge...I play mono records fine with no annoying noise.  The sound comes out from between the 2 speakers and I can enjoy the music fine.
