Ana Mighty Sound 103.3


I am offering a quick description of my modified Denon 103r. I have read reviews about how great the already good sounding Denon 103R or plain 103 can be once re-bodied. I am the type who has to try it for myself in order to be sure eveything is optimized. After looking at the various companies performing mods, Zu, Sound Smith, etc. I decided to go with Ana Mighty Sound in France. One of the things that helped me make my decision was the fact that I mistakenly thought the cue was up on my SL-1200 GAE and I ended up knocking the cartridge into the platter thereby scewing the cantilever. Choice made, get the mod :)

While I waited I bought a second Lp Zupreme Headshell and a second 103r so that I could do a head to head comparison once my modified 103r was returned to me.

I received the modified 103r (henceforth referred to as 103a, for "103 Ana") this past Friday so it is REALLY new, read not run-in.

Even so, cold out of box it is better than the stock unit but after about two hours it is surprising me with just how well it is performing. It is at this point far beyond the 103r. Whereas my mac mini with LPS and Uptone JS-1 power supply (also with the fan kit), iUSB 3.0, x2 iFi Gemini II USB cables, AMR DP 777 se, HQPlayer and Roon, easily outperforms the 103r, the 103a has pulled slightly ahead of my digital on the admitted limited testing I have been able to do.

I purchased the 103.3 with the Malachite body, boron cantilever with micro-ridge stylus and the 22 degree angle adjust for the modern stylus (Ana Mighty Sound are the only modifiers I know of who correctly adjust the angle of the cantilever on the 103 after installing a more modern and acute stylus).

I now have a cartridge that is absolutely world class for 783 Euro (plus the original) cost of the 103r. I have compared it directly to my London Reference ($5K) which is mounted on a Schick Oil-Soaked graphite headshell. They sound very close but the 103a has a bit better body on female vocals. If 50 is dead neutral I would say the London is 49. It is on jazz or blues, basically anything with drums, piano or large dynamic swings and peaks where the London just simply cleans the clock of any other cartridge I have heard. The London very much reminds in some regards to my R2R running 15ips.

I am going to order another Lp Zupreme today so that I can compare my Ortofon MC Anna to the 103a.

I will say that my SL1200 GAE with the SPL Phonos and my 103a is absolutely world class. I don’t know at this point if I will ever purchase another expensive cartridge. I actually was not prepared for my secondary analog rig to take that big a leap in performance. I am very very pleased with the purchase.

I will continue to comment as the unit runs-in.

The linear power supply project for my SL 1200 GAE was delayed do to extreme flooding in the area which delayed parts delivery. That project will probably commence in about the next 4 weeks and I will write that up. I am glad it happened that way as I don’t like changing more than one variable at a time.

Until next time.

Thanks for the update @audiofun  
Would you say that 103.3 is a great option if one wants to buy a serious $2k cartridge ?

Which phonostage do you use primarily ?
Thanks @audiofun , how does the SPL Phonos compare against other higher end phono stages like the Pass or your AMR ?
Thats very interesting @audiofun . I use a Ortofon Cadenza Blue which has an output of 0.5mv. Will that pose any noise issues with SPL Phonos ?
@audiofun , do you have any idea about the Ana Mighty Le Phono phono stage ? I am considering it as an upgrade from the Trilogy 907.
@audiofun , I am going to have a chat with Francois today. If all goes well I will get the Le Phono. The other phonostage I am considering is the FM Acoustics 122 mk2. I can get it for about 60% more than the Le Phono but it is one of those phonostages which has a solid reputation for being in a top-tier system. I have heard the FM and I love it.
@rauliruegas just curious where did you find the information on the RIAA deviation of 1db on the Le Phono ?
Francois is ready to send me a unit with 15 days return policy so that should settle the matter of how good it it. I will report here on the performance when I get it. 
I had a discussion with Anamighty guys on this and they clarified that they measure their RIAA from 1hz to 400khz. The deviation for that range is +-0.5db. But from 20hz to 20khz it is only 0.1db.
