Audio Technica AT150MLX finally gets some respect

I've been at this audiophile stuff for over 40 years. At this point I'm pretty confident of being able to ignore preconceived notions and evaluate the strengths and weaknesses of a component in my system. Still, once in awhile it's nice to get some validation--a sanity check.

I've been using an Audio Technica AT150MLX MM cartridge for over 3 years. Since getting it I have improved the downstream components and cabling a few times, and each improvement, rather than revealing limitations of the cartridge, has shown it to have a great tonal balance, high resolution at its price point, excellent trackability, low level detail retrieval and excellent dynamics.

Still, when I opened my January 2012 issue of The Abso!ute Sound, I was pleasantly shocked to see that the $449 list AT150MLX had been named Cartridge of the Year! Given that the $5000 Benz LP-MSR and $13,000 Clearaudio Goldfinger were also mentioned on that page, it wasn't that the AT150MLX won in absolute terms, but for performance value.

It's as I suspected from my first listen. If you want to know where the threshold into a high end cartridge is, it's the AT150MLX. I got mine in 2008 when the dollar was strong and these things were going for $250. But even at the currently available $325 they are pretty unbeatable.

Back in the Spring of 2008 I asked the A-goners about what cartridge to move up to from the DL-160. I was considering the AT OC-9 or the Denon 301 II, but a number of A-goners made a compelling case for the AT150MLX. I took them at their word and have never regretted it.

If you want the best out of this cart, you *must* give it a capacitive load between 100 and 200 pF. In fact, my highly adjustable Jolida JD-9A phono stage indicates that the real sweet spot is right around 150 pF.

Anyway, thanks A-goners, and it's also nice to know that when the stylus wears down, I can just send for a replacement plug-in stylus $225.

Johnny,

It's nice to hear an audiophile who is actually happy with what he's got! More power to you.

Almarg, I appreciate your explanation. It helps.

I am running a KABUSA Pro S40 which is an Ortofon cartridge that fits into the arm without a headshell. I like it alot especially since I played with the capacitive load switch on the Jolida.

Getting that right added detail and helped to separate the instruments on good recordings.

However, I am getting the itch especially after reading this thread, which is very complimentary to the AT150MLX.

Trouble is it is a $450 cartridge to replace the $360 Ortofon (which replaced a Denon 103R).

Not sure what exactly what I would hear above and beyond the Ortofon with the AT150. Anyone have an opinion on that?

For what it is worth, I think that the KAB modified Ortofon is more alive and organic in my system compared to the Denon which seemed more detailed but not necessarily in a good way.

If you know where to shop, you can get an AT150MLX for just under $325. To get its best, however, it's wise to get LPGear's ZuPreme Headshell, which adds another $55 to the equation but brings azimuth adjustability to the table.

I also use a Technics SL1210M5G with the KAB fluid damper. I've also added a few other things to control resonance and vibration. Just because I wax all poetic about the AT150MLX doesn't mean it's a better choice than what you have. The KAB Ortofon has the advantage of factory-perfect alignment and balance. It eliminates a set of connections as it plugs directly into the tonearm. There should be fewer cart-headshell resonance problems as there is no headshell.

I bought my AT150MLX in 2008 when the dollar was strong internationally. I got nice fur felt fedora hats from Australia for 67 cents on the dollar and I got my AT150MLX for $259 from LPGear. J&R had them for $250 and free shipping. For me it was the low cost alternative to the KAB/Ortofon setup that you have.

Hi Jonnyb53,

I have the AT150MLX on my turntable (Technics 1210M5G) as well. And I agree 100 percent with your review. It's definitely a great cartridge, and you would have to spend a lot more to get arguably better sound.

why does the original poster state and I quote -

"If you want the best out of this cart, you *must* give it a capacitive load between 100 and 200 pF. In fact, my highly adjustable Jolida JD-9A phono stage indicates that the real sweet spot is right around 150 pF."

I don't have to do anything esoteric with my 150MLX on technics 1200mkII aside from proper alignment with Protractor and balance and weight.
Nothing else needs to be done in my case.
Why does this person suggest this?
I get the sense that you think I'm overcomplicating installation of an AT150MLX because your experience was a simple plug-n-play. In many setups that will be the case. But it just happens that your turntable rig is a near ideal match. Your turntable has a built-in interconnect that has a total capacitance of 100 pF. Your phono stage most likely does not add any capacitance. So your AT150MLX "sees" a capacitive load of 100 pF, which is near ideal.

That's not always the case, however. Many turntables have RCA jacks instead of hardwired, and the interconnects the user selects may have a capacitance ranging from 50 to 300 pF. And some phono stages have a minimum input capacitance of 200 pF. The very popular Musical Surroundings Phonomena II is one such. Therefore with some rigs you could wind up with a capacitance of 400+ pF and not realize it. Dropping an AT150MLX into that signal chain would not be as satisfactory as your and my experiences. So I'm qualifying my enthusiastic recommendation for those who have setups that aren't as naturally compatible to the AT150MLX as our turntables and phono stages.
