    Fantastic balanced sound, extreme durability


    Been using At440ML and AT440MLa for 15+ years, Rega P3/RB300 arm. Less fussy setup than other carts I tried. They both survived massive abuse. They are virtually indestructible! I clean the stylus after each record, and there is no wear on either styli at all. They will both outlast me. Old, beat-up scratched-to-oblivion records can sound fresh and alive, full of detail, barely any surface noise when thoroughly cleaned. Cleaning your records (VPI, etc) is a MUST! The ML/MLa will pick up the slightest amount of dirt, even when surface looks pristine. Cleaning stylus after each record is a must. Tracks GREAT. On better arms (yard long wooden arm) it tracks EVERYTHING - even warps that touch the cart body(!) Upgrading your arm/system the cartridge will keep up. Yard long arm completely transformed everything - such detail, base level, air, imaging that surpassed my wildest dreams. Powel Biggs / organ recording you can hear the soft breeze in the cathedral when he's not playing - never heard that on any other setup. Hot A/B switching sources blind test CD/LP with Weather Report - Heavy Weather (using Micromega Stage 3 CDP / RB300 arm): LP was more dynamic, better base, more air, more body, better tone, same level of noise floor. To improve, if you can: cryogenically treat the body (without the stylus!) You'll get way more detail. If you treat stylus as well, sound will be rigid and sterile. Insanely great value for the price. Listening mostly classical and rock.

    Great "Budget" Audiophile Cartridge


    I've had this cartridge over a year and typically use it as a backup on more worn lps. For newer discs, I usually use my AT150MLX. The AT440MLa is what I really consider the beginning of what some might call "audiophile" cartridges. The stylus is of a very advanced shape that Audio Technica calls "MicroLine". It tracks the record grooves better than any other shape I have ever used and slightly warped (and very warped!) records don't usually phase it. The sound is clear and what you might call analytical or detailed. You can pick out individual instruments or voices that would just all seem to run together for me using other cartridges. As cliche as it may seem, I really did hear certain aspects of music on my records that weren't obvious before I used this cartridge. The break in period is about 40 to 50 hours. At first the cartridge tends to be a little "bright" focusing on the highs a tad excessively, but after break in it mellows off and isn't neutral, but is a lot more even. I enjoy the sound a lot. The only other cartridge I have used that sounds smoother and more relaxed is the AT150MLX. I also think the specs might be a little better in real use because a friend has also successfully used his 440MLa for quadraphonic records that require a very high frequency response over what this cart is rated to. If you are looking for a good cartridge and don't want to spend too much, this is a great option. It has a great sound and is very easy to live with if you only wanted one cartridge. It is a great upgrade for the AT-LP120 turntable and other vintage Japanese direct drive turntables that use a similar medium mass tonearm.

    No more inner groove distortion!


    I bought this cart to replace a well known competitor's cart that I found my self re-setting up about once a week. No matter how I tweaked it, the last two tracks on each side of the record were terrible sounding: sibilant, distorted, etc. I even updated my turntable � the cart's manufacturer assured me I must be doing something wrong! Well, I finally did some research and decided to get this cart. It's only got about 3 hours on it, but already I can say this: my inner groove distortion is gone. GONE. I didn't believe this was possible! But what's almost cooler is that I had a stack of records I was ready to trash because they sounded totally worn out on my old cart. Distorted, treble all gone, etc. I threw an especially "trashed" LP on my turntable to see what the AT440mla would do with it. To my COMPLETE surprise, the rumors about this cart are true: it dug down deep in the groove and found undamaged vinyl. EVERY record I was ready to throw out sounded good enough to hang on to with this cart. Some sounded good, others sounded FANTASTIC. Additionally, especially with newer, cleaner records, this cart has extremely low surface noise! Some call this cart bright. And while it does show a rise in the treble, its reproduction of music is faithful. For example, an LP whose CD counterpart is also mastered on the warmer side sounded spot-on; same as the CD, no extra treble. Records that had previously sounded like they were lacking high frequency detail came alive with this cart. I have yet to feel like I need to roll off the highs as I listen to the AT440mla. Its sound is not fatiguing to me in the least. And it's not even broken in! So, to summarize: If this cart hadn't worked, I was ready to give up on vinyl. All this talk of LPs being able to rival CDs in sound quality was sounding a bit ridiculous to me UNTIL I tried the AT440mla. I never knew vinyl could sound so clear, full, natural, and dynamic. If you have a decent turntable and an amp/speakers that can do justice to the increased detail this cartridge reveals, the investment will be well worth it! Just be careful with it! I've never seen such a tiny cantilever in my life, and I can't even make out the diamond. You'd only have to drop this cart on a record once to do some damage. Respect it, and it'll respect your records!

