Grado Epoch 3


I have been shopping new cartridges for my Artisan Fidelity (henceforth AF)  NGS SE. My table started life as an AF NGS. I had Chris convert it to the four arm capable ~350lb variant now sitting on my stand. I currently have the table outfitted with two Kuzma 4 Points, an 11" and a 14". I am still awaiting the update of my third arm which is a Technics EPA 100 MK 2. The technics will hold the London Reference and is having the bearing replaced with lab grade saphires. The 14" 4 Point is awaiting delivery of the Ortofon MC Diamond which replaces my former MC Anna. I was really interested in the Epoch 3 based on my own intuition and the description of the motor. I was not terribly moTved by the reviews I've read. 

I spoke to Todd of Todd the Vinyl Junkie fame concerning the Grado line of transducers. Todd is very knowledgable and a real audio enthusiast. I have bought several far less costly items from Todd in times past so I was familiar with his company. Todd graciously offered to allow an audition of the Epoch 3 which he had on hand, but John Grado found out about this and arranged for me to get a new unit for audition. Talk about service!

This is my only experience with Grado Labs. The cartridge arrived in a short period of time, and I set it up on the 11" arm using Analog Majik 2, my SmarTractor and MY EARS. Initially it sounded very nice. It has a weight to it much like my former reel to reel. It was exciting and very impressive the first 26 hours but then it started sounding kind of boring to my ears. I changed the VTF from 1.8g to 1.65g and this was part of the problem. I should have been running it in at the upper limit of the specified tracking force range. I set it to 1.854g and let her go. 

The cartridge started to open-up and now showed more vigor and life, it was energetic but not as airy, or bright as some MC's I have heard. Once I hit 57 hours she was singing again and only got better up to about 67 hours. The highs were all there as I used my AMR CD 77.1 as a reference on certain pieces of music including vinyl, I had digitized to 24/96. The highs were there, just not the way my former MC Anna did highs. The Grado has a weightier center of gravity if you take my meaning. As the cartridge continued to run in between 67 and ~97 hours it waxed and waned from good too great to, "I don't like what I hear and I am walking out of my man cave and going to bed". I am now at 104 hours, and it sounds glorious. 

I used my DartZeel NHB-18NS and AMR PH 77 phonostages with the cartridge and it sounds fantastic with both units. I have settled on leaving it connected to the PH 77, the combination is really special. The Zeel sounds a little more romantic, which is counterintuitive as the AMR is tubes and Zeel is all SS.

I used the London Reference with the SW1X LPU III Balanced phonostage for comparative purposes. The LPU III Balanced is a wonderful full sounding end of road stage with 48dB of gain. Joe over the Lotus Group was kind enough to hook me up with the LPU III. It's a real shame this piece is not talked about more, it would put some pieces that magazine reviewers pump-up to a flat out shame.  It was perfect for the London. The LPU III does not have enough gain for the Epoch 3 therefore while I did listen to both cartridges on the 4 Point (love the 4 Point and its removable headshells) I optimized each cartridge with the stage that best fit its specifications. Both cartridges are super-fast and I mean fast!!! The Grado has a wider soundstage and is simply more luxurious. Don't you hate car analogies? Well TOO BAD, here's another one LOL. The Grado would be an AMG S65 while the London is Porsche GT3. Both fast and agile but they do it differently.

On piano the Grado is big and real sounding, the London is not quite as big but on some pieces the London has a transient speed with respect to hard percussive hammer strikes that no other cartridge I have heard can match. I have decided to keep my London.

The Epoch 3 It is one of my favorite pieces of gear and it makes music like very few other cartridges I have heard. The highs are all there, they just don't slap you in the face. It sounds ridiculously good on classic rock and jazz and even classical. I have read that it probably won’t be fully run in until about 150 hours so I still must see what more there may be to come. 

