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.

Fleib, Your experience with the Mono switch is wildly different from mine. I hear a pronounced improvement with the mono switch engaged, using a stereo cartridge on a mono LP. It's so obvious that if I have forgotten to flip the switch, I am reminded by the inferior sound to do so immediately. Further, the improvements are just as one might expect, a reduction in noise, an enhanced clarity of the treble, and a stabilizing of the image. This is when playing jazz LPs that are no older than mid- to late 1950s and so would be true "LP"s. Many are modern re-issues of same. I don't own any 78s or late 40s records of any type. What is the vintage of the mono LPs that you own which do not respond to the mono switch cure?
Johnny, What is a "phono head with a mono switch"? I think what you're talking about is combining channels AFTER the cartridge but before phono amplification. That can be done if all else fails, but it's not the optimal way to go, because in such a case one channel of the stereo output of the cartridge "sees" both the other channel AND the phono stage input impedance in parallel. This affects the loading of the cartridge in an unpredictable way but usually not a good way. A typical mono switch on a full-function preamplifier would be placed in the signal path between the phono stage and the linestage, just before the volume control. I own two such preamplifiers, both vintage: a Klyne 6LX and a Quicksilver. The latter can be purchased typically for around $1000.
Fleib, I responded to your 11/07 post without having read your 11/09 post. Indeed, it may be that you have not given the "mono switch" solution a fair trial. And it may be that your experience with a Y-adapter was affected by the impedance phenomenon I described.

Fleib and Johnny, Don't worry; I am eventually going to buy a mono cartridge just out of curiosity.
Lew,
I'll try the mono switch again. It did help, but not like a mono cart.
Something to consider - there is always a difference between channels with a stereo cart. Any small azimuth difference will contribute, as will skating. There is no perfect anti-skating setting. Skating varies with groove velocity and offset angle. Except for 2 null points on the record, there is always a phase difference between channels w/pivoting arm.

These differences are combined with a mono switch and eliminated with a mono cart. I'll dig out that Mozart record, clean some thrift store finds and test the mono switch again.
Regards,

I just meant a mono switch at the phono stage instead of the line stage. Beyond that I don't know and don't care. To me the mono switch is a footnote in the history of high fidelity. Handy if you need one, just another switch if you don't. If you gotta have a mono switch, you're looking at shopping for 40-50 yr-old preamps, getting a custom unit or going DIY.

Since I have a TT with interchangeable headshells (as do you), I'm happy to
swap carts in about a minute. The ATMONO33/LP (you know, the topic of this thread?) starts off with PCOCC copper wiring, extracts a pure mono signal at the source, suppresses the vertical plane a minimum 30dB, and just sounds quiet, smooth, luscious, and right.

This cartridge makes my latter day mono reissues sound cleaner and more dynamic. My '50s and '60s thrift shop mono albums have gone from unlistenably noisy to very enjoyable.

For anyone with some mono albums who has an interchangeble headshell, second tonearm, or rack space for a mono turntable, I highly recommend going the mono cartridge route. For $112.65 you can get a $300 list (built and sounds like it) HO moving coil true mono cart that'll light up anyone's mono collection

I'm done talking about mono switches.
