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.

Obviously YMMV, but I auditioned (all at the same time) the ARC Ref 3, Sim Audio 610P or 810P (don’t recall exactly which Sim unit it was, I know it costs about $8K), the Pass Labs XP25. There were a few other lesser priced units I also auditioned.

I probably liked the Pass the least as I found it thin sounding but airy and ethereal. It just had no substantative presence with the music. I also noted that it seemed to pick up more ticks and pops than the others. I think this can be a sign of high negative feedback BUT not necessarily. Nothing wrong with feedback, I am just saying I heard more ticks and pops on the same vinyl with the Pass.

I did not care for the ARC, I found it overly (artificially) warm and soft sounding. The music also had a quality of sounding like it was not riding on a firm foundation. I also found the prat to be wanting to my ears. I could not get an identifiable rhythmic flow out of the phonostage.

I did like some of the things the Sim Audio did, specifically it’s resolution, quietness and relative dynamism. I thought the prat again, was not quite where I would want it be, my foot just did not tap.

The SPL Phonos took the best of all of the above and took it to another level. The prat was awesome as well the dynamics. With my London it is nearly unbelievable. I would not use it with a super low gain cartridge unless you had a step-up as it can present some noise if you really have to turn the volume up super loud (it is not a problem with my 103r/103.3 and even played very very well with my MC Anna which has an output of only .2mv). Not sure if some of the noise I hear when the volume is high (read too high for comfort) is due to my area in the city. The iPhono 2 is quiet like a tomb as is the PH77. This unit runs a proprietary 120v rail system and it sounds very alive. This is studio gear so the designer frills aren’t there like a good deal of the audiophile stuff, just outstanding perfomance. It really is exceptional. Actually shocked me as I had never heard of it before I went into my buddies audio shop, but I found that I kept going back to the unit.

The PH77 is simply better but the Phonos at this point is the second best phono stage I have spent an appreciable amount of time enjoying. It is certainly not embarrassed by the PH77. I could easily imagine that on some types of music I may prefer the Phonos to the PH77 much as I prefer my London on jazz over my other cartridges.

These are just my ears opinions, as I stated, YMMV.

Thinking of trying a Tsar DST to compare to the London :)

Hope this helps.
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 ?
Pani: 

Not a problem. I play my .25mv rated 103's and they sound absolutely wonderful with black backgrounds at a very nice volume level, so a .5mv cart will be super quiet and smooth sailing. At 57dB of gain you are outputting .354 volts which is plenty. You can run it at 67 dB but I would suggest that is much more gain than you need. More than a few people, for whatever reason, use excessive gain on their phono stages and it always sounds bad to my ears. Sometimes less really is more. It probably has to do with how these items are marketed to people.