    Very good sound & avoidance of record wear


    This cart is high-quality for a number of reasons. 1. the tracking force is kept to a low number(1.4gr nominal) 2. Ohno Continuous Casting Copper used in the internal wiring=better detail retrieval and imaging. 3. dual magnet for separation 4. Perhaps most importantly, the MicroLine stylus is very easy on the grooves and keeps wear of your records to a minimum.

    The best value for your dollar


    I have owned many cart's over the last forty years, this one is the best value of them all. The overall balance of the response is it's biggest asset. The soundstage is wide and open. This is mounted on a mid priced 20 year old Technics TT that has never sounded better. I have only heard two cartridges that sound better than this one. One is the AT-oc9/lll which I have on another TT, the other is on the Mcintosh turntable which at $12,000 (yes I said TWELVE THOUSAND) is still on my wish list.

    Truly excellent cartridge


    I've had this cartridge for at least 5 years. It's very musical sounding, captures fine details and delivers expert tracking. It also works quite well with the less expensive and easier to find AT120E replacement stylus.

  • Q & A

    Are any other AT replacement stylii compatible with this cartridge?

    Thanks for you inquiry. The VMN40ML stylus will work with the AT440MLa cartridge. You can also go to one of our dealers LP Gear, they do have the ATN440mla stylus avalible on their website.

    I'm in the process of installing a phono amplifier and I need to set the input gain,input impedance, and input capacitance for my cartridge (AT440MLa). I can't find this information in my audio-technics literature. Also, is this a low or high output cartridge? Thank you for your help.


    Thank you for your inquiry. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Will this fit the Denon DP-300F?


    The specs for the Denon DP-300F Turntable state that the acceptable cartridge weight range is 5 to 10 grams. The removable headshell accepts standard half-inch mount type cartridges. The AT440MLa Cartridge is a half-inch mount type, and it weighs 6.5 grams so yes it will fit.


    Anti-Skate setting What is the best way to set the anti-skate for the at440mla cartridge? It's mounted on an AT-lp1240 turntable. The counterweight is set to 1.4 grams.

    Installtion instructions Hi, What is the best way to put a cartridge on a turntable? I have an AT LP120 turntable and an AT440MLA cartridge. Currently the only method (I know) to use for me is an Audio Technica overhang gauge. I centre the tip of the stylus on the triangle and I ensure the needle is level with the end of the gauge. I hear I should use a protractor? If you have any advice please let me know. As I am technically that gifted, I am looking for simple way to do this. Could you please be as specific as possible. . Any help would be greatly appreciated! Regards Ruud Palmer


    An alignment protractor may yield better results. I recommend the Technics Baerwald Arc Protractor which is available for download from Make certain that the protractor prints to scale. In addition to setting setting stylus overhang, a cartridge alignment protractor will also set the correct effective tonearm length and offset angle.


    mounting a AT44MLa cartridge to headshell for the AP-LP240 turntable The mounting slots on headshell are about a half inch long. When mounting cartridge what is to proper position in the half inch of slot to screw the cartridge down?


    Thank you for your inquiry. You will need a protractor or overhang gauge to set this properly. These can be purchased or you can print out the Stevenson alignment protractor (free download from
