SUT experience

"There is a principle which is a bar against all information, which is proof against all arguments and which can not fail to keep a man in everlasting ignorance-that principle is contempt prior to investigation."

If one thinks the 'Math' alone is the means to discover a device that is able to assist with producing a form of 'entertainment'. The likelihood is, the use of the Math only is dictating there is a lot of entertainment going to be overlooked, off which some discoveries not had, may be the ones that prove to excel over all others had.

Dear @billstevenson : I’m not afraid, things are that almost all what yu re-marks I already do it in the last 30+ years and I learned. Even I try sevral unortodox alternatives that in theory goes against the audiophile " rules " if any.

Things over those30+ years improved in the audio world and today I know what to do and what not to do. My time ( very large times. ) of experiment or test " things " contrary to the overall believes already past. I’m calm enjoying what I learned through all those time and a lot of spended money.

From those learning times 15 years ago came the Essential 3150 SS full phonolinepream that we designed and builded followed by the 3160 and today the Essential 3180, from those learning times came our own design and builded tonearm. Today I don't have to match any cartridge with any SUT or phono stage or tonearm, yes that good are what we builded. Today I don't buy any more any top LOMC cartridge but I already tested almost all in my system coming from my friends and about cartridges almost stay with no dramatic changes over the past but new refinements of wha we normally know. Gentlemans as mijostyn still are in that learning times on cartridges but cartridges have not the last word but the overall system chain.

Anyway thank’s for your observations.

@billstevenson  : Along all those I learned the critical importance of passive devices in the overall audio item designs, devices as  capacitors, resistors, fuses, power electrical connectors and the like. Examples are like these: all the power electrical system cables are hard wired directly to the boards/electrical path input and all those cables are made by silver material, my electronics has not any fuse at the lectrical power input ( yes, a little risky. ).

Certainly the best passive devices are not to use it but devices as capacitors or resistors almost always are need it. The speakers are directly tri-wired at the amplifiers outputs from each crossover filters. Yes all with silver wire including the ribbon silver inductors.

You can see in my Agon virtual system what I had in those learning times and in those pictures you can appreciate 3 TTs with 10 diferent tonearms ( I owned arond 20* ) and 10 diferent top cartridges ( I owned over 150. ).

Do you know how " discovery " the MM/MI cartridge quality levels? well that was in 2008 when I tested the first Essential 3150 with 4-5 MM/MI that I already owned but not used due that the corrupted AHEE teaches all of us that the name of the gaME IN CARTRIDGE WAS lomc ONES and that is totally false but to achieve the true MM/MI carrtridges quality real levels we need a very first rate MM phono stage and an excellent line stage that is what all Essential models have along a dedicated active higjh gain MC stage ( yes , the unit is SS . ). In all those and today days I never had/have to care about load cartridge impedance changes due that LOMC cartridge are not sensitive to that kind of load and in MM I work with 100koms instead 47kohms. Yes when I use the Denon 1000 SUT it looks 100kohms as load.

Nothing was or is at random and that's why I already understand your post: I lived the full experiences about. From there I learned about the experience to be seated at bnear field position in a live MUSIC events. First than aLL i'M A music LOVER and hardware is only a tool.

Btw, OMA does not have FR specs because almost no one " cares " about not only them that are sellers.
