FWIW with 50+ year old musician's ears I tested the Enigma PSU1 with a variety of GSP phono stages and didn't hear a clear difference on the MM stages. But I did on the EXP and on the AccMC. In all cases I was only running that piece of equipment off its own PSU1/Enigma. I couldn't do a blind ABX test on my own but did play several tracks or a whole side to get an overall feel for the music with each setup. I also did some needledrops which I still have and think the MM ones are similar with either PSU1 whereas the MC is clearer, better guitars, percussion, strings and more dynamic IMO with the Enigma. With respect to others' opinions and Graham's expertise I think the big step forward in the AccMC is the MC to MM boost stage which Graham has written about and the Enigma PSU1 is a step up from that. Put together they have the real sound of the EXP/AccMM I also own and overcome the technical issues (interference) of a small moving coil signal boosted up by over1000x. Technical stuff aside I have more fun listening to records on MC now. Edited by Fatmangolf - 14 Aug 2018 at 11:14pm |

I’ve never gone MC.
Mainly cos I can’t afford a good one & also because I’d have to by another phono stage. I’ve lost count of the comments I’ve had on the LP12 forum along the lines of: it’s just begging for a MC cart. Why would you put a MM (spit) cart on a highly modded LP12??!!
Has to be a L*nn MC cart or Denon Dl103. Thin I’m seen as a philistine/heretic for using a 2M Black.

Is the pursuit High Fidelity a sign of mental illness??
I think so.... |

When in Rome...  I am most sure that few if any turntable user realises the compromises involved in MC preamplification, and I wonder if they actually listen with their ears, or through their bias? Don't get me wrong: mechanically the MC is spot-on! It's just that the electronics required to match the darned things doesn't exist, never did, and never will! But to understand that requires an in-depth understanding of audio amplification, which the vast majority of them don't have. C******e Audio designer Doug Self, who I may disagree with on some issues (we've never met), but has to be accepted as one of the "greats", could only muster a head amp based around a NE5534 and 3 compounded transistors. A number of MC fanatics will be using that device built into the said companies phono stage (and many swear blind that they're the best). Unfortunately all feed-forward op-amps exhibit a false sound signature (OK, this is my opinion only) and the NE5534 is feed-forward. But all designers seem to forget, or didn't know, that what they're trying to amplify is a device (MM, MC or MI) which has a +6dB per octave rising response so as frequency increases signal voltage increases, and so bass to treble has signals differing by 60dB (corrected to 40dB by record EQ). You have groove noise of all kinds which isn't corrected by record EQ and goes beyond audio limits and so is more than a thousand to one in ratio, and an op-amp which changes its behaviour (due to feed-forward) between 200Hz and 10MHz. I wouldn't swear by it, I swear at it! But they all know best. They all know better than me. Even when my patent is granted hopefully within the coming weeks, they'll still all know better. Magnetic cartridge preamplification is a pain at the best of times. By making it 10 times more difficult (the MC outputs 1/10th on average less than MM) it becomes superior??? Yeah, it's crying out for it (indeed?)  |

Well they both work and I admire the technical skill necessary from experts like Graham to make this so. I am enjoying my Golding 1042 at the moment, admittedly through a very fine Accession M preamp. It is different to the Hana SL low output moving coil which the Accession MC gets the best out of in my opinion. Someone asked me recently about going to MC and I did share my view which is you'll spend a lot of effort and money to get the benefit. |

By the way I have been informed that my US patent grants on November 6th.

That's great news Graham. Is it for the Accession M? |

It covers the technology in the M and MC, and anything else which does similarly.