I did hear some hard sibilance with the Grado and that concerned me quite a bit. The little pamphlet that comes the Epoch 3 states that the front of the cartridge should be 90 degrees with respect to the surface of the vinyl or 2 degrees down at the back (lower the tonearm). Analog Majik 2 also showed the best IM distortion number when it was lowered. Problem is, I found it lifeless and boring! I ended up with the front of cartridge 2 degrees forward (tonearm a bit higher). The sound was spectacular but then I started noticing some sibilance. Did I have to endure sibilance in order to get the life I wanted out of the cartridge. This was the dilemma.

I spoke to John who is just about one of the most unpretentious and nicest guys in audio you will ever run across, and he mentioned the cartridge should be 2 degrees forward before I ever told him that is where I had my unit. John is revisiting the pamphlet which may be old material from another model or a misprint. So then, what about the sibilance. I recalled that one of the biggest offending albums was my copy of Jennifer Warnes The Hunter. I played it again and there it was, slapping me right in the face, HARD! I then recalled that some years ago I'd digitized that piece with my 4 Point 11" running the Ortofon MC Anna on my NGS using the ADC built into the AMR PH77. These files are on my HDD and part of my Roon Library. I did this to quickly reference what a tonearm/cartridge/stage combination sounded like for comparative purposes. It was fortuitous that I had done so. I played the same MC Anna digitized piece back and bam, slapped in the face again by sibilance. Problematic vinyl was the culprit. 

One evening while I was listening, the system was sounding so real and fantastic, I found myself happy and upset at the same time. Happy because of how convincing this cartridge makes music sound real, upset because right then and there I knew I would be out $12K. 

The Grado Epoch 3 is one of the finest cartridges I have ever heard and I am glad it is resident in my system.

So a correction or two. I went down to the cave to check the settings for the PH 77 and I have been running the Epoch 3 in MC mode (not MM/MC Hi as I mistakenly mentioned above) at 60dB of gain loaded at 47k ohm. I keep the display of the PH 77 off unless I am changing its settings. I tried higher loading and the result was exactly what I expected it would be, a dull warmed over, and seemingly slower sound delivery. I tried 350 ohms, that was like putting a blanket over the system, and then 500, 750 and 1500 ohms. It got progressively better as the cartridge was more lightly loaded, but once back to 47k ohm, magic again. In my system with the AMR PH 77 the Epoch is best at 60dB, 47K ohms. I am not implying that it wont or can't sound better in another system more heavily loaded. YMMV

noromance:

You are correct concering  proper run-in with audio gear. My unlce used to go through so much gear and then he would tell me how for instance one dac smoked the other. I stopped really putting any stock in his assertations because he might only have a piece of gear for 2 or maybe 3 weeks before it was out the door. I would always tell him that he actually has no idea how the piece sounds because he never gave it a chance. 

I can't think of any reason to do jeweled bearings on an EPA arm aside from nostalgia.  It's also exceedingly difficult to get anything approaching grade 5 or better.  Last I looked grade 25 is all that was reasonably available.  

jpjones:

I believe another reason I went with the jewels was due to some concerns around noise with the nitride or ceramic bearings (I think it was a concern with the ceramics) but as I stated it has been a minute and I don’t recall all of my conversations. I am, however, paying attention to your statements and may very well try the Nitride bearings. My saphires were expensive and come from a Swiss Lab. I don’t have the specs in front of me but the sphericity was, well Swiss lab grade :) very high.

FYI my SP 10MK 3 based NGS SE does use your Fidelis Analog FA6042 Pitch Synthesizer. Thank you for that contribution!

Really interesting article. I have not heard the Epoch 3 but recently installed it's little brother  - Aeon 3.

I like you eventually settled on raising the rear of the cartridge slight above horizontal and it made the cartridge come alive. Also use it on MC settings on the phono stage at 10000. A much more involving sound. Thing which has blown me away with cartridge is the detail it retrieves from the groove but without surface noice - no idea how they have managed this??
