MC transformers - what do they sound like?


Besides providing gain, are good quality MC transformers transparent to the signal they are providing the gain to. Or do they give added/reduced bass weight, more high end sparkle, added grain or what?.
This is obviously compared to active gain
It seems that audiophiles either luv or hate MC transformers?.

Raul- since you use a custom preamp I have no way to verify your results. How much gain does your preamp have? Have you plotted a distortion versus gain curve for your preamp? Have you plotted a noise versus gain curve? I would be interested in the results.
Sorry Raul I chekced your system description that gives 85db of gain and a signal to noise ratio of 82db. Is that across the bandwidth?
Raul My suggestion that you build a prototype of your preamp was somewhat "tongue in cheek"(I don't know if that expression translates into Spanish)given the spec's and the fact that it is a vendetta clone, it would be worht it.

Personally I wish someone could "soup up" My SP 14 with varialble load resistance and capacitance. Also with the latest elctronic components.

Mostly because I like its straight wire with gain approach and the controls on the front panel.

Sorry, Downunder I suggested, it so I'm first.
transformers were chosen because they are inherently quieter not because the designers were lazy. they were some aggresive pps' like the marcof.
Downunder-you certainly have thrown down the gauntlet!

Raul-Never enter into a conditional contract based on the customers satisfaction!:-)!
Raul what I learned ealry is this -insufficicient gain in the phono stage can make a great system sound meidocre. Agree? Y/N?
What we need is a preamp that has sufficient gain to drive the cornucopia of excellent low output mc cartridges? Agree y/n?
This means that we need a preamp with about 60-80db gain in the phono stage.Agree Y/N?
Optimally we also need about 80-100db S/N ratio(unweighted). AgreeY/N?
Luckily there exist a number of of preamps capable of this with no problem. They do tend to be expensive. Agree Y/N?
What does the audiophile do who is either unable to or uwilling to trash his current preamp in favor of one that can drive a low output preamp?
He can avail himself of an outboard pre-pre amp. Or he can avail himself of an outboard transformer. I took into consideration one parameter-noise.
The more you magnify the signal the more you magnify the noise (Ask DR. Dolby). Transformers make it easier to magnify the signal with less amplification of the noise. IME. Of course noise and gain have always been a bigger problem in tubes than solid state. Agree Y/N?
BTW you list a very impressive group of manufacturers who used SUT. you don't really mean to suggest they don't care about music?
Well in Luke Manleys' defense he clearly is using the transformer to lower the noise floor. Go to his website and check for yourself. I have stated before that frequency response especially in electronics remains the most overated spec ever. He does claim s/n of 100db.
I was referring to the father (David?). He designs the pruducts while the kids run the company.
My point is that a transformer can yield a lower noise floor than a comparable high gain preamp.
It osunds hofi? that same criticism was made of rhe vendetta.
