When is it time to consider adding a SUT?

Dear @billstevenson : Parry? to you?. Why should I?

My point is easy: to have a dialogue where you and me speak about " oranges " and only want to be sure about.

All of us have some misunderstood audio subjects because audio is so wider whole subject. Here we are talking of phono stage and I need to know the main targets in a phono stage from you and that's all.

If you refuse to do it could be because: you really don't want my answers on your questions or you are not to sure on my specific question or just you don't want to do it.

The " ball " is in your " field ". Shall we play?

I passed the ball to you with my very open ended and reasonable questions.   There are no trick questions or traps in them.  You are free to answer them or not, and you are free to state any assumptions you wish in your reply.  I do not intend to engage further without the courtesy of your open answers. 

Two words come to mind: distance and irritation

Dear @billstevenson : I never leave a question with out give an answer.

You said: "  your open answers. "

For me, in audio, exist no open answers but many times are very elaborated answers because in audio each link depends of all and each other links in the audio chain.

An open answer as : yes or not or an  item model means nothing with out an explanation of the " open " answer.

The other side is that all audio human beens  understand audio subjects in different way and that's why dialogue/discussion sometimes is useless for every one.

You posted:

 """    My solid state reference has been a Lehmann Silver Cube  """

in the same post with your " open questions " and that tell me that is probable that you and me can talk on different audio subjects.

With all respect to Lehmann and its owners and to you I think you have a very low reference line. I'm not saying is a bad reference only that could be not a real reference to discuss your questions. It's curious that been a phono stage the manufacturer specs did not shows the RIAA deviation level. Why ? could be an interesting question for you and its owners.

SC is a SS design that use in its first gain stage a microphone amp chip and in the second gain stage another chip by BB and and an output buffer with FETs. Lehmann had its own way of thinking about. I never heard it in my system but through different system.

When I talk about SS phonolinepreamp SS designs certainly I'm refereing to a different kind of designs/performance where my only reference is live music.


Regards and enjoy the MUSIC not DISTORTIONS,
